Self-assembly construction of NiCo LDH/ultrathin g-C3N4 nanosheets photocatalyst for enhanced CO2 reduction and charge separation mechanism study
文献摘要：
Graphite phase carbon nitride(g-C3N4)is a promising catalyst for artificial photocatalytic carbon dioxide(CO2)reduction.However,the fast carrier recombination and the inadequacy of the CO2 reduction active site in g-C3N4 block the escalation of the perfor-mance.In this work,NiCo layered double hydroxide(NiCo LDH)nanoflowers were self-assembled with ultrathin graphite phase carbon nitride(g-C3N4)by an ultrasonic stirring strategy utilizing the Zeta potential difference.The formed NiCo LDH/ultrathin g-C3N4 nanosheets(LDH-CN)photocatalysts own the merits of rich active sites and Z-scheme heterojunction,which lead to the enhanced CO2 reduction activity and selectivity.The highest yields of CO and CH4 were 114.24 and 26.48 μmol·h-1·g-1,which were much greater than those of g-C3N4 and LDH.Meanwhile,the enhanced selectivity for CO confirmed the strong redox ability in the LDH-CN caused by the Z-scheme.The heterojunction-induced built-in electrical field can promote the separation and migration of photoinduced electrons and holes.This study provides a theoretical basis for designing high-performance photocatalysts.
