摘要：ZnWO4/CdWO4 core-shell structured nanorods had been synthesized by a simple refluxing method under mild conditions in which the crystallization event of ZnWO4 happened on the backbone of CdWO4 single crystalline nanorods in a ligand-free system. CdWO4 nanorod-directed oriented attachment mechanism had been clearly observed for the formation of ZnWO4/CdWO4 core-shell structured nanorods. The size of ZnWO4 could be tuned by changing the molar ratio of Zn source and Cd source. The photocatalytic activity of ZnWO4/CdWO4 core-shell structured nanorods was much better than CdWO4. The enhancement in photocatalysis performance was demonstrated to be the match of lattice and energy level between the ZnWO4 and CdWO4. This match facilitated the separation and transfer of photogenerated e–/h+ pairs at the heterojunction interfaces and might be important for other heterostructured materials. Kinetic studies using radical scavenger technologies suggested that photogenerated holes were the dominant photooxidants.
