SnO2 is an n-type semiconductor,which has been investigated intensively in history as gas sensing materials.Over recent years,its catalytic properties have attracted much attention,due to its structur
The effect of heat treatment on the Co-N-C/SiO2catalysts prepared through supported metalloporphyrin has been investigated for selective oxidation of ethylbenzene.And techniques such as BET,XRD,FT-IR,
Methanol-to-olefins (MTO) conversion is one of the important processes in coal chemical industry.By extensive density functional theory calculations,we have proved that the MTO conversion proceeds thr
