Enriching CO2 Activation Sites on Graphitic Carbon Nitride with Simultaneous Introduction of Electron‐Transfer Promoters for Superior Photocatalytic CO2‐to‐Fuel Conversion
Source abstract
Abstract
Limited CO2 adsorption and inefficient charge transfer of graphitic carbon nitride (g‐C3N4) have been the two major obstacles for its application in photocatalytic CO2 reduction. In this work, a new type of carbon nitride photocatalyst (K‐incorporated amino‐rich carbon nitride, K‐AUCN) is designed and prepared by a facile posttreatment of urea‐polymerized g‐C3N4 (UCN) using KOH as a chemical activation agent. The resultant K‐AUCN has not only enriched intrinsic amino groups for superior CO2 adsorption, but also incorporated potassium and carbon defects as electron promoters for efficient photocatalytic reduction of CO2 in the presence of water vapor. Compared to UCN, the photocatalytic CO2 conversion performance on K‐AUCN is drastically promoted by five folds with 7.7‐time increase in CO2 adsorption. This work not only presents a simple design of low‐cost photocatalyst for CO2 reduction with enhanced performance, but shall also inspire more rational design of efficient catalysts for photocatalytic reduction of CO2 and other specific photocatalytic reactions.
