Abstract
A catalyst includes a graphite substrate and a thin film of copper-palladium alloy disposed on the graphite substrate. The copper-palladium alloy conforms to a formula of Cu1-xPdx, where x is about 0.4. The thin film includes conical structures that has a length of 1-20 μm, and the conical structures having a pine-tree shape has tiers of sheet-like branches. An electrode includes the catalyst and no binder.

A catalyst, comprising:
- a graphite substrate;
- and
- a thin film of copper-palladium alloy disposed on the graphite substrate, wherein the copper-palladium alloy conforms to a formula of Cu1-xPdx, where x is about 0.4,
- the thin film includes conical structures that have a length of 1-20 μm, and
- the conical structures have a pine-tree shape that has tiers of sheet-like branches.

A method of preparing a catalyst, comprising:
- executing an aerosol-assisted chemical vapor deposition (AACVD) process that comprises:
- converting a precursor solution into an aerosol mist by an ultrasonic humidifier, the precursor solution comprising copper acetylacetonate and palladium acetylacetonate,
- directing the aerosol mist towards a graphite substrate placed in a furnace by a carrier gas containing hydrogen and nitrogen, and
- maintaining the graphite substrate at a temperature of 450° C.-550° C. so as to evaporate a solvent of the aerosol mist, decompose the copper acetylacetonate and the palladium acetylacetonate, and form a thin film of copper-palladium alloy on the graphite substrate to form a catalyst including the thin film and the graphite substrate;
- and
- using the catalyst directly as an electrode without binding to another support surface or electrode surface.
