Abstract

A cobalt-based amorphous alloy catalytic electrode, which is characterized in that the electrode consists of a grooved electrode frame and a plug-in catalytic electrode plate. The plug-in catalytic electrode plate is made of a sheet of cobalt-based amorphous alloy covered with a metal mesh. Made of particles, the specific composition of cobalt-based amorphous alloy flake particles is Fe35-95 wt%, and the remaining alloy elements are elements that can be electrodeposited together with iron, such as P, Fe, Ni, Cr, Mo, W, Re, etc. A combination of one or more elements; the grooved electrode frame is stamped and formed by a metal sheet. Rectangular holes are evenly provided on both sides of the grooved electrode frame. The metal at the rectangular hole position is punched and bent to make a catalytic converter. Fixing plate for electrodes.

Description

technical field [0001] The invention relates to a catalytic electrode in the field of electrochemistry, in particular to a cobalt-based amorphous alloy composite catalytic electrode and a production method. Background technique [0002] Amorphous alloys have the following characteristics: ①Amorphous alloys can be made into samples of various compositions in a wide range, so that their electronic properties can be adjusted in a wide range; ②The catalytic active center can be a single The form is evenly distributed in a chemically uniform environment; ③The surface of the amorphous alloy has a high concentration of unsaturated centers, and the coordination number of the unsaturated centers has a certain range, so its catalytic activity and selectivity are generally better than those of the corresponding 4. The non-porosity of its surface is that it gets rid of the problem that the diffusion of reactive species in the presence of multiple catalysts affects the surface reaction. ...
