Abstract Single‐atom Fe‐N‐C (denoted as Fe 1 ‐N‐C) catalysts exhibit inadequate bifunctional activities to conquer the sluggish oxygen reduction and evolution reaction (ORR/OER), hindering their practical applications in rechargeable Zn‐air batteries (ZABs). Here, by employing ‐N‐C hollow nanorods ORR‐active support, OER‐active NiFe‐layered double hydroxide (NiFe‐LDH) nanodots are evenly decorated through a spatially confined process form NiFe‐LDH/Fe heterostructure with abundant accessible...
Electrocatalytic CO2 reduction reaction (CRR) is one of the most promising strategies to convert greenhouse gases energy sources. Herein, CRR was applied towards making C1 products (CO, HCOOH, CH3 OH, and CH4 ) on g-C3 N4 frameworks with single Ni, Co, Fe introduction; this process investigated by density functional theory. The structures electrocatalysts, adsorption configurations, mechanisms were systematically studied. Results showed that located from corner cavity center. Analyses...
Transition metal-nitrogen-carbon materials (M-N-Cs), particularly Fe-N-Cs, have been found to be electroactive for accelerating oxygen reduction reaction (ORR) kinetics. Although substantial efforts devoted design Fe-N-Cs with increased active species content, surface area, and electronic conductivity, their performance is still far from satisfactory. Hitherto, there limited research about regulation on the spin states of Fe centers electrocatalysts improve catalytic performance. Here, we...
Abstract Lithium metal is the ultimate anode material for pursuing increased energy density of rechargeable batteries. However, fatal dendrites growth and huge volume change seriously hinder practical application lithium batteries (LMBs). In this work, a host that preinstalled CoSe nanoparticles on vertical carbon vascular tissues (VCVT/CoSe) designed fabricated to resolve these issues, which provides sufficient Li plating space with robust framework, enabling dendrite‐free deposition. Their...
Strong metal‐support interaction (SMSI) can be normally induced by the surface free energy differences between metal nanoparticles and supports. To gain deeper insights into effect of SMSI on heterogeneous catalysis, we use prototype Pt, Pd/TiO2(anatase) systems to demonstrate different reverse water gas shift (RWGS) reaction activity changes, especially with increasing nanoparticle (NP) loading. Our experiments show that conventional surface‐free‐energy change law regarding incremental NP...

Abstract The low energy efficiency and limited cycling life of rechargeable Zn–air batteries (ZABs) arising from the sluggish oxygen reduction/evolution reactions (ORR/OERs) severely hinder their commercial deployment. Herein, a zeolitic imidazolate framework (ZIF)‐derived strategy associated with subsequent thermal fixing treatment is proposed to fabricate dual‐atom CoFe─N─C nanorods (Co 1 Fe ─N─C NRs) containing atomically dispersed bimetallic Co/Fe sites, which can promote cyclability...
A highly efficient and pH-universal hydrogen evolution reaction (HER) electrocatalyst with a sandwich-architecture constructed using zero-dimensional N- P-dual-doped core-shell Co2 P@C nanoparticles embedded into 3 D porous carbon sandwich (Co2 P@N,P-C/CG) was synthesized through facile two-step hydrothermal carbonization pyrolysis method. The interfacial electron transfer rate the number of active sites increased owing to synergistic effect between N,P-dual-doped sandwich-nanostructured...
Transition metals (TMs) have been widely employed to realize various electrocatalytic applications of pristine materials. Herein, via density functional theory (DFT), the potential for hydrogen evolution reaction (HER) all single TMs embedded in Ti2N was screened. Our results show that can tune adsorption with a volcano-like tendency, and Mo-Ti2N stands out an optimal Gibbs free energy (ΔGH) −0.097 eV. This be further improved ΔGH close thermal neutrality by applying 1.2% tensile strain...
Abstract Although metal‐organic frameworks (MOFs) show promise as electrocatalysts due to their unique intrinsic features, activity and stability often fall short. Herein, NiFe‐MOFs is used a model introduce group VIB metalates (Na 2 WO 4 , Na CrO MoO ) into the topological conversion process of layer double hydroxide (LDHs)/MOFs, creating series interstitial element‐doped LDHs/MOFs catalysts. The engage in alkaline hydrolysis MOF, generating LDHs on MOF surface. Furthermore, altering pH...
Abstract Sodium‐based rechargeable batteries are some of the most promising candidates for electric energy storage with abundant sodium reserves, particularly, sodium‐based dual‐ion (SDIBs) perform advantages in high work voltage (≈5.0 V), high‐power density, and potentially low cost. However, irreversible electrolyte decomposition co‐intercalation solvent molecules at electrode interface under a charge state blocking their development. Herein, high‐salt concentration microenvironment is...
