of 3.00-0.01 V at room temperature. 3 Results and discussion The CoO/graphene composites were prepared under an ultrasonic condition at room temperature (see Fig. 1). Here, we used the metal carboxylic Co4(CO)12 cluster as the precursors. Firstly, Co4(CO)12 cluster can be readily decomposed to metals Co and CO, as shown in reaction 1. Secondly, the active metal Co can be oxidized rapidly to CoO......

Influence of Ga and Hg on microstructure and electrochemical corrosion behavior of Mg alloy anode materials FENG Yan(冯 艳), WANG Ri-chu(王日初), YU Kun(余 琨), PENG Chao-Qun(彭超群), LI Wen-xian(黎文献... and Ga was put forward. Magnesium atoms are dissolved in liquid Hg and Ga to form amalgam and undergo severe oxidation at the amalgam/electrolyte interface. Key words: Mg alloy anode......
Recovery of valuable metals from anode material of hydrogen-nickel battery WU Fang(吴 芳), XU Sheng-ming(徐盛明), LI Lin-yan(李林艳), CHEN Song-zhe(陈崧哲), XU Gang(徐 刚), XU Jing-ming(徐景明... the anode material of hydrogen-nickel battery was performed through a hydrometallurgical process. Most of rare earth elements are separated from nickel and cobalt in the form of sulfates when the anode......

titanium anodes on methanol Abstract: Modified titanium-based metal anode was prepared by thermal decomposition method and its electrocatalysis for methanol was measured... of SnSb coating is able to improve the electrocatalytic activity evidently. But after some Ru is added into the anodic coating, the electrocatalytic activity of modified anode was degraded because element......

Metal Dusting-Mechanisms and Preventions () 摘要:Metal dusting attacks iron, low and high alloy steels and nickel-or cobalt-base alloys by disintegrating bulk metals and alloys into metal particles... mechanism is still not well understood. Current methods of protection against metal dusting are either directed to the process conditions-temperature and gas composition-or to the development of a dense......
