Symposium EN18—Multiscale Designing and Constructing Photocatalytic Materials for Solar Fuels
Photocatalysis that can convert abundant but intermittent solar energy into storable chemical energy represents an amazing technique route to produce energy for a sustainable modern society. Splitting water to release hydrogen and reducing carbon dioxide in the presence of water to produce hydrocarbons with solar-driven photocatalysts/photoelectrodes are two highly concerned yet very challenging reactions. Designing and constructing photocatalytic materials at multi-scales will play a pivotal role in fully steering three basic processes (light absorption, separation of photogenerated charge carriers in bulk, and their transfer on surface) of photocatalysis facing these two reactions. No doubt, numerous experimental and theoretical progresses in understanding and modulating photocatalytic materials achieved at different scales from atomic to nanometer levels has greatly promoted solar-driven photocatalysis. More importantly, these progresses have established a strong basis for making the new breakthroughs that will require researchers investigating photocatalytic materials at different scales to put their ideas and understandings together. This symposium will encourage an integration toward the construction of highly efficient photocatalytic materials at multi-scales and will provide a medium for both experimentally and theoretically based discussions of photocatalytic materials.
