Abstract MoS2/S-doped porous g-C3N4 (MoS2/SPGCN) hybrids were fabricated via a facile calcination and ultrasound assembly method. Structural characterization indicated MoS2 nanosheets were successfully loaded on SPGCN isotype heterojunction hybrids. The MoS2/SPGCN photocatalysts showed more visible light absorption, larger specific surface area, and faster electron-hole separation. MoS2/SPGCN significantly accelerated Rhodamine B photodegradation under visible light irradiation, which was mainly because the enriched active sites, broadened visible light absorption, and newly-formed heterojunction between MoS2 nanosheets and SPGCN together suppressed the recombination of photoinduced electron-hole pairs. MoS2/SPGCN also showed excellent recyclability and chemical stability. Thus, this work presents a good strategy of designing efficient photocatalysts by substituting the single catalyst base with metal-free isotype heterojunction hybrids.
