Key Points

The study aims to explore the role of lattice hydrogen as an active mediator in electrocatalysis, challenging traditional models.
Utilized a surface-centric model to assess hydrogen's role in electrocatalysis
Compared lattice hydrogen interactions against transient adsorbate concepts
Analyzed the implications of findings on established electrocatalysis principles
Lattice hydrogen is identified as a significant factor in improving reaction efficiency.
Challenged existing notions of hydrogen's role based on the Sabatier principle.
Proposed new approaches for optimizing electrocatalytic processes.

Implication

Examines the role of lattice hydrogen in electrocatalysis, suggesting new paradigms for hydrogen interactions.

Abstract

Traditionally, electrocatalysis has been conceptualized through a surface-centric model, wherein hydrogen is seen just as a transient adsorbate adhering to the Sabatier principle. Lattice hydrogen fundamentally challenges the surface-centric paradigm...
