A hybrid of CdS/HCa2Nb3O10 ultrathin nanosheets for promoting photocatalytic hydrogen evolution

Abstract

A hybrid of CdS/HCa2Nb3O10 ultrathin nanosheets was synthesized successfully through a multistep approach. The structures, constitutions, morphologies and special surface areas of the obtained CdS/HCa2Nb3O10 were characterized well by XRD, XPS, TEM/HRTEM and BET, respectively. TEM and BET results demonstrated the unique structural features of CdS/HCa2Nb3O10 restrained the aggregation of CdS nanoparticles as well as the restacking of nanosheets effectively. HRTEM showed CdS nanocrystals about 25~30 nm were firmly anchored on HCa2Nb3O10 nanosheets and an tough heterointerface between CdS and nanosheet was formed. Efficient interfacial charge transfer from CdS to HCa2Nb3O10 nanosheet was also confirmed by EPR and photocurrent response. The photocatalytic activity tests (λ>400 nm) showed that the optimal hydrogen evolution activity over CdS/HCa2Nb3O10 with was about 4 times that of the bare CdS, because of the efficient separation of photo-generated carriers.
