Photocatalysis on the nano scale and related photophysical and photochemical phenomena.

 

 

Research

The solar-driven photocatalytic splitting of water into hydrogen and oxygen is a potential source of clean and renewable fuels. However, four decades of global research have proven this multi-step reaction to be highly challenging. The design of effective artificial photo-catalytic systems will depend on our ability to correlate the photocatalyst structure, composition, and morphology with its activity.
The group’s research is concerned with unique design of innovative nano scale particles, which harness nano phenomena for improved activity, and methodologies for the construction of sophisticated heterostructures tailored for photocatalysis and energy conversion. The laboratory’s cutting-edge synthetic effort is combined with fundamental research focused on the dynamic and mechanism of photo-induced charge transfer processes, across the different components of 1the photocatalyst system and further into the solution.

Figure caption: Illustration of a nanoscale photocatalyst composed of a CdSe quantum dot (green) embedded in a CdS nano-rod (yellow) with a platinum particle on its opposite tip (purple). This system set a record for the photocatalytic water splitting reduction half reaction with a perfect, 100%, photon to hydrogen conversion efficiency.
