Preparation and properties of a novel three dimensional network structure FeCoNi three element alloy for hydrogen production

Abstract

The experimental study was made on the preparation of a new three-dimensional network structure of FeCoNi three alloy catalyst for hydrogen production and the performance of the catalyst in the process of hydrogen production. In order to find out the optimal electroplating conditions, the effects of different plating solution temperature, current density, plating time and plating solution concentration on the catalyst preparation were studied. Through the experiment find that when the electroplating solution concentration of CoCl2 is 40g / L, FeSO4 concentration is 30g / L, the concentration of NiCl2 is 20g / L, the concentration of H3BO3 is 30g / L, electroplating environment for 20 minutes of electroplating time, 40℃ temperature of the electroplating solution, 1.0A /cm2 current density, the hydrogen result is the best.
