Electrochemical Degradation of Plastic Waste Coupled with Hydrogen Evolution in Seawater Using Rosette‐Like High‐Entropy Oxides

Advanced Science, EarlyView.
Rosette‐like high‐entropy NiCoFeMnAlOx enable the electrochemical degradation of PGA plastic waste in seawater, coupling glycolic acid oxidation with hydrogen evolution. Abundant OH* species lower energy barriers for C─C and C─H bond activation, while in situ and theoretical studies reveal the catalytic mechanism.

Innovative Design of PEI‐Modified AMO‐Layered Double Hydroxide for Efficient and Stable Direct Air Capture of CO2

Advanced Science, EarlyView.
An uncalcined, hydroxyl‐rich MgAl layered double hydroxide, synthesized via low‐energy aqueous miscible organic solvent treatment, enables mesopore‐engineered polyethyleneimine anchoring for direct air capture (DAC). The exfoliated structure exposes abundant hydroxyls that stabilize amines via hydrogen bonding, effectively suppressing oxidative ...

Moisture Harvesting by the Structure Regulation of Hygroscopic Hydrogel for Energy and Water Sustainability

Advanced Electronic Materials, EarlyView.
Hygroscopic hydrogels are capable of utilizing the moisture from air, which can transfer the gaseous water to liquid by a surface phase transition. Taking advantage of this water, sustainable water production, thermal management, and electricity generation can be realized.

Ru Single Atoms Anchored on Co3O4 Nanorods for Efficient Overall Water Splitting under pH‐Universal Conditions

Advanced Energy Materials, EarlyView.
A Ru8%‐Co3O4 catalyst containing Ru single atoms (SAs) exhibits exceptional oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) performance in acidic, neutral, and alkaline media. When used as the anode and cathode catalysts in an anion exchange membrane water electrolyzer (AEMWE) device, a low cell voltage of just 2.06 V is needed to
