查询词典 tris nitro-methane

The experimental results show that Mn2O3 was main active species and addition of Zr further activated methane molecules to improve methane conversion; C2 selectivity was improved by adding W and P, and suppressed deep oxidation property of SiO2; W–O in catalyst surface was not active species.

通过选取五组该催化剂对其进行XRD、XPS、FT-IR以及SEM表征，表明Mn2O3和Na2Zr(PO4)2是多组分甲烷氧化偶联催化剂的活性组分，且Mn2O3起主要作用，Zr的加入进一步活化了甲烷分子，提高了甲烷的转化率，W和P的加入改善了C2烃的选择性，抑制了SiO2的深度氧化特性；W–O物种不是催化活性物种。
