首次考察了Dawson结构的钨磷酸对乙苯氧化脱氢制苯乙烯的催化行为,并与Keggin结构的钨磷酸进行了对比。结果表明,较短的增活期可能与表面积碳物具有更多的未成对电子有关。
The catalytic behavior of Dawson structure of tungstophosphoric acid to styrene oxidation by dehydrogenation of ethylbenzene was investigated for the first time and compared with the tungstophosphoric acid of Keggin structure. The results show that the shorter activation period may be related to the surface area of carbon with more unpaired electrons.
