Simultaneous Photocatalytic Oxygen Production and Hexavalent Chromium Reduction in Ag3PO4/C3N4 S-scheme Heterojunction
文献摘要：
The low separation/migration efficiency is a major obstacle that limits the practical application of semiconductor-photocatalysts. Con-structing S-scheme heterojunction is an ideal strategy for providing high photocatalytic activity via accelerating charge separation. Herein, an Ag3PO4/C3N4 composite was synthesized by coupling Ag3PO4 particle with C3N4 hollow spheres in-situ via a precipitation method. The S-scheme hete- rojunction between Ag3PO4 and C3N4 could accelerate the charge separation and retain high photoredox ability, which synchronously real-ized high photocatalytic oxygen production and hexavalent chromium re-duction. The optimized Ag3PO4/C3N4 composite shows a high oxygen pro-duction rate up to 803.31 μmol·g-1·h-1 and a high conversion (87.9％) of Cr(VI) to Cr(III). In addition, C3N4 hollow spheres affords higher reaction efficiency than that of C3N4 tube, C3N4 bulk and C3N4 sheet, which indicates that the hollow sphere structure can provide more active sites and adsorption sites in the photocatalytic process. This work offers an effective way in developing a dual-function S-scheme heterojunction for clean energy production and environmental protection.
