以 Sol- Gel法制备的、表面积和孔径相近的含水 Mo O3 / Ti O2 、WO3 / Ti O2 为催化剂 ,光催化分子氧氧化甲烷 .初步研究表明 ,催化剂的活性高于 Ti O2 ,且有少量的甲醇生成 .
MoO3 / Ti O2 and WO3 / Ti O2, which are prepared by Sol-Gel method and have similar surface area and pore size, are used as photocatalysts to oxidize methane with molecular oxygen.It has been found that the activity of the catalyst is higher than that of Ti O2 and a small amount of Methanol production.
