The present disclosure is directed to providing stable highly active catalysts for use in production of hydrogen from water.

Catalytic structures and methods of generating hydrogen gas

The catalytic composition for the electrochemical reduction of carbon dioxide is a metal oxide supported by multi-walled carbon nanotubes. The metal oxide may be nickel oxide (NiO) or tin dioxide (SnO). The metal oxides form 20 wt % of the catalyst. In order to make the catalysts, a metal oxide precursor is first dissolved in deionized water to form a metal oxide precursor solution. The metal oxide precursor solution is then sonicated and the solution is impregnated in a support material composed of multi-walled carbon nanotubes to form a slurry. The slurry is then sonicated to form a homogeneous solid solution. Solids are removed from the homogeneous solid solution and dried in an oven for about 24 hours at a temperature of about 110&#xb0; C. Drying is then followed by calcination in a tubular furnace under an argon atmosphere for about three hours at a temperature of 450&#xb0; C.
