Transition-metal and nitrogen-codoped carbon-based (TM-N/C) catalysts are promising candidates for catalyzing the oxygen reduction reaction (ORR). However, TM-N/C suffer from insufficient ORR activity, unclear active site structure, poor durability, particularly in acidic solution. Herein, we report single Co atom N codoped carbon nanofibers (Co–N/CNFs) catalyst with high durability desirable activity both alkaline solutions. The half-wave potential of shows a negligible decrease after 10...
Pt atomic clusters (Pt-ACs) display outstanding electrocatalytic performance because of their unique electronic structure with a large number highly exposed surface atoms. However, the small size and specific area intrinsically associated ACs pose challenges in synthesis stabilization Pt-ACs without agglomeration. Herein, we report novel one-step carbon-defect-driven electroless deposition method to produce ultrasmall but well-defined stable supported by defective graphene (Pt-AC/DG)...
High-loaded Pt1Co1-IMC@Pt/C catalyst enables high power PEMFCs, meeting the practical application requirement in electric vehicles.
Ruthenium (Ru) is an ideal substitute to commercial Pt/C for the acidic hydrogen evolution reaction (HER), but it still suffers from undesirable activity due strong adsorption free energy of H* (ΔGH*). Herein, we propose crystalline phase engineering by loading Ru clusters on precisely prepared cubic and hexagonal molybdenum carbide (α-MoC/β-Mo2C) supports modulate interfacial interactions achieve high HER activity. Advanced spectroscopies demonstrate that β-Mo2C shows a lower valence state...
This paper describes a cation exchange approach to the synthesis of metal chalcogenide core-shell particles with same size but number different compositions. method begins preparation colloidal spheres amorphous Se (a-Se), followed by their reaction Ag atoms form Se@Ag2Se spheres. These are then converted into Se@MSe (M = Zn, Cd, and Pb) via Zn2+, Cd2+, Pb2+. All prepared using this monodispersed in characterized spherical shape smooth surface. Starting from batch Se@Ag2Se, resultant samples...
Developing efficient catalysts for steering the electrochemical CO2 reduction reaction (CO2RR) toward high-value chemicals beyond CO and formic acid is highly desirable. Herein, we have developed copper-based confined within a rationally designed covalent triazine framework (CTF-B), featuring CuN2Cl2 structure, selective CO2RR to hydrocarbons with maximum Faradaic efficiency (FE) of 81.3% an FE C2H4 up 30.6%. Operando X-ray adsorption fine structure analyses reveal potential-driven dynamic...
Co/Zn atomic dual-sites anchored on N doped carbon nanofibers for efficient and durable H<sub>2</sub>–O<sub>2</sub> fuel cells (∼0.65 V @ 400 mA cm<sup>−2</sup>, 150 hours).
The conversion of CO2 into valuable chemicals has captured extensive attention for its significance in energy storage and greenhouse gas alleviation, but the development cost-effective electrocatalysts with high activity selectivity remains bottleneck. Herein, we designed a Fe–N–C nanofiber catalyst featuring core–shell structure consisting iron nitride nanoparticles encapsulated within Fe N codoped carbon layers that can efficiently catalyze to CO nearly 100% selectivity, faradic efficiency...
The poor separation and significant recombination of electron–hole pairs slow transfer mobility charge carriers limit the performance BiVO4 for photoelectrochemical (PEC) water splitting. To ameliorate above problems, a novel integrated Ag-embedded MoS2/BiVO4 p–n heterojunction ternary composite electrode is fabricated applied. Surface plasmon resonance (SPR) Ag nanoparticles (NPs) by near-field electromagnetic enhancement or abundant hot electrons injection built-in electrical potential...

Strong transboundary electron transfer in high-entropy quantum-dots significantly accelerates the Tafel kinetics HER, which effectively reduces cost of cathode catalyst proton exchange membrane water electrolysis (PEMWE).
Abstract Atop and multiple adsorbed hydrogen are considered as key intermediates on Pt‐group metal for acidic evolution reaction (HER), yet the role of bridge intermediate ( * H ) is consistently overlooked experimentally. Herein, a Pt atomic chain modified fcc ‐Ru nanocrystal (Pt–Ru( )) developed with co‐crystalline structure, featuring bonded Pt–Ru pair site. Electrons leap from site to facilitate desorption, thus accelerating Tafel kinetics ensuring outstanding electrocatalytic...
A low temperature approach via alcohol reduction has been employed to prepare Au cluster decorated carbon-supported Pt nanoparticles for the oxygen reaction (ORR). X-ray diffraction at wide angles (WAXS) shows that both metallic and exhibit their respective face-centered cubic structures, indicative of no alloy formation between Au. Both WAXS transmission electron microscopy characterizations demonstrate major change in mean particle size bimetallic catalysts was observed even after heat...
