摘要
选取了前期合成的三维开放骨架硼钒酸盐[Zn6(en)3][(V^ⅣO)6(V^ⅤO)6 O6(B18O36(OH)6)·(H2O)]2·14H2O(1)为目标晶体,将其作为光催化剂用于光催化降解MB和RhB。实验结果表明,目标催化剂具有选择性光催化降解MB的能力,当光催化反应进行到120 min时,MB的去除率可达到92.5%。
Borovanadate is a new type of polyoxometalate.It combines the structural characteristics of vanadate and borate.Its diversified structure and variable vanadium valence give it a more diverse structure and potential application value.In recent years,great progress has been made in the synthesis of borovanadates,but few investigation on their capability and application has been conducted up to now.In this paper,[Zn6(en)3][(VⅣO)6(VⅤO)6 O6(B18 O36(OH)6)·(H2 O)]2·14 H2 O(1)as a three-dimensional open-framework zinc borovanadate prepared by early work was selected as the target crystal and used as photocatalyst for photocatalytic degradation of MB and RhB.Photocatalytic experiments showed that compound 1 had the ability of selective photocatalytic degradation of MB.Under UV light for 2 h,the removal rate of MB could reach 92.5%.
