AI Technical Summary
Existing electrocatalysts exhibit low catalytic activity in the degradation of hexavalent chromium, with low surface adsorption rates and difficulty in recovery. Supported electrocatalytic reaction systems also show low catalytic activity.
NiMo composite electrocatalysts with an array network structure were prepared by hydrothermal synthesis. The nano-NiMo particles were uniformly distributed on the surface of nickel foam. The reaction temperature was controlled at 120~150℃ and the reaction time was controlled at 7~10h to form a high specific surface area and stable catalytic active center.
It improves the electrocatalytic ability of the catalyst, enhances the transport efficiency and stability of hexavalent chromium ions, avoids particle aggregation and stacking, and extends the service life of the catalyst.
