Global warming caused by greenhouse gases, predominantly carbon dioxide, will be the most threatening issue facing us in this century. Dr Wey Yang Teoh, Associate Professor in the School of Energy and Environment at CityU in partnership with Dr Alex Chi Kin Yip, Senior Lecturer in the Department of Chemical and Process Engineering at the University of Canterbury, New Zealand led the project by replicating the structure of natural leaves, produced the titanium dioxide (TiO2) artificial leaves, which can be used as a platform to convert carbon dioxide into precious chemicals using sunlight and water.
"We believe that sustainable carbon dioxide capturing and conversion into valuable products such as formic acid, methanol and methane are viable pathways in dealing with carbon dioxide emission," said Dr Teoh. "The project holds great promise because it was driven mainly by sunlight and water, both are sustainable and renewable resources" he added.
Dr Teoh and Dr Yip are key members of the Joint Laboratory for Energy and Environment Catalysis at CityU with other team members from Australia, Spain, the United States and Germany. The lab is dedicated to advancing globally important reactions such as the production of clean hydrogen, biomass conversion, the destruction of carcinogenic compounds in drinking water and tackling air pollution.(Adapted from CityU NewsCentre) Back
