Catalyst durability in electrocatalytic HO production: key factors and challenges.

On-demand electrocatalytic hydrogen peroxide (HO) production is a significant technological advancement that offers a promising alternative to the traditional anthraquinone process. This approach leverages electrocatalysts for the selective reduction of oxygen through a two-electron transfer mechanism (ORR-2e), holding great promise for delivering a sustainable and economically efficient means of HO production. However, the harsh operating conditions during the electrochemical HO production lead to the degradation of both structural integrity and catalytic efficacy in these materials.
