Oloye’s academic foundation was laid at the Federal Polytechnic, Ado Ekiti, where he obtained a National Diploma in Mechanical Engineering. Even at this early stage, his leadership qualities shone as he actively engaged in student governance. Driven by an insatiable thirst for knowledge, he transitioned to Adekunle Ajasin University (formerly Ondo State University), where he achieved a first-class honors degree in Chemistry. His tenure at the university was marked not only by academic brilliance but also by active participation in student affairs, serving as the Chairman of the Sports Committee for the Student Representative Council.

Recognising his outstanding academic prowess, Oloye was awarded a prestigious federal government scholarship to further his studies at the University of Aberdeen, Scotland. There, he delved into groundbreaking research focused on developing catalysts to enhance fuel efficiency—an area of immense significance to the global energy industry. His remarkable contributions found their way into leading scientific journals such as Fuel, Catalysis Today, and Journal of Applied Petrochemical Research, garnering him international acclaim and citations from distinguished researchers worldwide.

Oloye has made significant contributions to the field of petrochemical engineering with his recent work on molybdenum carbide catalysts, which are poised to revolutionise fuel conversion processes. By creating a highly efficient catalyst made from molybdenum carbide supported on sulfated zirconia, Oloye’s team has discovered a way to enhance the transformation of hydrocarbons, such as n-heptane, into more valuable fuel products.

The team’s catalyst is prepared by impregnating molybdenum trioxide (MoO₃) on sulfated zirconia, followed by a carburisation process in a methane/hydrogen mixture at a high temperature of 923 K. This unique method results in the formation of a well-dispersed Mo₂C phase, which plays a crucial role in hydroconversion reactions. In simple terms, this catalyst helps break down complex hydrocarbons into smaller, more useful molecules, such as iso-pentane and iso-hexane, under various temperature and pressure conditions.

One of the key findings of Oloye’s research is the impressive increase in the Research Octane Number (RON) of n-heptane, a key measure of fuel quality. Under certain conditions, the catalyst raised the RON of n-heptane from zero to around 50, which is a significant improvement. The research also showed that higher temperatures and low space velocities (the rate at which the reactants pass through the catalyst) can lead to substantial cracking, a process where large hydrocarbons are broken down into smaller ones. However, this also comes with a tradeoff, as excessive cracking can reduce the selectivity of desired products.

In addition, the team’s study of different catalysts, including platinum on sulfated zirconia, further explored the conversion of n-heptane into iso-heptane and other branched products, with selectivity towards iso-heptane at lower conversion levels. As the conversion increased, more cracked products were formed, with specific isomers like 3-methyl hexane dominating the results.

Oloye’s work also emphasises the importance of maintaining a balance between acidity and hydrogenation sites on catalysts. His studies on carbided molybdenum catalysts revealed that while Lewis acid sites remain stable during the transformation of the catalyst from oxide to carbide form, Brønsted acidity sites were reduced. This subtle adjustment helps fine-tune the catalyst’s performance, providing better control over the fuel conversion process and enhancing the overall efficiency.

This innovative research paves the way for more efficient, cleaner fuel production and highlights the importance of advanced catalysts in optimizing petrochemical processes. By improving the conversion of hydrocarbons and increasing the quality of fuels, Oloye’s discoveries offer promising solutions for industries looking to produce higher-performing, eco-friendly fuels.

His excellence in research did not go unnoticed, earning him the Principal Excellence Award and the coveted Royal Society of Chemistry Travel Awards. These accolades are a testament to his relentless pursuit of scientific advancement and his contributions to the global body of knowledge.
Beyond his research, he has carved a niche for himself as a transformative educator. His impact as a mentor and teacher is evident in the countless students he has trained, many of whom have gone on to excel in various scientific and industrial fields. His passion for education remains a driving force in shaping future generations of scientists.

The COVID-19 pandemic underscored Oloye’s expertise and the critical role he plays in public health. As part of the University of Saskatchewan team, he spearheaded efforts in monitoring SARS-CoV-2 RNA trends, providing invaluable data to health authorities. His findings influenced strategic decisions by key organisations, including the Public Health Agency of Canada and the Saskatchewan Health Authority. In the spirit of transparency and knowledge dissemination, his team made their research publicly accessible through the Global Institute for Water Security website.

While monitoring wastewater is not new, Oloye’s recent work has provided groundbreaking insights into the use of wastewater surveillance as a tool for monitoring the spread of COVID-19, offering a new way for governments and communities to stay ahead of viral outbreaks. By tracking SARS-CoV-2 RNA in raw influent wastewater from treatment plants across three Canadian Prairie cities, Dr. Oloye and his team have developed a more reliable method to monitor the virus that bypasses the biases of government regulations or individual behaviors that might influence traditional reporting.

One of the standout findings from Oloye’s research is the consistency of wastewater data across different population sizes, revealing trends in the emergence of variants of concern (VOCs) without being swayed by the direct actions of governments or individuals. For instance, the team observed the dominant VOCs in the three cities were the same but varied in the proportions of sub-lineages. During 2021, the Delta variant sub-lineages such as AY.12, AY.25, and AY.27 were prevalent, while in 2022, Omicron BA.1 emerged as the major strain before being overtaken by BA.2. The data also highlighted Saskatoon, the largest city in Saskatchewan, as the first to show new VOCs in Saskatchewan, suggesting that larger populations may act as early indicators of trends that smaller communities could experience later on.

What makes this research even more powerful is the development of a reliable pipeline for quantifying SARS-CoV-2 RNA in wastewater. This process incorporated normalization techniques that allowed for better comparisons with reported new cases, providing early warnings for surges in cases, with a lead time of approximately seven days. Notably, this method also identified key variants, such as Alpha and Delta, that were driving waves of infection. The inclusion of population normalization methods, such as using acesulfame K (a sweetener used in wastewater) as a reference, was particularly useful during dynamic periods like the holiday season when population movement was high, making it harder to estimate viral loads.

By using this wastewater surveillance method, Oloye’s team has addressed a critical gap in public health monitoring. Their work shows that wastewater can offer an accurate and consistent way to track virus spread, detect emerging variants, and prepare for potential surges, without being affected by biases or delays in individual case reporting. The introduction of population normalisation approaches also opens the door for more precise data, supporting informed decision-making at both local and national levels. This research highlights the growing role of environmental monitoring in the fight against pandemics and underscores Oloye’s dedication to improving public health systems through innovative science.

Currently serving as an Associate Clinical Scientist with the Saskatchewan Health Authority, Oloye leads the wastewater monitoring programme, pioneering initiatives to improve water quality across Saskatchewan. His expertise in developing and refining wastewater surveillance systems has positioned him as a thought leader in environmental health. Additionally, his dedication to training emerging scientists in this specialised field has further cemented his legacy as a trailblazer.

Oloye’s contributions extend far beyond the laboratory and classroom. A respected figure in the scientific community, he has been invited to speak at numerous international conferences, often serving as a session chair or guest editor for esteemed journals. His extensive peer-review work underscores his standing as an authority in his domain.

A beacon of excellence and a symbol of what relentless dedication can achieve, Dr. Femi Oloye’s journey is nothing short of inspiring.
