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. 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 systems in both particulate form and miniature device for solar energy conversion. 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.

Research Projects

Title: Development of photocatalytic water splitting system with Z-scheme configuration for highly efficient and scalable hydrogen evolution under ambient condition

From past to present, particulate photocatalysis is conducted in powder suspension form. With the progressive research efforts in developing efficient photocatalytic systems for durable solar water splitting, it is timely to deliberate on scaling up of this technology for practical application. 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. Therefore, the research primarily focuses on the rational design of photocatalytic water splitting system in Z-scheme configuration. The ingenious arrangement of two photocatalysts connected by an electron mediator can realize efficient overall water splitting via two-step photoexcitation process. One step further is to develop a wireless Z-schematic device to drive scalable overall water splitting. The fabrication of Z-scheme system in dual-layer configuration of 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.
