Hbe theory
WebThe HBE theory aims to consider the interaction between catalysts and H +, simulating a reaction pathway similar to that of HER in acidic media. It was demonstrated by Yan et al. using the cyclic voltammetric curves of polycrystalline Pt as a model catalyst in electrolytes with different pH. [ 31 ] WebFor instance, platinum is known to undergo a decrease from 2 to 3 orders of magnitude of the HER exchange current density from pH = 0 to pH = 13. 32,33 This pH effect thus renders the use of the HBE theory to find a …

WebThis challenges the applicability of HBE theory to describe activity trends for H2 electrocatalysis on TMPs. In this viewpoint, we discuss the structural complexity of TMPs and its impact on the ... WebHydrogen binding energy (HBE) theory is widely recognized for hydrogen electrocatalysis, and the binding strength of the adsorbed hydrogen intermediate (H*) is considered as a suffi-cient descriptor to evaluate catalytic activity in general, following a classical volcano-type relationship.14,15 Due to the

Webcontemporary cultural and ecological contexts. This research will synthesize seven HBE hypotheses in an attempt to understand influences on male parenting strategies among the Na. In turn, I hope to inform HBE theory by specifying how local constraints (e.g., social institutions) affect the general application of HBE hypotheses.
