Cellulose/SnS2 composite with enhanced visible-light photocatalytic activity prepared by microwave-assisted ionic liquid method

摘要

A facile method was used to synthesize cellulose/SnS2 composites (CE/SnS2 ) by a microwave-assisted ionic liquid (MAIL) method. The effects of ionic liquid types on the structure and properties of SnS2 samples were investiga ted. Results showed that the ionic liquid played an important role in the control over the morphology, size and photocatalytic performance of the SnS2 particles. The as-synthesized CE/SnS2 composites were systematically investigated by XRD, SEM, TEM, BET, XPS, UV-visible and PL. It was demonstrated that the obtained CE/SnS2 composites showed three dimensio nal architecture and excellent visible-light photocatalytic activity asphotocata lyst for RhB degradation. The superior visible-light photocatalytic performac es for composites were ascribed to their composite structure and the synergi stic effects between flower-like SnS2 and cellulose.
