Raney nickel dispresion - plated low hydrogen overvoltage cathode

摘要

Durable low hydrogen overvoltage cathodes have been developed for chlor-alkali processes. The cathodes are made by dispersion-plating a novel hydrogen storing alloy with Raney nickel on a variety of substrates. The cathodes exhibit low hydrogen overvoltages (80-100 mV at 30 A dm~(-2) in a 35 wt
