摘 要: 分别以水热法和醇热法制备沸石咪唑类框架8(zeolitic imidazolate framework 8,ZIF8),并以ZIF8为载体,负载贵金属Ag和Au,复合材料表现出基于表面等离子体共振效应的光催化活性。但是贵金属的负载量和光催化活性不是线性关系,可能是由于过量的Ag会成为电子捕获中心,从而使光催化活性降低。
关 键 词: 催化化学;沸石咪唑类框架8;表面等离子体共振效应;光催化
Title: Synthesis of Ag and Au loaded ZIF8 and research on its photocatalytic activity

Abstract: In this work, the synthesis of zeolitic imidazolate framework 8 (ZIF8) was reported using hydrothermal and alcohothermal methods, respectively. Based on the prepared ZIF8, Ag or Au was loaded. The composite Ag/ZIF8 exhibited enhanced photocatalytic activity due to surface plasmon resonance effect. However, the photocatalytic activity was not linear to the amount of loaded Ag. This might be due to the fact that excess Ag acts as electron trapper, which had a negative effect on the photocatalytic activity.
Key words: catalysis chemistry; zeolitic imidazolate framework 8; surface plasmon resonance effect; photocatalysis
