LIMITED LAYERED M0S2 NANOSHEETS AS NOVEL PHOTOCATALYST FOR SOLAR HYDROGEN PRODUCTION FROM THE SPLITTING OF WATER

摘要

Hydrogen, as an ultimately clean and completely carbon neutral energy carrier, has been considered as an ideal alternative for the conventional energy sources such as crude oil and natural gases. A revolutionary work was reported on 1972 showing that hydrogen can be generated from the photoelectrochemical splitting of water by using TiO2 and Pt electrodes. This groundbreaking work opened up a promising scenario of producing hydrogen by the reign of infinite solar energy. Since then, a tremendous research interests has been devoted into this field. During the past few decades, a myriad of semiconductors have been fabricated and/or examined for photocatalytic hydrogen evolution from the cleavage of water under various experimental conditions.
