AbstractHeterogeneous photocatalysis, as an energy-saving technology, is a fascinating strategy to tackle environmental issues and energy shortages. The efficacy of these processes severely relevant the suppression charges recombination, which hinders widespread utilization processes. segregation from fast recombination can be considerably improved by formation heterojunction among components photocatalysts. Nevertheless, formed between different semiconductors diminishes continuity carriers transfer amongst semiconductors. Moreover, construction heterojunctions significantly relies on matching band structures desired Hopefully, homojunction exposing facets, morphologies, crystal phases single semiconductor feasible for impressively recombination. In comparison with photocatalysts, almost identical in both sides junction area provide not only incredibly matched lattice, but also integrity bonding counterparts, facilitates charge migration within photocatalyst. Furthermore, established built-in electric field regions could enforce efficiently separation Herein, we reviewed latest researches about emerging photocatalysts their application degradation various wastewater pollutants. present review intends stimulate research communities focus this kind materials, impressive performances photocatalytic processes.Keywords: Energy conversionenvironmental crisishomojunction photocatalystseparation carrierswastewater treatmentHANDLING EDITORS: Jose-Julio Ortega-Calvo Lena Q.
