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 ...

Dual‐Enhancement Strategy for OER via Ni–Co–Fe Tri‐Level Electron Regulation and La‐Assisted Structural Stabilization: LaFe Selective Coating on CoCH/NF Precatalyst

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A synergistic dual‐modulation strategy integrates Ni activation via stepwise electronic regulation and La‐induced stabilization during electrochemical reconstruction. The hierarchical LaFe–CoCH/NF precursor transforms into a robust La/NiCoFeOOH interface, delivering optimized electronic structure, high turnover frequency (TOF400 = 1.23 s⁻¹), and ...

Nonequilibrium Laser Regulation of the Electronic Structure of the Ni‐Based Electrode for Boosting Nucleophilic Electrooxidation of Alcohols

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reports an efficient, simple, low‐cost, and scalable method for overall electrode preparation. Nonequilibrium laser synthesis rapidly yields NiO nanocrystals on which a nickel oxyhydroxide (NiOOH) overlayer is grown in situ. By varying the number of laser pulses, the Ni3+/Ni2+ ratio is precisely tuned, thereby modulating the electronic ...
