Abstract Developing nonprecious electrocatalysts via a cost‐effective methods to synergistically achieve high active sites exposure and optimized intrinsic activity remains grand challenge. Here low‐cost scaled‐up chemical etching method is developed for transforming nickel foam (NF) into highly electrocatalyst both the hydrogen evolution reaction (HER) oxygen (OER). The synthetic involves Na 2 S‐induced of NF in presence Fe, leading growth ultrathin Fe‐doped Ni 3 S arrays on substrate (Fe x...
Abstract The development of a thin, tunable, and high‐performance flexible electromagnetic (EM) absorbing device that aims to solve signal interference or EM pollution is highly desirable but remains great challenge. Herein, demonstrated electrical‐driven constructed by an insulated organic‐polymer substrate, carrier transmission layer, core–shell structured absorber, enabling narrow tunable effective absorption region ( f E < 2.0 GHz) controlling the external voltage toward this As key...
Abstract The conversion of crystalline metal–organic frameworks (MOFs) into metal compounds/carbon hybrid nanocomposites via pyrolysis provides a promising solution to design electrocatalysts for electrochemical water splitting. However, pyrolyzing MOFs generally involves complex high‐temperature treatment, which can destroy the coordinated surroundings within MOFs, and as result not taking their full advantage electrolysis properties. Herein, simple room‐temperature boronization strategy is...
Sponge‐like composites assembled by cobalt sulfides quantum dots (Co 9 S 8 QD), mesoporous hollow carbon polyhedral (HCP) matrix, and a reduced graphene oxide (rGO) wrapping sheets are synthesized simultaneous thermal reduction, carbonization, sulfidation of zeolitic imidazolate frameworks@GO precursors. Specifically, Co QD with size less than 4 nm homogenously embedded within HCP which is encapsulated in macroporous rGO, thereby leading to the double carbon‐confined hierarchical strong...

Herein, self-template route employed to fabricate unique hybrid composite constructed by encapsulating cobalt nitride (Co5.47N) nanoparticles within three-dimensional (3D) N-doped porous carbon (Co5.47N NP@N-PC) polyhedra, which can be served as active electrocatalyst. To afford...
Abstract Engineering transition metal‐nitrogen‐carbon (TM‐N‐C) catalysts with high‐density accessible active sites and optimized electronic structure holds great promise in the context of electrochemical oxygen reduction reaction (ORR). Herein, a novel modification lysozyme‐modified zeolitic imidazolate framework isolated Co atoms anchored on dominated pyridinic‐N doped carbon (Co‐pyridinic N‐C) is reported. The atomically dispersed allows maximum site exposure while introduction pyridinic N...
Harvesting largely ignored and wasted electromagnetic (EM) energy released by electronic devices converting it into direct current (DC) electricity is an attractive strategy not only to reduce EM pollution but also address the ever-increasing crisis. Here we report synthesis of nanoparticle-templated graphene with monodisperse staggered circular nanopores enabling EM-heat-DC conversion pathway. We experimentally theoretically demonstrate that this nanoporous structure alters graphene's...

The combination theoretical calculations with in/ex situ...
The oxygen reduction reaction (ORR) on a polycrystalline Pt surface was studied using cyclic voltammetry techniques, and the influence of media ORR is examined by comparing in NaOH KOH solutions with concentration ranging from 0.5 to 14 M at 298 K. results show that, solutions, ORR, quasi-reversible diffusion-controlled reaction, largely dependent electrolyte conditions, are superior for process both thermodynamic kinetic consideration. As alkaline increases, performance frustrates,...
Transition metal chalcogenides (TMCs) have been investigated as promising anodes for high-performance lithium-ion batteries, but they usually suffer from poor conductivity and large volume variation, thus leading to unsatisfactory performance. Although nanostructure engineering hybridization with conductive materials proposed address this concern, a better performance toward practical device applications is still highly desired. Herein, we report an iron-doping-induced structural phase...
Abstract Exploring highly active but inexpensive electrocatalysts for the hydrogen evolution reaction (HER) is of critical importance production from electrochemical water splitting. Herein, we report a multicomponent catalyst with exceptional activity and durability HER, in which cobalt nanoparticles were in-situ confined inside bamboo-like carbon nanotubes (CNTs) while ultralow ruthenium loading (~ 2.6 µg per electrode area ~ cm −2 ) uniformly deposited on their exterior walls...

Metal–organic frameworks (MOFs) are periodic organic–inorganic materials that have garnered considerable attention for electrocatalytic applications due to their wide tunability. Metal-hydroxide organic (MHOFs), a subset of MOFs combine layered metal hydroxides with ligands various π–π stacking energy, shown promising catalytic functions, such as the oxygen evolution reaction (OER). The long-term electrochemical stability these OER is unfortunately not well understood, which critical design...
