Microwave Shock Synthesis of Porous 2D Non‐Layered Transition Metal Carbides for Efficient Hydrogen Evolution

SusMat, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 24, 2024

ABSTRACT Transition metal carbides (TMCs) serve as efficient catalysts for electrocatalytic hydrogen evolution reactions (HERs), holding significant importance in promoting production carbon neutrality. To optimize interfacial catalytic activity, structurally designing TMCs into two‐dimensional (2D) and porous structures to expose more practical surface areas enhance electronic configurations is a common effective strategy. Particularly, 2D non‐layered (2D NL‐TMCs) demonstrate richer active sites distinct from layered inertness. However, mainstream selective etching chemical deposition growth mechanisms struggle prepare highly NL‐TMCs due constraints posed by their high structural strength formation temperature. Herein, we successfully synthesized W 2 C p‐W C) rapidly using microwave shock method. Mechanistic verification reveals that leveraging transient temperature rapid on‐off properties of effectively combines with an oxidation‐induced porosity mechanism, facilitating the structures. These low‐dimensional nanostructures abundant edge defect aid adsorption intermediate species HER. Moreover, successful preparation series (Mo C, NbC, TaC) confirms universality this method, exhibiting optimal HER performance. This strategy offers new insights topological synthesis NL crystals.
