Research Abstract

Layered transition metal nanosheets, which possess ~1 nm thickness and lateral dimensions of several hundreds of nanometer to a few micrometer, are promising materials as photocatalysts that are capable of producing H_2 and O_2 from water. This research highlighted that photocatalytic activity of nanosheets is strongly dependent on the thickness and distortion of the sheet layer. It was also found that doping with foreign metal cations into nanosheets function as potential photocatalysts for visible-light-driven water splitting.
