Cr_2O_3, a poisonous metallic oxide, is usually used as one of the most important catalyst promoter for CO shift reaction. 氧化铬属剧毒物质,至今仍是一氧化碳变换催化剂的重要助剂。
Ni Mo bi metallic oxide catalyst prepared by a sol gel method has been used to synthesize high quality multi walled carbon nanotube bundles with high purity by catalytic decomposition of CH4. The experiment reveals that the prepared catalysts have high activity and high efficiency. 采用溶胶凝胶法合成的Ni-Mo双金属氧化物催化剂,用CVD法催化裂解甲烷从而大量制备高质量高纯度的成束多壁纳米碳管。
