Abstract As a green strategy for both ammonia (NH 3 ) production and wastewater purification, electrochemical reduction of nitrate (NO RR) faces challenges due to the nitrite 2 − accumulation competitive hydrogen evolution reaction (HER). Tandem catalysis NO NH offers great potential enhancing selectivity. Herein, iron‐group (Fe, Co, or Ni) nanosheets are introduced onto Cu nanowires construct Cu‐Fe, Cu‐Co, Cu‐Ni tandem systems respectively. Specifically, sites facilitate conversion . Fe sites, similar Cu, reduce , exacerbating rather than converting it their inability precisely capture Co exhibiting excellent moderate HER activity, can seamlessly operate with realize well‐ordered relay catalysis, which achieves superior yield rate 48.44 mg h −1 cm −2 Ni demonstrate removal capability at low overpotentials, leading Faraday efficiency 99.47%. However, its remarkable HER‐active property demonstrated via in situ polarization imaging makes challenge ampere‐level current densities. This work identifies behavior coupled providing reference design further optimization system.

Abstract The development of non‐precious metal‐based electrodes that actively and stably support the oxygen evolution reaction (OER) in water electrolysis systems remains a challenge, especially at low pH levels. recently published study has conclusively shown addition haematite to H 2 SO 4 is highly effective method significantly reducing overpotential extending anode life. far superior result achieved by concentrating centres on oxide particles rather than electrode. However, unsatisfactory Faradaic efficiencies OER hydrogen (HER) parts as well required high load impede applicability upscaling this process. Here it same performance with three times less metal powder if NiO/H suspensions are used along stainless steel anodes. reason for enormous improvement adding NiO electrolyte weakening intramolecular O─H bond molecules, which under direct influence nickel suspended electrolyte. manipulation bonds molecules increase tendency split ground‐breaking development, first example.

Abstract NiFe‐LDH is regarded as one of the most efficient oxygen evolution catalysts, with catalytic activity stems from in‐situ formation NiOOH active phase induced by anodic polarization. In reaction, initially reconstitutes into highly β‐NiOOH phase, which difficult to initiate and stabilize at low potential, will be irreversibly transformed less γ‐NiOOH due over‐oxidation. this work, a novel built‐in electric field (BEF)‐driven surface reconstruction strategy proposed reduce potential required for prevent its This demonstrated in two‐dimensional NiFe‐LDH/Antimonene (2D/2D NiFe‐LDH/AMNSs) heterostructure catalyst, where strong BEF generated through work function engineering. Kelvin probe force microscopy (KPFM) tests, Raman spectra theoretical calculations confirm that enhances electron transfer NiFe‐LDH/AMNSs interface, creating local reduced applied 80 mV NiFe‐LDH. Consequently, record‐low overpotentials 144 209 are achieved 10 300 mA cm −2 reaction (OER), making it best‐performing based catalysts date. It also demonstrates excellent durability hydrogen (HER) activity, ideal overall water splitting.
