Unveiling the Potential of Metal and Non‐Metal Modified Porous Carbon for the Electrochemical Reduction of CO2

Carbon Energy, EarlyView.
Earth‐abundant metal‐ and non‐metal‐modified porous carbons offer a highly tunable platform for electrochemical CO2 reduction. This review shows how electronic interactions, active‐site coordination, pore architecture, and cooperative catalytic effects jointly govern intermediate stabilization, product selectivity, and device‐relevant CO2RR performance.

Enhanced nitrate reduction by HPMC-stabilized nanoscale zero-valent iron (H-NZVI): Synthesis, characterization and reaction kinetics

Desalination and Water Treatment
Nano zero-valent iron (NZVI) was successfully stabilized by using hydroxypropyl methyl cellulose (HPMC). Systematic characterization observations (including XRD, TEM, FTIR, and VSM), as well as settling performance, illustrated that, compared to bare ...

Reduction of Hexavalent Chromium by Nano Zero-Valent Iron

Quality of Life (Banja Luka) - APEIRON
Hexavalent chromium is a toxic form of chromium that has significant health and environmental implications. Reducing hexavalent chromium to trivalent chromium is a crucial step in immobilizing and removing Cr(VI) from water resources. Nano zero-valent iron (nZVI) as an electron-donating agent was used for Cr(VI) reduction in aqueous solution.
