Quenching induced hierarchical 3D porous g-C3N4 with enhanced photocatalytic CO2 reduction activity

Abstract

A novel tactic, cold quenching, was adopted to prepare hierarchical 3D porous g-C₃N₄ without using any additive agents or templates. The combination of increased light absorption, improved electron–hole separation and enhanced adsorption of CO₂, endows this fine structure with excellent photocatalytic CO₂ reduction performance.
