Research on Electrocatalytic Hydrogen Evolution Reaction Performance of Pt-P25 Prepared by Critical Point Drier

Abstract

Abstract: Among various hydrogen production processes, electrochemical water splitting is an important way to obtain hydrogen energy, and Pt is the most ideal catalyst for the hydrogen evolution reaction (HER). Nevertheless, large-scale application of Pt-based materials in HER are limited due to their scarcity and high cost, there is an urgent need to develop a low content and efficient platinum catalyst. P25 is a kind of hybrid titanium dioxide with high lattice defect density and high current carrier concentration, which has good catalytic effect. Commercially available mixed crystal TiO₂ (P25) as catalysts supported Pt (Pt-P25) were prepared by a critical point drier, the structure and morphology of catalysts were analyzed by XRD、TEM and XPS, and the electro-catalytic HER performance of Pt-P25 were explored in different critical point drying conditions. The results show that TiO₂ supported Pt atom cluster is successfully prepared by the critical point drying method. Under certain conditions, electro-catalytic HER of Pt-P25 is the best when carbon dioxide intake rate is slow, exchange rate is 7, and outlet gas heating rate is med.
