本文运用三氧化钨与氯化铵为原料固相合成出ＷＯ２Ｃｌ２，且产率较高，同时可得蓝色氧化钨，并对ＷＯ２Ｃｌ２与蓝色氧化钨的形成机制及ＷＯ２Ｃｌ２的催化活性进行了初步研究．
In this paper, WO2Cl2 was synthesized by the solid state reaction of tungsten trioxide and ammonium chloride, and the yield was high, blue tungsten oxide was obtained at the same time, and the formation mechanism of WO2Cl2 and blue tungsten oxide and the catalytic activity of WO2Cl2 were preliminary studied the study.
