This invention provides a NiO x A method for preparing a Ni(OH)₂ / NF supported
palladium nanoparticle catalyst includes the following steps:
Nickel foam (NF) is sequentially placed in
hydrochloric acid solution,
acetone solution, and deionized water, ultrasonicated, and dried to obtain pretreated NF;
Nickel nitrate hexahydrate and
hexamethylenetetramine are dissolved in deionized water, ultrasonicated until a homogeneous solution is formed, poured into a high-
pressure reactor, and the pretreated NF is vertically immersed into the homogeneous solution, sealed, and subjected to a
hydrothermal reaction. After removal, it is washed and dried to obtain a Ni(OH)₂ / NF intermediate with an ultrathin array of
nickel hydroxide nanosheets; The obtained Ni(OH)₂ / NF intermediate is placed in a
tube furnace and sintered under
nitrogen conditions to obtain NiO with a porous array of
nickel oxide nanosheets. x / NF precursor. The obtained NiO x The / NF precursor was placed in a
palladium salt solution and reacted at a constant temperature. After removal, it was washed and dried to finally obtain NiO. x / NF supported
palladium nanoparticle catalyst. This application also discloses a NiO x / NF supported palladium
nanoparticle catalyst and its electrocatalytic method for PET plastics.
