Great enthusiasm in single-atom catalysts (SACs) for the oxygen reduction reaction (ORR) has been aroused by discovery of M-NX as a promising ORR catalysis center. However, performance SACs lags far behind that state-of-the-art Pt due to unsatisfactory adsorption-desorption behaviors reported catalytic centers. To address this issue, rational manipulation active site configuration toward well-managed energy level and geometric structure is urgently desired, yet still remains challenge....
Emerging as a new frontier in heterogeneous catalysis, single-atom site catalysts (SSCs) have sparked enormous attention and bring about opportunities to oxygen reduction electrocatalysis. Despite considerable progress achieved recently, most of the reported SSCs suffer from either insufficient activity or unsatisfactory stability, which severely retards their practical application. Here, we demonstrate novel Ru-SSC with appropriate adsorption free energy OH* (ΔGOH*) confer excellent low...
Single-atom catalysts (SACs) are attracting widespread interest for the catalytic oxygen reduction reaction (ORR), with Fe-Nx SACs exhibiting most promising activity. However, Fe-based suffer serious stability issues as a result of oxidative corrosion through Fenton reaction. Herein, using metal-organic framework an anchoring matrix, we first time obtained pyrolyzed Cr/N/C ORR, where atomically dispersed Cr is confirmed to have Cr-N4 coordination structure. The catalyst exhibits excellent...
Water electrolysis is an emerging energy conversion technology, which significant for efficient hydrogen (H2) production. Based on the high-activity transition metal ions and alloys of ultrastable bifunctional catalyst, evolution reaction (HER) oxygen (OER) are key to achieving method by overall water splitting (OWS). This study reports that Co-based coordination polymer (ZIF-67) anchoring indium-organic framework (InOF-1) composite (InOF-1@ZIF-67) treated followed carbonization...
Vehicular ad hoc networks (VANETs) can significantly improve traffic safety and efficiency. The basic idea is to allow vehicles send information roadside units (RSUs) or other vehicles. Vehicles have be prevented from some attacks on their privacy misuse of private data. For this reason, security preservation issues are important prerequisites for VANETs. identity-based batch verification (IBV) scheme has been recently proposed make VANETs more secure efficient practical use. In paper, we...
Single Ru atoms are uniquely located on the top of trivalence Fe atom NiFe layered double hydroxide.
Catalyst/support interaction plays a vital role in catalysis towards acidic oxygen evolution (OER), and the performance reinforcement is currently interpreted by either strain or electron donation effect. We herein report that these views are insufficient, where dynamic of interface under potential bias must be considered. Taking Nb2 O5-x supported iridium (Ir/Nb2 ) as model catalyst, we uncovered migration species between IrOx during OER. Direct spectroscopic evidence combined with...
Proton-exchange membrane fuel cells (PEMFCs) are limited by their extreme sensitivity to trace-level CO impurities, thus setting a strict requirement for H2 purity and excluding the possibility directly use cheap crude hydrogen as fuel. Herein, we report proof-of-concept study, in which novel catalyst comprising both Ir particles single-atom sites (IrNP @IrSA -N-C) addresses poisoning issue. The found not only be good oxidizing sites, but also excel scavenging molecules adsorbed on close...
Hollow carbon materials are regarded as crucial support in catalysis and electrochemical energy storage on account of their unique porous structure electrical properties. Herein, an indium-based organic framework InOF-1 can be thermally carbonized under inert argon to form indium particles through the redox reaction between nanosized oxide matrix. In particular, a type hollow nanostraw (HCNS) is situ obtained by combining fusion removal within decarboxylation process. The as-synthesized...
The acidic water-splitting technology based on the polymer exchange membrane can produce hydrogen efficiently, continuously, and cleanly, which is expected to alleviate energy crisis. However, even noble metal-based electrocatalysts such as IrOx species would dissolve rapidly during oxygen evolution. Herein, we successfully assemble high-density carbon nanotubes (CNTs) encapsulated with IrCo nanoparticles (NPs) cloth (IrCo@CNT/CC) using a facile MOF-templated dicyandiamide-assisted pyrolysis...
A broadband metamaterial absorber (MA) based on lumped elements is presented, which composed of the dielectric substrate sandwiched with metal split-coin resonators (SCR) welded and continuous film. We simulated, fabricated, measured MA. Compared single SCR structure MA, composite MA loaded has a wider absorptivity works in lower frequency. The experiment results show that bandwidth absorption 90% about 1.5 GHz full width at half maximum (FWHM) can be up to 50%, also nearly unchanged for...
