Synthesis of green ammonia (NH3 ) via electrolysis nitric oxide (NO) is extraordinarily sustainable, but multielectron/proton-involved hydrogenation steps as well low concentrations NO can lead to poor activities and selectivities electrocatalysts. Herein, it reported that oxygen-defective TiO2 nanoarray supported on Ti plate (TiO2-x /TP) behaves an efficient catalyst for reduction NH3 . In 0.2 m phosphate-buffered electrolyte, such TiO2-x /TP shows competitive electrocatalytic synthesis activity with a maximum yield 1233.2 µg h-1 cm-2 Faradaic efficiency 92.5%. Density functional theory calculations further thermodynamically faster deoxygenation protonation processes (101) compared perfect (101). And the energy barrier 0.7 eV potential-determining step highlights greatly improved intrinsic activity. addition, Zn-NO battery fabricated Zn obtain 241.7 while providing peak power density 0.84 mW

Electrocatalytic reduction of nitrate to NH3 (NO3RR) on Cu offers sustainable production and nitrogen recycling from nitrate-contaminated water. However, affords limited NO3RR activity owing its unfavorable electronic state the slow proton transfer surface, especially in neutral/alkaline media. Furthermore, although a synchronous "NO3RR collection" system has been developed for nitrate-laden water, no is designed natural water that generally contains low-concentration nitrate. Herein, we demonstrate depositing nanoparticles TiO2 support enables formation electron-deficient Cuδ+ species (0 < δ ≤ 2), which are more active than Cu0 NO3RR. TiO2-Cu coupling induces local electric-field enhancement intensifies adsorption/dissociation at interface, accelerating Cu. With dual enhancements, delivers an NH3-N selectivity 90.5%, mass 41.4 mg-N h gCu-1, specific 377.8 h-1 m-2, minimal leaching (<25.4 μg L-1) when treating 22.5 mg L-1 NO3--N -0.40 V, outperforming most reported Cu-based catalysts. A sequential collection based was then proposed, could recycle under wide concentration window 22.5-112.5 rate 209-630 mgN m-2 h-1. We also demonstrated this collect 83.9% (19.3 lake

Mesoporous heterojunction MOF-derived α-Fe2O3/ZnO composites were prepared by a simple calcination of α-Fe2O3/ZIF-8 as sacrificial template. The optical properties confirm that coupling both the modified pore and n-n effectively reduces possibility photoinduced charge carrier recombination under irradiation. mesoporous Fe(25)ZnO with 25% loading α-Fe2O3 exhibited best performance in MB degradation, up to ∼100% after 150 minutes irradiation, higher than pristine ZnO α-Fe2O3. Furthermore, three cycles reusability, still showed an excellent stability 95.42% for degradation MB. proposed photocatalytic mechanism corresponds system.
