Abstract
AbstractThe idea of grid‐scale hydrogen production by water electrolysis has been made possible by developing catalyst‐anchored three‐dimensional (3D) foam‐based electrodes. Catalytic performance in hydrogen and oxygen evolution reactions is improved by incorporating catalyst in 3D interlinked porous architecture, which enhances electrical conductivity and speeds up the discharge of gas bubbles. The detailed study on the role‐play of 3D frameworks in energy generation is explained in this article. The review also focuses on the recent development in utilizing these 3D substrates in the field of electrochemistry. Furthermore, it is imperative to enhance their compatibility with renewable energy systems and high‐temperature electrolysis for the sustainable production of hydrogen. Therefore, this review briefly explores the innovative design of self‐supported 3D framework electrodes using heterostructures and doping techniques to develop stable, durable, and efficient electrocatalysts. These catalysts aim to provide near‐zero overpotential, high selectivity, and long‐term stability for hydrogen production through water electrolysis, paving the way for commercial‐scale green energy production. 3D foam‐based electrodes can emerge as a key technology in the field of electrochemistry.
