Capturing full-spectrum of solar energy using TiO2 ordered suprastructures. The project aims to develop a titanium dioxide (TiO2) semiconductor that can use full-spectrum solar energy. Solar-driven photocatalytic processes have important applications in water decontamination and energy production. Their effectiveness is dictated by the semiconductor’s absorbance and conversion of photoenergy to chemical energy. Being inexpensive, chemically and mechanically robust, TiO2 is the most promising mat ....Capturing full-spectrum of solar energy using TiO2 ordered suprastructures. The project aims to develop a titanium dioxide (TiO2) semiconductor that can use full-spectrum solar energy. Solar-driven photocatalytic processes have important applications in water decontamination and energy production. Their effectiveness is dictated by the semiconductor’s absorbance and conversion of photoenergy to chemical energy. Being inexpensive, chemically and mechanically robust, TiO2 is the most promising material for the semiconductor. However, unmodified TiO2 only absorbs ultraviolet light (5 per cent of solar energy). With current progress made in visible absorbance, this project aims to significantly improve TiO2’s absorbance in near infrared by doping with upconversion lanthanides and rendering colloidal crystal suprastructures that can trap light.Read moreRead less
Medium temperature electrolysis for low-cost carbon dioxide utilization. Carbon dioxide is a notorious greenhouse gas. Its capture, and subsequent storage or utilization, is a major focus not only for researchers, but also for governments trying to meet their obligations of the Paris Agreement on climate change and for industries managing their legal and social responsibilities. This project aims to develop commercially viable medium temperature electrolysers to convert carbon dioxide into value ....Medium temperature electrolysis for low-cost carbon dioxide utilization. Carbon dioxide is a notorious greenhouse gas. Its capture, and subsequent storage or utilization, is a major focus not only for researchers, but also for governments trying to meet their obligations of the Paris Agreement on climate change and for industries managing their legal and social responsibilities. This project aims to develop commercially viable medium temperature electrolysers to convert carbon dioxide into value added chemicals using electricity from renewable sources. New design principles will be developed to generate highly active and selective catalysts with long-term stability. These electrolyzers will be integrated with carbon capture technologies to directly utilize captured carbon dioxide with high energy efficiency.Read moreRead less
