Hexadecyltrimethylammonium hydroxide promotes electrocatalytic activity for the oxygen evolution reaction.

ABSTRACT: The oxygen evolution reaction is an essential factor in many renewable energy technologies, such as water splitting, fuel cells, and metal-air batteries. Here we show a unique solution to improve the oxygen evolution reaction rate by adjusting the electrolyte composition via the introduction of hexadecyltrimethylammonium hydroxide into an alkaline electrolyte. The strong adsorption of hexadecyltrimethylammonium cations on the surface of electrocatalysts provides the increased absolute number of OH^- ions near the electrocatalyst surface, which effectively promotes the oxygen evolution reaction performance of electrocatalysts, such as Fe_1-yNi_yS₂@Fe_1-xNi_xOOH microplatelets and SrBaNi₂Fe₁₂O₂₂ pow
