“…CuInS 2 produced 84.0 μmol/h of H 2 and presented at the same time high stability. CuInS 2 quantum dots dispersed in aqueous media through the aid of a multidentate ligand and Ru as co‐catalyst presented high H 2 production rates (418 μmol h −1 , apparent quantum efficiency of 4.7 %) under pure visible light irradiation .

Problems derived from climate change dictate the reestablishment of our prospective in energy production. In this direction, converting solar energy through photocatalysis into suitable fuels such as hydrogen and carbon‐based fuels by water splitting and CO2 reduction, respectively, has been established as a promising approach. Currently, the main concern in this field is the development of cost‐effective and efficient photocatalysts. Among the different systems studied, Cu‐based photocatalysts are considered attractive candidates for both applications due to their relative low‐cost, the natural abundance of the constituents and their promising reactivity. In this review, the current progress in the field of Cu‐based photoactive materials for both H2 production and CO2 reduction will be discussed. Finally, an outlook on the challenges and future research directions is given.

“…To make powdered photocatalytic water‐splitting sustainable, a visible‐light sensitive material capable of splitting water into H 2 and O 2 is critical. Numerous studies have reported metal‐containing photocatalysts with high activity for H 2 or O 2 evolution from water decomposition under visible‐light irradiation, but most only executed water‐splitting half‐reactions with sacrificial reagents . Domen et al developed Rh 2‐y Cr y O 3 /GaN:ZnO compounds, which contain noble metals and are so far the most active catalysts for overall water‐splitting under visible light irradiation .…”

Nitrogen-doped graphene oxide quantum dots exhibit both p- and n-type conductivities and catalyze overall water-splitting under visible-light irradiation. The quantum dots contain p-n type photochemical diodes, in which the carbon sp(2) clusters serve as the interfacial junction. The active sites for H2 and O2 evolution are the p- and n-domains, respectively, and the reaction mimics biological photosynthesis.

“…[104] In 2013, Teng et al tried CuInS 2 QDs for photocatalytic hydrogen evolution. [105] The as-prepared CuInS 2 QDs had a size about 4.3 nm and a bandgap of 1.97 eV with its conduction band located at À 1.2 V (vs. NHE), which made it thermodynamics feasible for hydrogen evolution. After photodeposition of Ru on the surface, 4.7 % apparent quantum yield was achieved.…”

Photocatalytic production of hydrogen from water can directly convert solar energy into chemical energy storage, which has significant advantages and great promise. As an emerging photosensitizer, the efficiency of quantum dots (QDs) based artificial photosynthetic system have made breakthroughs. In this review, we will give a summary of the development of QDs based photocatalytic hydrogen evolution in these years. First, we highlight different types of hydrogen evolution catalyst combined with QDs; then we focus on the surface modification and heterostructure formation of QDs to improve the photocatalytic efficiency, respectively. In the end, we will propose some Cd‐free QDs and future development of photocatalytic hydrogen evolution.
