Abstract: Disclosed herein are trimetallic PtAu-based nanocatalysts for electrochemical hydrogen production and screening methods thereof. Nanocatalysts are produced through a polymer pen lithography (PPL) technique, which enables large-scale fabrication of nanoparticle arrays with programmable specifications such as size, shape, and composition, providing a route to the high-throughput screening and discovery of new catalysts.

Abstract: Methods of catalyzing an electrochemical reaction are provided. In embodiments, such a method comprises applying an electrical potential across a fixed working electrode and a counter electrode, the fixed working electrode and the counter electrode in contact with an electrolyte solution comprising reactant species and fluidized electrocatalyst particles, the fluidized electrocatalyst particles undergoing free fluid motion within and throughout the electrolyte solution, wherein the electrical potential is applied to induce an electrochemical reaction between the reactant species and the fluidized electrocatalyst particles at transient interfaces formed between the reactant species, the fluidized electrocatalyst particles and the working electrode upon collisions of the fluidized electrocatalyst particles with the working electrode.
