Personal profile


Dr. Ng Boon Junn obtained his BEng and Ph.D. degrees in Chemical Engineering from Monash University Malaysia in 2015 and 2019, respectively. Currently, he is a Research Fellow in the School of Engineering, Monash University Malaysia. He is an early career researcher who is active in the field of functional materials, photocatalysis and nanotechnology. His research primarily focuses on the rational design and development of highly efficient Z-scheme photocatalytic system for solar energy conversion. In 2020, he was awarded the Highly Commended Award for IChemE Malaysia Young Researcher Category. He has attended several key conferences related to photocatalysis, and obtained the Best Research Award for the 1st International Conference (Virtual) on Sustainable Energy and Catalysis (ICSEC 2021, Malaysia) and the Best Poster Award for the 2nd International Workshop on Graphene and C3N4-based Photocatalyst (IWGCP2, Wuhan, China). His work on the development of Z-scheme photocatalytic systems has evoked new breakthrough findings in solar-to-chemical conversion applications and emanated in rich knowledge for clean energy alternatives.

Research interests

As the world decides on the next giant step for the renewable energy revolution, numerous attempts have been made to mimic the natural photosynthesis system of green plants by converting solar energy into chemical fuels. A recreation of this system can be witnessed in the photoconversion process which presents an intriguing avenue to mitigate the onslaught of energy crisis and to realize a long-term clean energy driven society. The forefront of solar energy conversion research focuses on the photocatalytic hydrogen production from overall water splitting. However, overall water splitting from pure water without any sacrificial reagent under ambient condition is a daunting challenge due to the stringent requirements of photocatalyst. Besides, particulate photocatalysis is often conducted in powder suspension form which hinder the potential for large-scale application. With the ultimate ambition of realizing large-scale and industrialized photocatalytic technology, my research interests include the rational design and development of photocatalytic Z-scheme water splitting systems in both particulate form and miniature device for solar energy conversion. In this regard, the unique Z-schematic arrangement of two photocatalysts connected by an electron mediator can realize efficient overall water splitting via two-step photoexcitation process. Furthermore, the fabrication of novel advanced materials with ingenious arrangement of photocatalytic configuration provides in-depth understanding of the fundamental mechanisms associated to the high solar efficiency. Other than the fabrication of photocatalysts in nanoscale, another highlight of my research focuses on the potential up-scaling of this technology. The fabrication of Z-scheme system in dual-layer configuration of wireless particulate photocatalyst sheets offer a potential upscaling approach for overall water splitting. In the hopeful future, highly efficient water splitting device can be methodically realized in driving large-scale solar hydrogen production.
