Doping heteroatoms into metal phosphides to modify their electronic structure is an effective method, but the incomplete exposure of active sites its inherent drawback. In this experiment, both Se doping and P vacancies are simultaneously introduced CoP-Fe2P (named CoFe-P-Se) enhance internal reactivity. Benefiting from unique hollow porous derived MOF-on-MOF template, as well enhanced intrinsic activity achieved by defects doping, CoFe-P-Se exhibits a high specific capacitance 8.41 F cm–2 at current density 2 mA when used supercapacitor electrode. When assembled hybrid with activated carbon, energy reaches 0.488 mWh power 1.534 mW cm–2, capacity retention after 5000 charge–discharge cycles 90.65%. As oxygen evolution reaction (OER) electrode, electrode shows low overpotential only 230 mV 10 278 100 cm–2. Additionally, it excellent stability for over 50 h The designed element vacancy engineering in work will provide insight constructing high-performance electrodes.

Electrocatalysts for oxidation and reduction reactions are crucial sustainable energy production carbon reduction. While precious metal catalysts exhibit superior activity, reducing reliance on them is necessary large‐scale applications. To address this, transition metal‐based studied with strategies to enhance catalytic performance. One promising strategy heterostructures, which integrate multiple materials harness synergistic effects. Developing efficient heterostructured electrocatalysts requires understanding their intricate characteristics, poses challenges. in situ operando spectroscopy provides insights, computational science essential capturing reaction mechanisms, analyzing the origins at atomic scale, efficiently exploring innovative heterostructures. Despite growing recognition of science, standardized criteria these systems remain lacking. This review consolidates case studies propose approaches modeling It categorizes heterostructure types into vertical, semivertical, lateral, defines insights minimizing or exploiting strain effects from lattice mismatches. Furthermore, it summarizes analyses stability activity across reactions, including oxygen evolution, hydrogen reduction, dioxide nitrogen urea oxidation. an overview refine designs establish a framework systematic analysis develop electrocatalysts.

Pursuing cost-effective non-precious metal electrocatalysts is a key challenge in the field of sustainable energy conversion. Transition dichalcogenides, known for their unique electronic structure, demonstrate superior electrocatalytic capabilities hydrogen evolution reaction (HER), yet effectiveness still lacking. In present study, CuS/Co3S4@MWCNT composite was fabricated via single-step hydrothermal synthesis HER applications. This catalyst exploited synergistic effects between CuS and Co3S4 to increase edge site functionalities metallic conductivity, thereby resulting high catalytical activity within material. Furthermore, incorporation multi-walled carbon nanotubes (MWCNTs) into effectively enhanced electron transfer kinetics throughout process. Notably, thiourea serves dual function this synthesis, acting both as reducing agent sulfur source formation sulfides. When evaluated 1 M KOH alkaline electrolyte, synthesized nanocomposite exhibited minimal overpotential 300 mV reach current density 10 mA/cm2, Tafel slope merely 76.2 mV/dec, indicative its good catalytic activity. These findings underscore composite’s potential application production technologies.
