NOVELTY - Preparation of graphene oxide-loaded ruthenium-doped cobalt phosphide based aerogel involves (s1) dispersing a powdered ruthenium-doped cobalt phosphide-graphene oxide composite material in water, adding chitosan, and dispersing uniformly to obtain a solution (A), and (s2) dispersing graphene oxide in water to obtain a solution (B), uniformly mixing the solution (A) and solution (B), adding acetic acid, removing bubbles, leaving still and drying. The weight ratio of the powdered composite material, chitosan and graphene oxide is 1:3-10:0.04-0.2. The concentrations of the powdered composite material and chitosan in solution (A) are 0.5-2 wt.% and 3-10 wt.% respectively. The concentration of the graphene oxide in solution (B) is 0.1-0.5 wt.%. USE - Preparation of graphene oxide-loaded ruthenium-doped cobalt phosphide based aerogel used in preparing catalyst for hydrogen evolution from hydrolysis of metal hydrides (all claimed). ADVANTAGE - The aerogel can be repeatedly used, has a high hydrogen evolution rate on metal hydride hydrolysis and is good in stability.
