Revolutionising Sustainable Energy Through Catalytic Innovation

Catalysis can accelerate chemical reactions and plays a key role in producing cleaner and more economical fuels.  On 17 September 2025, Prof. WANG Yong from Washington State University, USA, delivered a PAIR Distinguished Lecture titled “Catalysis: Driving Affordable Clean Energy”.  He shared insights into the potential of advanced catalytic technologies in revolutionising fuel production and reducing emissions.  The lecture attracted over 120 in-person attendees, with more than 17,900 online viewers tuning in via various social media platforms. At the beginning of his talk, Prof. Wang explained the definition of catalysis: the use of catalysts to lower the activation energy required to initiate a chemical reaction, thereby enabling reactions to proceed more rapidly and efficiently with minimal energy input.  An excellent catalyst must possess high stability to effectively facilitate the interactions among reactants to form products. Prof. Wang then introduced his team’s research achievements in the field of the Fischer-Tropsch process.  They discovered that this process, developed in the last century, can convert coal, natural gas or biomass into liquid fuels, and that its reaction rate naturally fluctuates between high and low levels.  This intriguing phenomenon may pave the way for more efficient fuel production in the future. Prof. Wang also discussed how catalytic converters in vehicle exhaust systems use metals such as platinum, palladium, and rhodium to purify emissions and reduce pollutants.  He pointed out that hydrothermal ageing techniques can be used to stabilise single-atom catalysts and enhance their catalytic activity. In summary, these studies demonstrate the immense potential of advanced catalytic technologies in revolutionising fuel production and emissions control, laying the foundation for cleaner and more efficient energy systems. The subsequent question-and-answer session was chaired by Prof. WANG Lianzhou, Chair Professor of Energy Materials in the Department of Applied Biology and Chemical Technology.  Both in-person and online audiences engaged in fruitful exchanges and discussions with the two professors.

PolyU’s study reveals potential planetary health impacts of the airborne plastisphere

Prof. Nathanael JIN Ling, Member of the Research Institute for Future Food (RiFood), the Research Institute for Sustainable Urban Development (RISUD) and the Mental Health Research Centre (MHRC), and Assistant Professor in the Department of Civil and Environmental Engineering and the Department of Health Technology and Informatics, has recently published an invited review paper in One Earth by Cell Press, examining the planetary health impacts of the airborne plastisphere. Microplastics are a ubiquitous yet long-overlooked component of airborne particulate matter.  The surface of these plastic particles provides a unique niche for microorganisms, collectively referred to as the plastisphere.  In aquatic and terrestrial ecosystems, the plastisphere harbours microbial communities with distinct compositions, structures and functional profiles, posing potential risks to planetary health.  However, the characteristics, fate and impacts of the microbiome associated with airborne microplastics remain largely unknown. In this review, the team addressed these knowledge gaps by exploring how airborne microplastics serve as key habitats for microorganisms and the potential implications for planetary health.  They demonstrated that microplastics are likely to transport and sustain microorganisms over long distances and timescales in the atmosphere, potentially dispersing pathogens, antibiotic resistance genes and other bioactive agents across ecosystems.  Such interactions may disrupt ecological processes and biological health on a planetary scale.  Prof. JIN emphasised that interdisciplinary research and innovative methodologies are urgently required to better understand and mitigate the risks associated with the airborne plastisphere.
