非贵金属 meaning in Chinese
base metal
non-noble metal
Examples
- Study of temperature rising behavior and catalytic activity of non - noble metal oxides for oil fume purification under microwave irradiation
微波场下非贵金属氧化物的升温行为和烹饪油烟的催化净化性能研究 - Other work has concentrated on materials ranging from nonprecious metal catalysts such as cobalt and chromium to catalysts consisting of fine dispersions of particles embedded in porous composite structures
其他研究工作则著重于别的材料，涵盖钴或铬等非贵金属，以及成份为嵌于多孔复合物结构中的微小颗粒的触媒。 - Catalysts were prepared by impregnation reduction , thermal reduction , advanced thermal reduction and sol - gel methods from these metals . electrochemistry measurements , xrd , tem were used to test these catalysts . the results showed that these metals have some electrocatalysis activities towards hydrogen oxidation reaction
本文选择了w 、 mo 、 co等金属,采用浸渍还原法、热还原法、改进的热还原法以及溶胶凝胶法分别制备了这几种金属的碳载催化剂,对制备出的非贵金属催化剂进行了电化学测试、 x -射线衍射( x - raydiffraction , xrd ) 、透射电子显微镜( transmissionelectronmicroscopy , tem )等测试,研究结果表明:这些非贵金属在硫酸体系中对氢气的氧化反应均有一定的催化活性。
