Co_0.9Co_0.1S Nanorods with an Internal Electric Field and Photothermal Effect Synergistically for Boosting Photocatalytic H₂ Evolution.

ABSTRACT: The paper reports a strategy to synthesize Cd_0.9Co_0.1S nanorods (NRs) via a one-pot solvothermal method. Remarkably, the pencil-shaped Cd_0.9Co_0.1S NRs with a large aspect ratio and good polycrystalline plane structure significantly shorten the photogenerated carrier transfer path and achieve fast separation. An appropriate amount of Co addition enhances visible light-harvesting and generates a photothermal effect to improve the surface reaction kinetics and increases the charge transfer rate. Moreover, the internal electric field facilitates the separation and transfer of carriers and effectively impedes their recombination. As a result, the optimized Cd_0.9Co_0.1S NRs yield a remarkable H₂ evolution rate of 8.009 m
