Abstract Developing non‐precious‐metal electrocatalysts that can operate with a low overpotential at high current density for industrial application is challenging. Heterogeneous bimetallic phosphides have attracted much interest. Despite hydrogen evolution reaction (HER) performance, the ordinary oxygen (OER) performance hinders their practical use. Herein, it shown Fe‐doping reverses and enlarges interfacial electrical field heterojunction, turning H intermediate favorable binding sites HER into O OER. Specifically, self‐supported heterojunction catalysts on nickel foam (CoP@Ni 2 P/NF Fe‐CoP@Fe‐Ni P/NF) are readily synthesized. They only require overpotentials of 266 274 mV to drive large 1000 mA cm −2 ( j ) OER, respectively. Furthermore, water splitting cell equipped these electrodes requires voltage 1.724 V excellent durability, demonstrating potential application. This work offers new insights engineering catalysts.

Electrochemical reformation of nitrate wastewater and poly(ethylene terephthalate) (PET) plastic waste into ammonia (NH3) fine chemicals is a sustainable strategy for resource utilization. Herein, co-production system glycolic acid (GA, degradable polymer monomer) constructed by coupling reduction ethylene glycol (EG, in PET hydrolysate) oxidation. Low-crystalline CoOOH (LC-CoOOH/CF) Pd nanothorns (Pd NTs/NF) grown situ on the metal foam substrates are employed as cathode anode, respectively. The high density amorphous regions LC-CoOOH/CF enables enhanced adsorption provides abundant active sites, ultimately leading to an Faradic efficiency (FE) 97.38 ± 1.0% at −0.25 V vs reversible hydrogen electrode (RHE). Meanwhile, unique nanothorn morphology endows NTs/NF with high-curvature tip, triggering tip effect (TE) promote highly selective oxidation EG GA. Furthermore, two-electrode system, NH3 GA operated low energy consumption (onset voltage: 0.5 V), much lower than traditional electrolysis process (1.4 V). This study method utilization co-produce value-added chemicals.

Metal-oxygen bonds significantly affect the oxygen reaction kinetics of metal oxide-based catalysts but still face bottlenecks limited cognition and insufficient regulation. Herein, we develop a unique strategy to accurately tailor metal-oxygen bond structure via amorphous/crystalline heterojunction realized by ion-exchange. Compared with pristine amorphous CoSnO3-y, iron ion-exchange induced strengthens Sn-O bond, weakens Co-O strength, introduces additional Fe-O accompanied abundant cobalt defects optimal larger pore specific surface area. The optimization is dominated introduction crystal further promoted rich Co defect. Remarkably, Fe doped catalyst (Co1-xSnO3-y-Fe0.021-A/C) demonstrates excellent evolution reduction activities smaller potential gap (ΔE = 0.687 V), Zn-air battery based Co1-xSnO3-y-Fe0.021-A/C exhibits output power density, cycle performance, flexibility.
