Photocatalysis, as an inexpensive and safe technology to convert solar energy, is essential for the efficient utilization of sustainable renewable energy sources. Earth-abundant cobalt sulfide-based composites have generated great interest in the field of solar fuel conversion because of their cheap, diverse structures and facile preparation. Over the past 10 years, the number of reports on cobalt sulfide-based photocatalysts has increased year by year, and more than 500 publications on the application of cobalt sulfide groups in photocatalysis can be found in the last three years. In this review, we initially summarize the four common strategies for preparing cobalt sulfide-based composite materials. Then, the multiple roles of cobalt sulfide-based cocatalysts in photocatalysis have been discussed. After that, we present the latest progress of cobalt sulfide in four fields of photocatalysis application, including photocatalytic hydrogen production, carbon dioxide reduction, nitrogen fixation, and photocatalytic degradation of pollutants. Finally, the development prospects and challenges of cobalt sulfide-based photocatalysts are discussed. This review is expected to provide useful reference for the construction of high-performance cobalt sulfide-based composite photocatalytic materials for sustainable solar-chemical energy conversion.

“…However, these transition metal oxides and hydroxides usually have poor conductivity, limiting the migration efficiency of photogenerated charge carriers . Incorporating electrically conductive graphene with transition metal hydroxides could tackle this dilemma. − For example, Xu et al recently developed graphene-modified alkaline transition metal hydroxides as cocatalysts for the photoreduction of CO 2 , and they demonstrated that the different transition metal-based hydroxides could selectively produce CO or H 2 gas in diluted CO 2 . However, the detailed reaction mechanism for selectively forming CO or H 2 was unclear and the ratios of CO/H 2 syngas were fixed.…”

The conversion of diluted CO 2 into tunable syngas via photocatalysis is critical for implementing CO 2 reduction practically, although the efficiency remains low. Herein, we report the use of graphene-modified transition metal hydroxides, namely, Ni X Co 1−X -GR, for the conversion of diluted CO 2 into syngas with adjustable CO/H 2 ratios, utilizing Ru dyes as photosensitizers. The Ni(OH) 2 -GR cocatalyst can generate 12526 μmol g −1 h −1 of CO and 844 μmol g −1 h −1 of H 2 , while the Co(OH) 2 -GR sample presents a generation rate of 2953 μmol g −1 h −1 for CO and 10027 μmol g −1 h −1 for H 2 . Notably, by simply altering the addition amounts of nickel and cobalt in the transition metal composite, the CO/H 2 ratios in syngas can be easily regulated from 18:1 to 1:4. Experimental characterization of composites and DFT calculations suggest that the differing adsorption affinities of CO 2 and H 2 O over Ni(OH) 2 -GR and Co(OH) 2 -GR play a significant role in determining the selectivity of CO and H 2 products, ultimately affecting the CO/H 2 ratios in syngas. Overall, these findings demonstrate the potential of graphene-modified transition metal hydroxides as efficient photocatalysts for CO 2 reduction and syngas production.
