Abstract

A series of unique morphologies of ZnO were synthesized by a simple mild solvothermal process using equimolar of Zn(NO3)2/Zn(AC) 2-hexamethylenetetramine (HMT) acting as precursors and ethylene glycol (EG) and triethylamine (TEA) as the dispersant and surfactant additive, respectively. When the as-prepared particles were further treated in 0.02 M HMT solution for such a long time as 72 h, screw-like and rose-like crystals with three-dimensional and developed structure could be formed. The deNOx photocatalytic activity was characterized and the analysis results showed that the modified ZnO crystals possessed a three-dimensionally developed structure and had higher deNO photocatalytic activity compared to that of the as-prepared untreated ZnO.
