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.

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
Two-dimensional nanoporous structured high performance gas evolution electrocatalysts. This project aims to develop nano-catalysts with high catalytic activity and rapid gas detachment properties for efficient fuel gas production. Heterogeneous electrocatalytic gas evolution reactions are important for clean energy generation and storage technologies, but high overpotentials caused by slow gaseous products’ detachment from catalyst surface severely hinder their efficiencies. Expected outcomes in ....Two-dimensional nanoporous structured high performance gas evolution electrocatalysts. This project aims to develop nano-catalysts with high catalytic activity and rapid gas detachment properties for efficient fuel gas production. Heterogeneous electrocatalytic gas evolution reactions are important for clean energy generation and storage technologies, but high overpotentials caused by slow gaseous products’ detachment from catalyst surface severely hinder their efficiencies. Expected outcomes include insights into gas bubble formation and evolution during electrocatalysis, effective catalyst structures to mitigate negative effects of gas bubble formation, and improved catalytic efficiency of gas evolution reactions and develop high performance electrocatalysts for fuel gas production.Read moreRead less
Scale-up of catalytic furandicarboxylic acid production at room temperature. This project will use new knowledge acquired from our laboratory-scale discoveries to develop a new process feasible for industrial-scale production of 2,5-furandicarboxylic acid (FDCA). The method makes FDCA, a platform chemical for future chemical industry, from a completely renewable source derived from plant sugars, 5-hydroxymethyl-furfural. This is an essential process for production of biodegradable plastic from s ....Scale-up of catalytic furandicarboxylic acid production at room temperature. This project will use new knowledge acquired from our laboratory-scale discoveries to develop a new process feasible for industrial-scale production of 2,5-furandicarboxylic acid (FDCA). The method makes FDCA, a platform chemical for future chemical industry, from a completely renewable source derived from plant sugars, 5-hydroxymethyl-furfural. This is an essential process for production of biodegradable plastic from sugar that has not been commercialised. This technology will realise sizeable industrial-scale production of FDCA at low costs and without heating. The production development of this valuable commodity from renewable plant sugars will provide high-quality postgraduate training in future green chemical production methods.Read moreRead less
