Abstract The production of hydrogen peroxide (H 2 O ) through two‐electron oxygen reduction reaction (2e − ORR) has emerged as a more environmentally friendly alternative to the traditional anthraquinone method. Although oxidized carbon catalysts have intensive developed due their high selectivity and activity, yield conversion rate H under overpotential still limited. produced was rapidly consumed by increased intensity reduction, which could ascribe decomposition radicals voltage in catalyst. To overcome this issue, B doped been catalyze 2e ORR with efficient suppressing at potential. Thus, thermal reducing containing groups (OCGs) on graphite construct defects vacancies, situ convert B−C x subunits edge graphene sheets. introduction effectively prevented *O−O bond provided suitable adsorption capacity for *OOH, achieving excellent across wide range. Finally, remarkable 7.91 mmol cm −2 h −1 delivered an industrial current density 600 mA , provide “green” pathway scale‐upable synthesis .

Methyl orange (MO) is an organic synthetic dye widely used in laboratory and industrial applications. In settings, it serves as acid-base indicator due to its distinct color change both acidic alkaline environments. Industrially, primarily utilized the textile industry for ultraviolet (UV) absorption properties. However, discharge leakage of methyl into environment can cause severe ecological damage pose potential carcinogenic teratogenic risks human health. Therefore, detecting quantifying concentration various matrices crucial. This study reports synthesis graphene quantum dots (GQDs) from peel a precursor, using ethanol dimethylformamide (DMF) solvents. Cyan (c-GQDs) yellow (y-GQDs) were synthesized through bottom-up hydrothermal method. The difference attributed redshift caused by varying ratio pyridine nitrogen pyrrole nitrogen. These GQDs exhibited notable optical properties, with c-GQDs emitting cyan fluorescence y-GQDs under UV light. To investigate quenching effects, nine commonly dyes tested, all found quench y-GQDs, having most significant effect. peel-derived presence poor dispersion DMF solution. Additionally, possess high specific surface area, abundant functional groups, excellent electronic conductivity, which contribute their effective performance. average thickness (the vertical dimension substrate upwards) was 3.51 nm, confirming graphene-like structure. They emitted within wavelength range 450-530 nm. Notably, linear correlation between intensity (regression coefficient = 0.9954), indicating sensing materials pollutant detection.

Abstract Electrochemical nitrate (NO 3 − ) reduction to ammonia (NH presents a promising route for both wastewater treatment and generation but still suffers from sluggish catalytic activity, insufficient mass transfer, the reliance on high‐concentration supporting electrolytes. This work reports an innovative efficient electrosynthesis reactor by integrating self‐assembled iron‐doped Ni 2 P (Fe‐Ni P/NF) nanoflower cathode with solid‐electrolyte (SE). The SE design eliminates need electrolytes, providing highly ion‐conducting pathway enabling direct production of NH NO . Through tailoring electronic surface characteristics Fe‐Ni P/NF, this achieves complete reduction, 96.7% selectivity, 81.8% faradaic efficiency concentration 100 m at current density mA −2 Density functional theory (DFT) calculations reveal that phosphating Fe doping synergistically enhance adsorption increase availability active hydrogen, thus favoring low energy barrier 0.695 eV. Additionally, superhydrophilicity P/NF catalyst promotes transfer facilitating electrolyte access ensuring rapid gas bubble release. study provides sustainable scalable method converting ‐laden into valuable products.
