Arsenic sorption on zero-valent iron-biochar complexes

Water Research, 2018
Arsenic (As) is toxic to human and is often found in drinking water in India and Bangladesh, due to the natural abundance of arsenides ores. Different removal procedures such as precipitation, sorption, ion exchange and membrane separation have been employed for removal of As from contaminated drinking water (CDW), however, there is a critical need for

Cu‐Doped Amorphous High‐Entropy Hydroxides Activating Electrochemical Reconstruction: Triggering LOM and Chloride Repellency for Enhanced Water and Seawater Oxidation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Copper‐doped amorphous high‐entropy hydroxide (CuNiCoFeCrOH) is constructed via one‐step electrodeposition. Cu doping promotes electrochemical reconstruction by accelerating Cr leaching and re‐adsorption, triggering LOM and chloride repellency for efficient water and seawater oxidation.

Enhanced Electron‐Capturing by Single‐Atomic Iron on Pyridinic N‐Deficient Carbon Drives Self‐Oxidative Degradation of Pollutants

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Pyrolysis of FeOx/g‐C3N4 and ZIF‐8 is performed to introduce Fe single atom and pyridinic nitrogen vacancies onto N‐doped carbon. This modification enables the materials to efficiently extract electrons from ciprofloxacin (CIP) and activate dissolved oxygen. 100% of CIP was degraded within 1 min without adding any oxidant.

Enhanced Structural Reversibility and Electrochemical Stability Via Fe3+/Fe4+ Stabilization in a P3‐Type Layered Na0.7[Mn0.5Fe0.4Li0.1]O2 Cathode at High‐Voltages

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Partial Li substitution for Fe in a P3‐Type layered Na0.7[Mn0.5Fe0.4Li0.1]O2 cathode stabilizes the iron redox behavior, particularly at higher charging voltage up to 4.5 V (vs Na/Na+), that enables more reversible sodium‐ion storage capacity and significantly improves capacity retention.
