21 Dec 2021 - Together with Prof. Chak Chan, Dr. Theodorah Nah, Dr. Chunhua Liu and Dr. Jin Shang, Dr. Ng receives another HKSAR Green Tech Fund (GTF) of over HKD$5 million to develop a new sensors for ambient air monitoring of BTEX and volatile organic compound (VOC) pollutants. 

Welcome to Dr. Yun Hau Ng's research website. Dr. Ng is an associate professor in the School of Energy and Environment at the City University of Hong Kong. His research focuses in the area of alternative and renewable energy through the approach of catalysis - namely photo(electro) catalysis, electrocatalysis and carbon (thermal) catalysis. Hydrogen generation from water (or waste water), photo-induced charge storage (solar battery), electrocatalysed oxygen evolution, liquid junction photoactive semiconductor thin films are within my expertise. The research team uses a multidiciplinary approach, involving internal and external collaborations along with students from Chemical Engineering, Chemistry, Materials Science, Photovoltaic and Physics, to study nanostructured materials as active components in energy conversion and storage processes. 

His research aims at gaining fundamental understanding involved in these areas with the ultimate goal to achieve real life application in industry. We observe experimental phenomena, study the fundamental principles lie underneath that guide the overall reactions in light energy conversion-storage. Investigation into the basic science equips us the ability to engineer better and more efficient systems for practical uses.
