What is Design and synthesis of ZnCo2O4/CdS for substantially improved photocatalytic hydrogen production about?

In this study, the hydrogen evolution performance of CdS nanorods is improved using ZnCo 2 O 4 . ZnCo 2 O 4 nanospheres are synthesized using the hydrothermal and calcination methods, and CdS nanorods are synthesized using the solvothermal method. From the perspective of morphology, numerous CdS nanorods are anchored on the ZnCo 2 O 4 microspheres. According to the experimental results of photocatalytic hydrogen evolution, the final hydrogen evolution capacity of 7417.5 μmol•g -1 •h -1 is slightly more than two times that of the single CdS, which proves the feasibility of our study. Through various characterization methods, it is proved that the composite sample has suitable optoelectronic properties. In addition, ZnCo 2 O 4 itself exhibits good conductivity and low impedance, which shortens the charge-transfer path. Overall, the introduction of ZnCo 2 O 4 expands the adsorption range of light and improves the performance of photocatalytic hydrogen evolution. This design can provide reference for developing high-efficiency photocatalysts.Keywords ZnCo 2 O 4 nanosphere, CdS nanorods, photocatalytic hydrogen evolution
