Nickel hydroxide as a non-noble metal co-catalyst decorated on Cd0.5Zn0.5S solid solution for enhanced hydrogen evolution

“…Xue et al constructed 2D mesoporous ultrathin Cd 0.5 Zn 0.5 S nanosheets, and the hydrogen evolution rate was 2.2 times higher than that of Cd 0.5 Zn 0.5 S nanoparticles. 27 Zhang et al reported a NiSe 2 /Cd 0.5 Zn 0.5 S type-II heterojunction whose photocatalytic hydrogen evolution rate was approximately 2.1 times that of pristine Cd 0.5 Zn 0.5 S. 28 Other works, such as those investigating Co 2 P/Cd 0.5 Zn 0.5 S, 29 ZIF-8/Cd 0.5 Zn 0.5 S, 30 Bi 2 S 3 /Cd 0.5 Zn 0.5 S, 31 and g-C 3 N 4 /Cd 0.5 Zn 0.5 S, 32 showed the feasibility of facilitating photogenerated electron migration. However, work on co-catalyst-modified Cd 0.5 Zn 0.5 S is relatively lacking.…”

Amorphous CoSx decorated Cd0.5Zn0.5S with a bulk-twinned homojunction for efficient photocatalytic hydrogen evolution

“…In addition, the 4 wt% CoS x /T-CZS composite has good photostability for photocatalytic H 2 evolution from data shown for the cycling experiments in Fig. S3 † 35,61,62 . The XRD analysis shows that the crystal structure of the used sample is almost consistent with that of the fresh sample (Fig.…”

Lattice-Matched CoP/CoS2 Heterostructure Cocatalyst to Boost Photocatalytic H2 Generation

“…The global shortage of fossil fuels and the environmental pollution have resulted in growing demand for clean and renewable energy. − As a clean fuel, hydrogen has a high energy density and causes zero pollution, so it is recognized as a key environmentally friendly energy source. − Among the sustainable strategies to produce H 2 via the conversion of solar energy, semiconductor-based photocatalytic water splitting techniques have attracted widespread attention. , Nevertheless, the solar-to-H 2 conversion efficiency is still low because of fast charge-carrier recombination. , Recently, it is reported that functionalized cocatalysts can be integrated with the semiconductor and act as active catalytic centers. In addition, the cocatalyst can form Schottky junctions with the semiconductor, thus achieving the directional transfer of photogenerated electrons, which is quite helpful for promoting the efficiency of the photocatalytic hydrogen evolution reaction (HER). − …”
