微波水热温度对ZnS纳米晶的结构及其光催化性能的影响
Influence of different temperature on the structure and photocatalytic activity of ZnS nanocrystallites by microwave hydrothermal method
摘要
Abstract
ZnS nanocrystallites were successfully synthesized by microwave hydrothermal method using Zn(NO3 )2 · 6H2 O ,thioacetamide as main raw materials and distilled water as solvent .The phase composition ,morphologies and photocatalytic properties of the as‐pre‐pared samples were characterized by XRD (X‐ray diffractometer) ,SEM (scanning electron microscope) and UV‐2600/2600AUV‐visible spectrometer and the influence of different mi‐crowave hydrothermal temperature on the structure and photocatalytic activity of the prod‐ucts were investigated .Results shows that ZnS nanoparticles with good dispersibility pre‐pared at 170 ℃ has uniform size and exhibite wide band gap energies of 3 .632 eV .Moreover , the as‐prepared ZnS nanoparticles shows high photocatalytic activity to degrade Methyl or‐ange ,which photodegradation efficiency reaches 99 .3% under ultraviolet irradiation for 12 min .关键词
