Microwave synthesis of Zn, Cd binary metal sulfides with superior photocatalytic H2 evolution performance

Zn, Cd bimetallic sulfide (ZnCdS) with fine nanoparticles was prepared with microwave synthesis, and its morphology and structure were analyzed by electron microscope and X-ray diffractometer (XRD). Moreover, the effect of microwave power and microwave time on the photocatalytic H-2 evolution property of ZnCdS was explored. Research results show that the ZnCdS solid solution was obtained by the microwave synthesis method, which shows a good photocatalytic hydrogen evolution property. When the microwave power is 320 W and the microwave time is 20 min, the as-prepared ZnCdS solid solution products have the best photocatalytic H-2 evolution performance, which its value reaches 2031 mu mol/g h.

Automated summary

ZnCdS bimetallic sulfide with fine nanoparticles was successfully synthesized using microwave method, exhibiting excellent photocatalytic hydrogen evolution performance, especially when the microwave power and time are optimized at 320 W and 20 min respectively.
