Time-Resolved Electron Microscopy for In-Situ Study of Photocatalytic Water Splitting Reaction
DescriptionPhotocatalytic hydrogen production is believed to be one of the most promising method to generate hydrogen which has been recognized as a future energy carrier. Currently, liquid environmental TEM experiments for characterizing photocatalytic reaction evidences that an electron beam can dissociate water molecules and simultaneously modify surface of metal oxides which leads for simultaneous photocatalytic reaction and radiolysis. The radiation damage due to electron beam/ sample interaction can be controlled via lowering down accelerating voltage and the dose rate of the incident electrons. Here, we propose to investigate the dynamics of photocatalytic reaction and hydrogen storage in water using aTime-ResolvedAberrationCorrectedEnvironmental (TRACE) transmission electron microscope (TEM). This unique TEM has a special nano-second pulse electron gun and is equipped with double aberration corrector. The pulse electron source play two roles that are to control the radiolysis and also to record high space/ time resolved dynamics of the observing object.
