Microwave Synthesis of Pt Clusters on Black TiO 2 with Abundant Oxygen Vacancies for Efficient Acidic Electrocatalytic Hydrogen Evolution

Abstract Oxygen vacancies‐enriched black TiO 2 is one promising support for enhancing hydrogen evolution reaction (HER). Herein, oxygen vacancies enriched black TiO 2 supported sub‐nanometer Pt clusters (Pt/TiO 2 ‐O V ) with metal support interactions is designed through solvent‐free microwave and following low‐temperature electroless approach for the first time. High‐temperature and strong reductants are not required and then can avoid the aggregation of decorated Pt species. Experimental and theoretical calculation verify that the created oxygen vacancies and Pt clusters exhibit synergistic effects for optimizing the reaction kinetics. Based on it, Pt/TiO 2 ‐O V presents remarkable electrocatalytic…
