BiOBr/CuInS2/WO3 heterojunction is formed using a straightforward physical mixing method, whereas pure photocatalysts (CuInS2, WO3) were synthesized hydrothermally and BiOBr by a coprecipitation process. The Field Emission Scanning Electron Spectroscopy examination validated the nanorod and nanosheet shape of the fabricated BiOBr-CuInS2-WO3. The photodegradation capabilities of the BiOBr-CuInS2-WO3 heterojunction were superior to those of other pure photocatalysts, and it followed the S-scheme charge transfer route as indicated by the band alignments. After 120 min of light irradiation, the BiOBr/CuInS2/WO3 S-scheme ternary heterojunction obtained a photodegradation rate of 98.9 %, much greater than other pure photocatalysts. According to electron spin resonance investigations and scavenging experiments, the radicals hydroxyl radicals (•OH), hole (h+), superoxide (•O2−) play a significant role in the photodegradation of TC. The ternary heterojunction's improved light absorption, lower recombination rate, and higher photocarrier separation rate were due to the fabrication of S-scheme heterojunction. The ternary BiOBr/CuInS2/WO3 photocatalyst's photodegradation efficacy was consequently enhanced.
