Electrocatalytic water splitting is pivotal for advancing the hydrogen economy, yet conventional stable-phase catalysts are constrained by rigid crystal structures and electronic states, leading to fixed active sites, limited adaptability, sluggish kinetics. Metastable materials emerge as promising alternatives due their structural flexibility tunable properties; however, dynamic regulatory mechanisms remain underexplored. This review uniquely offers a comprehensive analysis of metastable catalysts, emphasizing how factors such size, phase structure, properties, defects, interfaces significantly enhance catalytic performance. By dissecting range (metals, alloys, oxides, sulfides, nitrides, hydroxides), we elucidate precise modulation strategies that improve efficiency stability. Practical applications highlight superior adaptability activity compared traditional catalysts. Addressing key challenges technical bottlenecks, this provides innovative insights strategic directions optimizing materials, thereby efficient sustainable energy conversion technologies.

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.
