Photocatalytic hydrogen evolution (PHE) via water splitting using semiconductor photocatalysts is an effective path to solve the current energy crisis and environmental pollution. Heterojunction photocatalysts, containing two or more semiconductors, exhibit better PHE rates than those with only one semiconductor owing to the altered band alignment at the interface and stronger driving force for charge separation. Traditional binary metal sulfide (BMS)‐based heterojunction photocatalysts, such as CdS, MoS2, and PbS, demonstrate excellent PHE performance. However, the recently developed multinary metal sulfide (MMS)‐based photocatalysts possess favorable chemical stability, tunable band structure, and flexible element compositions, and have considerable potential to realize higher PHE rates than those of BMSs. In this review article, the mechanism of PHE is first elucidated and then various single and heterojunction MMS‐based photocatalysts and their charge transfer behaviors and PHE performances are systematically summarized. A perspective on potential future research directions in this field is concluded.

“…Recently, a low-cost TMS CuSbS 2 photocatalyst has been developed and applied for hydrogen evolution, achieving the highest hydrogen production rate to date of 2140 μmol g À 1 h À 1 . [91] The type II CuSbS 2 /TiO 2 heterojunction has also been used for the photodegradation of rhodamine B. [92] Therefore, the development of CuSbS 2 /TiO 2 heterojunction photocatalysts can guide the selection of low-cost elements to fabricate TMS/TiO 2 photocatalysts with potentially very high photoactivity and enable large-scale applications.…”

The development of efficient and stable photocatalysts is key to achieving highly efficient photocatalytic hydrogen evolution. Compared with photocatalysts containing only one type of semiconductor, heterojunction structure photocatalyst combining two or more semiconductors show altered band alignment at the interface, which promotes the separation of photogenerated carriers and inhibits carrier recombination. Thus, this kind of photocatalysts usually exhibit higher hydrogen evolution rates. To date, binary‐metal‐sulfide/titanium oxide (BMS/TiO2) heterojunction photocatalysts, such as CdS/TiO2, MoS2/TiO2, and ZnS/TiO2, have shown great promise for photocatalytic hydrogen evolution. Compared with BMS/TiO2, recently developed ternary‐metal‐sulfide/TiO2 (TMS/TiO2) photocatalysts have the advantages of low toxicity, a tunable band structure, and favorable chemical stability, enabling a higher photocatalytic hydrogen evolution rate. In this review, TMS/TiO2 heterojunction photocatalysts are thoroughly summarized and the semiconductor properties of TMSs are firstly introduced. Afterwards, photocatalytic hydrogen evolution applications based on TMS/TiO2 heterojunction photocatalysts are reviewed and discussed in detail, mainly focusing on the heterojunction type, band structure, and photogenerated carrier separation and transport. Finally, our conclusions and the perspective based on the potential for the further improvement of TMS/TiO2 based photocatalysts are presented.

“…Furthermore, the morphology and phase composition of nanoparticles have a great influence on their photocatalytic performance. There are some reports on the controllable morphology and phase structure of CuSbS 2 nanoparticles by adjusting reaction temperature, reaction time and the ratio of metal to sulfur in the precursor solution [6][7][8]. John B et al [9] prepared CuSbS 2 nanoparticles by solvothermal method, and explored the effect of reaction temperature on the phase structure of CuSbS 2 nanoparticles.…”

CuSbS2 is a direct p-type semiconductor with a two-dimensional layered structure of orthorhombic system, excellent electrical performance, and a band gap of 1.1-1.5 eV, which has a light absorption coefficient of more than 104 cm-1 in the visible light range. CuSbS2 particles were synthesized by microwave irradiation method, and the effects of different sulfur sources on the phase structure, morphology and electrochemical performance of CuSbS2 particles were studied. The results showed that the sample prepared by thiourea as sulfur source was CuSbS2 phase, and the morphology was composed of flower-like microspheres and rod-like particles. However, nanorod-like CuSbS2 particles were obtained using L-cysteine or 3-thiopropionic acid as sulfur sources, and the phase of samples contained CuSbS2 and Sb2S3 phase. Electrochemical tests showed that L-cysteine based CuSbS2 particles had the largest photocurrent response, a photocurrent density of 1.03 μA/cm2 and impedance of 14.66 Ω.
