Abstract Tailoring the morphology and crystal structure of metallene is critical to improve its electrocatalytic performance. In this work, hetero‐phase RhB ( h ‐RhB metallene) with amorphous/crystalline readily prepared by a two‐step method. The very unique in non‐metallic heteroatom doping structure. Benefiting from optimized electronic states induced incorporation B atoms, exhibits superior performance for hydrogen evolution reaction peroxide electro‐oxidation (HPOR). When coupled HPOR, metallene|| water electrolysis two‐electrode system lower cell voltage 0.379 V (@ 10 mA cm −2 ) compared overall splitting (1.35 V). presented synthetic method provides powerful strategy design energy‐saving H 2 production.

Electrocatalytic CO 2 reduction reaction (CO RR) to produce formate (HCOOH) attracts special interest in the upgrade of waste . For selective conversion into HCOOH, preferable binding *OCHO compared with *COOH is a prerequisite, which presents great challenge rational design catalytic active center. Recently, alkaline‐earth (AE) metals as centers have been reported for electrocatalysis. Herein, feasibility AE heterogeneous catalysis electrocatalytic RR toward HCOOH based on series metal single‐atom catalysts (SACs) theoretically studied. High‐throughput first‐principles calculations reveal that, all studied systems, preferably adsorb *OCHO, enabling exclusive production. Especially, Mg SACs embedded graphene and Ca SAC anchored g‐C N can efficiently convert under near‐zero potential, both systems exhibit high stability. Mechanistic investigation indicates that are highly ionic, strongly bind mainly through electrostatic attraction interaction. This study lays theoretical foundation efficient electroreduction selectivity, further emphasizes potential catalysis.

With the rapid development of economy, increasing energy crisis and environmental pollution urge us to develop sustainable clean novel systems. Among them, electrochemical conversion technology is considered as one ideal potential alternative systems, electrocatalysts play critical roles but are still challenging. Metal-organic frameworks (MOFs), thanks their regular channels, atomically dispersed active centers, adjustable chemical pore environments, have severed promising for conversion. However, relatively low conductivities instabilities MOFs limit wide application in this field. In case, fabricating hybrids carbon-based materials an effective way overcome above deficiencies. addition, synergistic effects between carbons could optimize electronic structures sites promote surface areas, thus improve electrocatalytic performances composites. Herein, we outline current MOF/carbon composites, including fabrication methods hybridized with various dimensions electrocatalysis utilization water splitting, hydrogen evolution reaction (HER), oxygen (OER), reduction (ORR). Finally, advantages challenges such catalysts highlighted future endeavors on composites HER, OER ORR discussed.
