“…SBA-15 silica was synthesized for hydrogenation of alkylanthraquinone by adding normal paraffin and alkyl benzene as swelling agents and using a low-temperature gelation procedure [8]. Solar energy contains huge amounts of energy, and most of the energy required by humans comes directly or indirectly from the sun [9]. However, thus far, the human conversion and utilization efficiency of solar energy remain at extremely low levels [10,11].…”

Metal-organic frameworks (MOFs) and layered double hydroxides (LDHs) have been considered to be one of the most promising and worthy hot spot materials to develop advanced catalysts for efficient hydrogen evolution due to their prominent characteristics, including unique structures, environmentally friendly nature, high redox activities, and homogeneously effective utilization of transition metal atoms. In this work, the delicate S-scheme heterojunction photocatalyst, CoAl LDH@ Ni-MOF-74, was rationally designed and successfully constructed by coupling Ni-MOF-74 with CoAl LDH based on their peculiar structure, excellent electronic properties, and opposite surface potential for enhancing hydrogen generation activity under visible light irradiation. The CoAl LDH nanolayers evenly and dispersedly load on the surface of Ni-MOF-74. The CoAl LDH@Ni-MOF-74 exhibited higher photocatalytic hydrogen evolution activity compared with Ni-MOF-74 and CoAl LDH alone, mainly because the formation of the CoAl LDH@Ni-MOF-74 S-scheme heterojunction accelerated the recombination of several electrons (from conduction band (CB) of Ni-MOF-74) and holes (from valence band (VB) of CoAl LDH) and prevented the recombination of other electrons (from CB of CoAl LDH) and holes (from VB of Ni-MOF-74).

To deal with the energy crisis brought by economic development and solve the traditional situation where only fossil fuels can be used, we prepared S-scheme heterojunction composite photocatalyst W 18 O 49 /Mn 0.2 Cd 0.8 S for photocatalytic hydrogen production by Physical stirring method. The hydrogen production performance of composite photocatalyst W 18 O 49 /Mn 0.2 Cd 0.8 S in visible light is evaluated by a series of photocatalytic analysis and characterization methods. The results showed that the hydrogen production activity was the highest when the load ratio of W 18 O 49 was 5 %, and the hydrogen production amount reached 268.65 μmol (5373 μmol h À 1 g À 1 ) for 5 h, which was 2.96 times of the hydrogen production amount of pure Mn 0.2 Cd 0.8 S (90.76 μmol). The results show that the improvement of hydrogen production performance is mainly due to the formation of S-scheme heterojunction between W 18 O 49 and Mn 0.2 Cd 0.8 S contact interface, which promotes the consumption of ineffective electrons and holes, increases the rate of charge separation and transfer, reduces the activation energy of the catalytic reaction system, and enhances the performance of photocatalytic hydrogen production. The successful completion of this work provides a new idea for the modification of Mn 0.2 Cd 0.8 S semiconductor material and improves its application in photocatalytic hydrogen production.

“…Besides TiO 2 , it was worth noting that CeVO 4 also revealed superior photocatalytic performance after coupling with CoP. [131] CeVO 4 firmly anchored on the surface of ZIF-9 derived CoP, and the internal electric field formed between these two Furthermore, in the NiO/g-C 3 N 4 photocatalytic system, when NiO and g-C 3 N 4 contacted, in order to reach the Fermi energy level equilibrium state, electrons would transfer from g-C 3 N 4 with higher Fermi energy level to NiO, which would lead to the band bending of NiO and g-C 3 N 4 and the formation of an internal electric field (from g-C 3 N 4 to NiO). Under the effect of the p-n junction, the holes in the VB of g-C 3 N 4 could transfer to NiO rapidly, while the electrons on the CB migrated to Ni 2 P through the intimate interfacial contact and then participated in the hydrogen production reaction.…”

Photocatalytic hydrogen evolution can effectively alleviate the troublesome global energy crisis by converting solar energy into the chemical energy of hydrogen. In order to realize efficient hydrogen generation, a variety of semiconductor materials have been extensively investigated, including TiO2, CdS, g‐C3N4, metal‐organic frameworks (MOFs), and others. In recent years, to achieve higher photocatalytic performance and reach the level of large‐scale industrial applications, photocatalysts decorated with transition metal phosphides (TMPs) have shone brightly because of their low cost, stable physical and chemical properties, and substitution for precious metals of TMPs. This Review highlights the preparation methods and properties associated with photocatalysis of TMPs. Moreover, the H2 generation efficiency of photocatalysts loaded with TMPs and the roles of TMPs in catalytic systems are also studied systematically. Apart from being co‐catalysts, several TMPs can also serve as host catalysts to boost the activity of photocatalytic composites. Finally, the development prospects and challenges of TMPs are put forward, which is valuable for future researchers to expand the application of TMPs in photocatalytic directions and to develop more active photocatalytic systems.
