Preparation of Nanosized Mesoporous CuTSPc/SnO2 and Its Photocatalytic Activity under Visible Light Irradiation

Abstract

Abstract: CuTSPc/SnO2 was prepared by a simple template-free hydrothermal method. The i nteraction between CuTSPc and SnO2 was strong by means of sulfonated group. Co mpared with pure SnO2, 0.1 mol%CuTSPc/SnO2 exhibited smaller average pore a nd higher BET surface area. The effects were explained that excellent dispersity and small crystallite size were achieved by the encapsulation of SnO2 with ph thalocyanine.

Key words: copper tetrasulfonated phthalocyanine, tin oxide, mesopore, template-free hydrothermal synthesis, bonding interaction, visible-light photocatalysis
