Abstract

The charge kinetics of semiconductors determines the efficiency of photocatalysis reactions. Herein, the adjusting charge kinetics was investigated based on the integration of LSPR effect with homojunction. To this end, a novelty phosphorus (P)-doped fiber tubular graphitic carbon nitride (g-C3N4)/g-C3N4/titanium nitride (TiN) composite (FCN/CN/TiN) was designed for this work. The features of adjusting charge kinetics were reflected in optical and photo-electrochemical measurements. The availability of the adjusting charge kinetics was evaluated by the photocatalytic degradation of the typical recalcitrant fungicide carbendazim. The mechanism of integrating LSPR effect with homojunction for adjusting charge kinetics of g-C3N4 was systematically investigated and deepened the understanding of the thermodynamic reaction through DFT calculations. Especially, the specific roles of LSPR effect in adjusting charge generation kinetics, i.e. charge transfer, or energy transfer or both they was elaborated. The integration of LSPR effect with homojunction would provide a new strategy for adjusting charge kinetics of semiconductors in photocatalysis.
