ConspectusDiamond composite (DC) refers to a system which consists of diamond (Dia) and other components. Various interactions between components exist. The first DC, Dia/β-silicon carbide (β-SiC) composite, was grown in 1992 by means chemical vapor deposition (CVD) technique. Later on, precise control the distribution, crystallinity, orientation both β-SiC phases these composites sequentially achieved, generating numerous Dia/β-SiC further leading their wide applications diverse fields. Inspired activities composites, DCs, produced using different CVD techniques, have been reported, including Dia/carbides, Dia/oxides, Dia/nitrides, Dia/sp2-carbon, Dia/metal, Dia/metal alloy, Dia/organic composites. Meanwhile, possess micro- nanostructures. Since DCs fully combine outstanding properties with those components, utilization mechanical, physical, chemical, biomedical fields extensively explored tested. This "1 + 1 > 2" strategy is believed be extremely efficient useful design explore advanced functional materials. origin superior enhancement and/or new stems from interface individual as well synergistic effects.This Account summarizes progress achievements our group. Their typical synthesis methods, namely, dry wet ones, are overviewed. methods conducted gas phase(s), covering high-pressure high-temperature (HPHT) method, physical (PVD). While mainly include electrochemical hydrothermal processes. features then detailed. Some application examples highlighted. In second part this Account, especially photo/electrochemical features, illustrated, for example, electrocatalysis Dia/graphite toward oxygen reduction/evolution reactions (ORR/OER) construction flexible zinc-air batteries, use Dia/oxides (carbide) battery-like supercapacitors, employment Dia/TiO2 photoelectrochemical degradation environmental pollutants, sensing. finishes future prospects encompassing meticulous conceptualization synthesis, multifarious across domains.

Abstract The development of high‐performance bifunctional electrocatalysts for the oxygen evolution reaction (OER) and hydrogen (HER) is crucial efficient cost‐effective water splitting in sustainable production. A significant challenge this area engineering active sites that maintain robust stability high activity under varying electrochemical conditions encountered both alkaline acidic media. This study presents Co 80 Ru 1 ‐NCNFs, an advanced electrocatalyst showcases a self‐supported carbon nanofiber membrane with uniformly dispersed Ru‐modified Co‐N 4 sites, excelling OER HER. trace incorporation (0.09 wt%) significantly enhances catalytic through synergistic Co/Ru interactions. ‐NCNFs demonstrate promising performance 1.0 m KOH, along remarkable HER conditions. Density functional theory (DFT) calculations reveal optimizes adsorption energies intermediates on thereby improving kinetics. work provides critical insights design stable energy conversion.

With unique 4f electronic shells, rare earth metal-based catalysts have been attracting tremendous attention in electrocatalysis, including oxygen reduction reaction (ORR). In particular, atomically dispersed Ce/CeO2-based explored extensively due to several features. This review article provides a comprehensive understanding of (i) the significance effect Ce high-spin state on ORR activity enhancement Pt and non-pt electrocatalysts, (ii) spatially confining stabilizing ceria generation transition catalysts, (iii) experimental theoretical evidence Ce3+ ↔ Ce4+ redox pain radical scavenging, (iv) electrons d-band center electron transfer between N-doped carbon metal for enhanced activity, (v) Pt/CeO2/carbon heterojunctions stability electrocatalyst ORR. Among strategies synthesizing Ce/CeO2 metal–organic framework (MOF)-derived are being perused tendency readily coordinate with O- N-containing ligands, which upon undergoing pyrolysis, results formation high surface area, porous networks metallic/clusters/nanoparticles active sites. paper an overview recent advancements regarding derived from MOF precursor fuel cells metal–air battery applications we conclude insights into key issues future development directions.
