Special Issue Information

Dear Colleagues,

The concept of nanocatalysts opens up a new avenue in the field of electrochemistry research and have experienced highly productive decades since the consolidation of this topic. The featuring fine-tuned morphology and microscopic structure were elaborately exploited to access fascinating strain effects, ensemble effects and electronic structure modulations, which demonstrated great potential in diverse electrochemical transformations with distinctive reactivities. Besides, the combined experimental and theoretical studies substantially enriched fundamental understanding of molecular behaviors on surfaces, yielding a framework to understand catalytic trends that can ultimately offer rational guidance toward the development of improved catalysts. To date, the scope of either nanocatalysts or their applications has rapidly expanded, particularly the atomically dispersed catalysts emerge as a recent surge of interest. Moreover, the salient operando techniques and theoretical advances also bring new opportunities to mechanistic insights of complex catalytic network and build on progressive guidelines for catalyst design. Indeed, the thriving nanocatalyst is making its way into unprecedented combinations of rational design and controllable synthesis.

This Special Issue is dedicated to providing a broad survey of the most recent advances in Nanocatalysts for Electrochemical Reactions. Original research articles or reviews that discuss methodologies for synthesis and functionalization of nanocatalysts, structural aspects, catalytic mechanism and properties, and profound perspectives in electrocatalysis fields are welcome.

Abstract
High-efficiency and low-cost multifunctional electrocatalysts for hydrogen evolution reaction (HERs), oxygen evolution reaction (OERs) and oxygen reduction reaction (ORRs) are important for the practical applications of regenerative fuel cells. The activity trends of core–shell Ni6@M32 and Ni6@Pt1M31 (M [...] Read more.
High-efficiency and low-cost multifunctional electrocatalysts for hydrogen evolution reaction (HERs), oxygen evolution reaction (OERs) and oxygen reduction reaction (ORRs) are important for the practical applications of regenerative fuel cells. The activity trends of core–shell Ni6@M32 and Ni6@Pt1M31 (M = Pt, Pd, Cu, Ag, Au) were investigated using the density functional theory (DFT). Rate constant calculations indicated that Ni6@Pt1Ag31 was an efficient HER catalyst. The Volmer–Tafel process was the kinetically favorable reaction pathway for Ni6@Pt1M31. The Volmer–Heyrovsky reaction mechanism was preferred for Ni6@M32. The Pt active site reduced the energy barrier and changed the reaction mechanism. The ORR and OER overpotentials of Ni6@Pt1Ag31 were calculated to be 0.12 and 0.33 V, indicating that Ni6@Pt1Ag31 could be a promising multifunctional electrocatalyst. Ni6@Pt1M31 core–shell clusters present abundant active sites with a moderate adsorption strength for *H, *O, *OH and *OOH. The present study shows that embedding a single Pt atom onto a Ni@M core–shell cluster is a rational strategy for designing an effective multifunctional electrocatalyst. Full article
