Abstract Electrocatalytic nitrate reduction reaction (NO 3 RR) can convert contaminants into ammonia with higher added value. However, due to the NO RR involving complex multi‐electron reactions, there is an urgent need develop efficient electrocatalysts. Herein, CoCu Janus nanoparticles loaded on Ti C 2 T x MXene (CoCu‐Ti ) synthesized via combination of molten salt etching and galvanic replacement strategy. The tandem catalysis NPs maintain balance between nitrogenous intermediates active hydrogen (H ads ). CoCu‐Ti exhibits a high NH yield 8.08 mg h −1 cat. satisfactory Faradaic efficiency 93.6% at −0.7 V versus reversible electrode (RHE). Zn‐NO − battery assembled shows excellent power density 10.33 mW cm −2 , 1.52 95.3% 10 mA which enables simultaneous elimination pollutants, production, energy supply. Moreover, series verification experiments functional theory calculation are combined reveal path catalytic mechanism. This work not only provides new inspiration for design catalysts but also promotes development Zn‐nitrate battery.

This study investigates the utilization of water caltrop pod, an abundant agricultural waste product, as a green extract for optimized biosynthesis copper nanoparticles (CuNPs). To comprehensively characterize pod and biosynthesized CuNPs by sophisticated techniques were employed, including U.V-Vis spectrophotometry probing their preliminary analysis nanoparticles, FT-IR spectroscopy elucidating functional groups present in Scanning Electron Microscopy (SEM) visualizing morphology, Energy Dispersive X-ray (EDX) elemental while Energy-Dispersive (XRD) to determine crystalline structure nanoparticles. Furthermore, antibacterial application these biogenic was explored. The activity (CuNPs) investigated against both Gram-positive (Staphylococcus aureus) Gram-negative (Escherichia coli) bacteria, revealing efficacy combating microbial growth employing Well Diffusion method. Copper showed greater treatment Gram (+ve) bacteria i.e. Staphylococcus aureus compared (-ve) Escherichia coli. research paves way sustainable production bio-functional from biomass, offering promising therapies.
