摘要： Tetracycline (TC) is difficult to degrade and is widely used, seriously threatening the environment and human health. This paper employed the two-step hydrothermal synthesis process to combine the different loading of urchin-like In2O3 with laminar g-C3N4. After a series of experiments, it was proved that the 10.0wt.% In2O3/g-C3N4 is the optimal ratio. Its decompose efficiency of TC could reach 86.1%, and the apparent rate constant of degradation was 0.01655min-1-1 simultaneously. This result is attributed to the S-scheme heterojunction structure within the In2O3/g-C3N4 composite material. Through this mechanism, useless electrons and holes were eliminated via recombination, while the highly reactive photogenerated electrons in the g-C3N4's CB and the holes in the In2O3's VB were reserved for photocatalytic reactions and generated a substantial quantity of reactive species (RSs) that effectively degraded TC. This work provides several useful insights for removing TC or other organic pollutants from the water environment.
