摘要
采用水热法,以NaCl为引导剂,调节不同的pH值得到形貌均一的纺锤形和花球形WO_3材料。采用XRD、SEM、TEM和Raman光谱研究了WO_3的形貌和结构,同时研究了不同形貌和不同退火条件下样品的太阳光催化降解罗丹明B的性能。研究发现,纺锤形WO_3具有更好的光催化降解罗丹明B的性能,纺锤形WO_3的光催化性能受其微观结构影响较大。
The uniform spindle-like and flower-like WO_3 were synthesized via a simple hydrothermal method by using Na Cl as capping agent and adjusting the p H. The structure and morphology of WO_3 were investigated by XRD, SEM, TEM and Raman spectroscopy. It is found that the spindle WO_3 has better photocatalytic properties for degradating Rhodamine B under sunlight and the photocatalytic properties of WO_3 are sensitive to microstructure.
