Steering charge kinetics in metal-free g-C3N4/melem hybrid photocatalysts for highly efficient visible-light-driven hydrogen evolution
Source abstract
Abstract
Abstract The low efficiency of photogenerated charge separation is a critical factor to restrict the efficiency of photocatalytic reaction. Extensive research efforts have been devoted to charging kinetics to improve the efficiency of photogenerated charge separation and transfer to catalytic sites. In this research, the heterostructure and interfacial electron polarization are formed between melem and graphitic carbon nitride (g-C3N4) through first-principles calculation, which can greatly suppress the electron-hole recombination. The synergistic advantage of g-C3N4/melem hybrid reveals great enhancement in photocatalytic hydrogen activity. Subsequently, we prepared the composite material of g-C3N4/melem by molecular engineering strategy, and found that the photocatalytic efficiency of g-C3N4/melem was twice of pristine g-C3N4. This study provides an insightful idea to improve the efficiency of photogenerated charge separation.
