Abstract Proton exchange membrane water electrolysis (PEMWE) is a key technology to solve the serious energy and environmental problems. However, poor durability of electrocatalysts in acidic oxygen evolution reaction (OER) environment hinders large‐scale application PEMWE. Herein, robust RuMn electrochemical catalyst with remarkable within 20 000 cyclic voltammetry cycles reported. Furthermore, stable for 720 h at 10 mA cm –2 current density 0.5 M H 2 SO 4 solution <100 mV overpotential...
Ammonia is of great importance in fertilizer production and chemical synthesis. It can also potentially serve as a carbon-free energy carrier for future hydrogen economy. Motivated by worldwide effort to lower carbon emissions, ammonia synthesis lithium-mediated electrochemical nitrogen reduction (LiNR) has been considered promising alternative the Haber-Bosch process. A significant performance improvement LiNR achieved recent years exploration favorable lithium salt proton donor electrolyte...
A feasible membrane electrode assembly (MEA) configuration is proposed for lithium-mediated electrochemical nitrogen reduction to ammonia, which shows the advantages of efficient gas transfer, reduced solvent consumption and compact configuration.
Rationally combining designed supports and metal-based nanomaterials is effective to synergize their respective physicochemical electrochemical properties for developing highly active stable/durable electrocatalysts. Accordingly, in this work, sub-5 nm monodispersed nanodots (NDs) with the special nanostructure of an ultrafine Cu1Au1 core a 2-3-atomic-layer Cu1Pd3 shell are synthesized by facile solvothermal method, which further evenly firmly anchored onto 3D porous N-doped graphene...
Green synthesis of ammonia by electrochemical nitrogen reduction reaction (NRR) shows great potential as an alternative to the Haber-Bosch process but is hampered sluggish production rate and low Faradaic efficiency. Recently, lithium-mediated NRR has received renewed attention due its reproducibility. However, further improvement system restricted limited recognition mechanism. Herein, we demonstrate that began with deposition lithium, followed two chemical processes dinitrogen splitting...
Ammonia synthesis by electrochemical nitrogen reduction reaction (NRR) is a promising alternative to the Haber–Bosch process. Accurate measurement of produced ammonia requires rigorous criteria, which rely on deeper understanding characteristics. Herein, we systematically investigated interaction with Nafion membrane and electrolyte reveal factors that may induce deviation in measurements. We demonstrated desirable characteristics as separator view low adsorption rate diffusion for ammonia....
Electrochemical nitrogen reduction reaction (NRR) is intensively investigated by researchers for its potential to be the next-generation technology produce ammonia. Many attempts have been made explore possibility of electrochemical ammonia production catalyzed noble metals. However, produced in most reported cases ppm level or even lower, which susceptible contaminants experiments, leading fluctuating contradictory results. Herein, a rigorous procedure was adopted systematically evaluated...
Gold nanoclusters (AuNCs) are emerging as promising functional probes for bioapplications. However, because of rapid renal clearance, it is a challenge to tailor their biofate and improve disease-targeting ability in vivo. Herein, we report an efficient strategy organotropic actions by rationally designing AuNC assemblies. The nanocluster assembly established based on the moderate electrostatic interaction or strong coordination between AuNCs, enabled solely chitosan (CS) coadded chelating...
Developing efficient oxygen reduction reaction (ORR) electrocatalysts is critical to fuel cells and metal-oxygen batteries, but also greatly hindered by the limited Pt resources long-standing linear scaling relationship (LSR). In this study, ∼6 nm highly uniform Pd nanospheres (NSs) having surface-doped (SD) P-O species are synthesized evenly anchored onto carbon blacks, which further simply heat-treated (HT). Under alkaline conditions, Pd/SDP-O NSs/C-HT exhibits respective 8.7 (4.3)- 5.0...
