▎ 摘　　要

NOVELTY - Nickel phosphide graphene aerogel composite material involves dissolving nickel nitrate in de-ionized water, stirring, adding sodium alginate, ultrasonic dispersion, forming hydrogel after allowing to set with deionized water and ethanol, freeze drying and high temperature phosphating with red phosphorus in a tube furnace. USE - Nickel phosphide graphene aerogel composite material used for generating hydrogen. ADVANTAGE - Process is environment-friendly, low cost and simple, thus allowing for large-scale industrial production. Its pore structure improves the electron transfer rate, thus improving the electrochemical hydrogen separation performance. DESCRIPTION OF DRAWING(S) - The drawing is a linear scan voltammogram of the acidic solution containing nickel phosphide.
