Abstract

The invention discloses a nickel and molybdenum alloy electrode material which comprises 30-80% of Ni and 10-60% of Mo and further comprises 0.1-10% of Fe, Cr, W, Co, Mn and V. The preparation method of the electrode material comprises the following steps: drying a raw material after washing the same; placing dried Ni and Mo in a vacuum induction melting furnace to perform smelting at 10-30 kW; introducing argon into the vacuum induction melting furnace which smelts Ni and Mo; vacuumizing the vacuum induction melting furnace which smelts Ni and Mo; adding dried Fe, Cr, W, Co, Mn and V into the vacuumized vacuum induction melting furnace and heating the vacuum induction melting furnace in sequence at 10-30 kW and 30-60 kW; refining the melted material; and taking out the vacuum cooled material to obtain the nickel and molybdenum alloy electrode material. The preparation method is easy to operate, safe and reliable, short in production period and low in cost.

Description

technical field

[0001] The invention belongs to the technical field of electrode materials, and in particular relates to a nickel-molybdenum alloy electrode material and a preparation method thereof. Background technique

[0002] Hydrogen energy, as a clean, efficient, pollution-free, high combustion calorific value of new energy, is one of the current research hotspots of new energy. Common hydrogen production methods include fossil fuel hydrogen production, biomass as raw material hydrogen production, and water decomposition hydrogen production. The most mature and economical method, and has the advantages of simple operation and high product purity. The current problem of electrolytic hydrogen production technology is the high hydrogen evolution overpotential and high energy consumption in the electrolysis process. Therefore, the development of electrode materials with low hydrogen evolution overpotential, low energy consumption and high activity has become an urgent pro...
