Hybrid Materials: A Crucial Role of Rh Substituent Ion in Photoinduced Internal Electron Transfer and Enhanced Photocatalytic Activity of CdS–Ti_(5.2–x)/6Rh_x/2O₂ Nanohybrids (Small 43/2015)

An effective methodology to optimize the photorelated functionalities and photostability of semiconducting nanocrystals is developed by Y.-R. Kim, S.-J. Hwang, and co-workers. On page 5771, they adopt Rh-substituted titanate nanosheets as a hybridization matrix. The Rh ion plays a crucial role in the internal electron transfer of the nanohybrids. The CdS–Ti(5.2−x)/6Rhx/2O2 nanohybrids show high visible-light photocatalytic activity for H2 production, highlighting the usefulness of composition control in optimizing the photofunctions of nanosheet-based hybrid materials.
