摘要

以硝酸钡、钼酸铵及硝酸镁为原料

用半湿法合成了双钙钛矿氧化物Ba

MgWO

用等体积浸渍的方法制备了NiO/Ba

MgWO

光催化剂

并对焙烧前驱体进行了热失重-差热分析

对焙烧制得的样品进行了X射线衍射、扫描电镜分析.通过考察前驱体制备时的pH值对样品光催化活性的影响

和二次焙烧处理对样品性能的影响发现

在前驱体的pH值为8左右时

制得的样品活性最好

样品经1 100 ℃、 6 h二次焙烧处理后

纯度、结晶完整性有所改善

且产氢速率由1.2 μmol/h提高到了1.5 μmol/h.

Abstract

Double perovskite oxide Ba

MgWO

was synthesized by semi-wet method using barium nitrate

ammonium molybdate and magnesium nitrate as raw materials. Photocatalyst NiO/Ba

MgWO

was prepared by equal volume impregnation method. The precursor was analysed by TG-DTA and the calcined sample was characterized by XRD and SEM. The effect of pH in precursor preparation on photocatalytic activity of the sample was investigated

and the effects of the second calcination on performances of the sample were examined. The results show that the prepared samples have best photocatalytic activity at pH=8

the purity and crystal perfection of the sample are improved by the second calcination at 1 100 ℃ for 6 h

and the hydrogen production rate of the c

atalyst increases from 1.2 μmol/h to 1.5 μmol/h.
