Removal of Total Organic Carbon from Aqueous Phenol Solution Using Photocatalytic ZnO Nanopowders Prepared by Solution Combustion Method

Abstract:

ZnO nanopowders were prepared by Solution Combustion Method (SCM). The ZnO nanopowders synthesized using Zn(OH)2 and glycine as an oxidant and a fuel (with fuel/ oxidant ratio, F/O=0.8), showed excellent crystalline and photocatalytic characteristics. To confirm photocatalytic activities of the prepared ZnO powder, total organic carbon (TOC) was tried to remove from aqueous phenol solution. Surprisingly, SCM ZnO nanopowder shows 1.6 fold higher destruction rates of the organic pollutant than P-25 TiO2 nanopowder which is known as a kind of standard photocatalyst.
