SiO〓 crystal transformation was improved by adding Na〓SO〓, alpha cristobalite but not tridymite was catalytic active support. C〓 selectivity was improved by adding W and P, and suppressed deep oxidation property of SiO〓. W-O in catalyst surface was not active species. The support combined with S, W, P show low activity and high C〓 selectivity.

Na〓SO〓的加入促进了SiO〓晶型的转化，α-方石英是催化活性载体成分，而鳞石英没有甲烷氧化偶联反应活性。W和P的加入改善了C〓烃的选择性，抑制了SiO〓的深度氧化特性；W-O物种不是催化活性物种；由S、W、P及SiO〓组成的载体反应活性较差，但选择性较好；同时S元素对C〓烃的选择性的贡献有限。
