Intensifying Hydrogen Spillover for Boosting Electrocatalytic Hydrogen Evolution Reaction

Abstract

Hydrogen spillover has attracted increasing interests in the field of electrocatalytic hydrogen evolution reaction (HER) in recent years because of their distinct reaction mechanism and beneficial terms for simultaneously weakening the strong hydrogen adsorption on metal and strengthening the weak hydrogen adsorption on support. By taking advantageous merits of efficient hydrogen transfer, hydrogen spillover-based binary catalysts have been widely investigated, which paves a new way for boosting the development of hydrogen production by water electrolysis. In this paper, we summarize the recent progress of this interesting field by focusing on the advanced strategies for intensifying the hydrogen spillover towards HER. In addition, the challenging issues and some perspective insights in the future development of hydrogen spillover-based electrocatalysts are also systematically discussed.

Dual-cation doping precisely reducing the energy barrier of the rate-determining step for promoting oxygen-evolving activity

“…[28][29][30] Thereupon, it is fundamentally and practically meaningful to understand and tailor the energy barrier of RDS. Recent studies suggest that electronic structure engineering is highly effective for modifying the electronic properties of OER catalysts to afford moderated binding strength between active sites and intermediates, 31,32 thereby leading to a significantly decreased energy barrier of the OER process.…”

The line-scan profile result further showed the hollow heterostructure (Figure 2i).…”

Interfacial built-in electric-field for boosting energy conversion electrocatalysis

“…34 In a binary metal-support catalyst, by tuning the DF between the metal and support, the charge transport orientation across the heterointerface will be greatly affected. 35 As a result, the BIEF will also be greatly tailored, leading to modulation of the hydrogen and hydroxide adsorption. Therefore, focusing on tailoring the DF of the metal or support has been widely accepted in recent years.…”
