“…MoS 2 has narrow energy band and could be excited by visible light. However, the energy band is unmatched, the valance band is positive enough, which makes the catalyst with good oxidative ability [15][16][17], while the conductive band is not negative enough, the reductive ability is very poor [18][19][20]. All these defects decrease catalytic activity seriously.…”

“…Among of all ternary combinations, the best stability in photodegradation was observed for the KTaO 3 + CdS + MoS 2 (10:5:1) sample (prepared via 2-step synthesis). Based on position of valence and conduction band [12,24,25], it could be proposed that higher activity resulted from multi-photon excitation of photoactive materials with lower energy photons and utilization of heterojunction to drive electronic processes in the desired direction.…”

Bulk-to-single layer molybdenum disulfide (MoS 2 ) is widely used as a robust candidate for photodegradation of organic pollutants, hydrogen production, and CO 2 reduction. This material features active edge sites and narrow band gap features, which are useful for generating reactive species in aqueous suspensions. However, the high-charge carrier recombination, photocorrosion, unstable sulfide state, and formation of Mo-S-O links during photocatalytic reactions limit its applicability. Thus, research has focused on improving the performance of MoS 2 by tailoring its bulk-to-single layer structure and combining it with other semiconductor materials to improve the photocatalytic performance. Different strategies have been successfully applied to enhance the photocatalytic activity of MoS 2 , including tailoring of the surface morphology, formation of heterojunctions with other semiconductors, doping, and modification with excess sulfur or carbon nanostructures. This review describes the influence of starting precursors, sulfur sources, and synthetic methods to obtain heterostructured morphologies and study their impact on the photocatalytic efficiency. Finally, the relevance of crystal facets and defects in photocatalysis is outlined. Future applications of MoS 2 with tailoring and tuning physicochemical properties are highlighted.
