A Novel Dual Z-Scheme Visible Light Catalyst PCN/BiOCl/CdS with Oxygen Vacancies for Benzylamine Oxidative Coupling Reaction
Here we report a strategy to prepare a novel ternary dual Z-scheme PCN/BiOCl/CdS photocatalyst by in-situ introducing bismuth oxychloride (BiOCl) on porous carbon nitride (PCN) and then depositing cadmium sulfide (CdS). The synthesized PCN/BiOCl/CdS not only has the porous structure of PCN and the wide visible-light absorption range of CdS, but a special morphology and abundant oxygen vacancies of BiOCl under the action of the structure-directing agent ethylene glycol. Through the modulation of oxygen vacancies, the BiOCl in the PCN/BiOCl/CdS can be excited under visible light, thereby further improving its optical properties. The PCN/BiOCl/CdS exhibited excellent photocatalytic activity in oxidative coupling reaction of benzylamine under visible light. The excellent catalytic performance of PCN/BiOCl/CdS photocatalyst was due to high charge separation efficiency, oxygen vacancies and visible light absorption. Finally, we proposed a feasible photocatalytic mechanism for the PCN/BiOCl/CdS in oxidative coupling reaction of benzylamine.
期刊介绍：
Early dissemination of important findings from Asia which may lead to new concepts in catalyst design is the main aim of this journal. Rapid, invited, short reviews and perspectives from academia and industry will constitute the major part of Catalysis Surveys from Asia . Surveys of recent progress and activities in catalytic science and technology and related areas in Asia will be covered regularly as well. We would appreciate critical comments from colleagues throughout the world about articles in Catalysis Surveys from Asia . If requested and thought appropriate, the comments will be included in the journal. We will be very happy if this journal stimulates global communication between scientists and engineers in the world of catalysis.
