Natural Anthraquinone‐Like Compound Extracted from Green Husk of Walnut Improves Photocatalytic H2O2 Production Catalyzed by TiO2 Nanoparticles

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In this work, a novel biomolecule/semiconductor hybrid catalyst was prepared by loading anthraquinone‐liked juglone onto anatase TiO2. This catalyst exhibited high photocatalytic activity for H2O2 production. Hydrogen peroxide (H2O2) is a vital oxidant with broad industrial applications, and its production via photocatalysis represents a highly ...

A Flexible Poling‐Free Piezoelectric Energy Harvester Based on Gradient Ti‐Doped BiFeO3 Films

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A self‐aligned polarization is realized in compositional gradient Ti‐doped BiFeO3 films via the formation of defect dipoles and strain gradient. The self‐poling behavior is robust to resist high electric field and elevated temperature. The fabricated poling‐free piezoelectric energy harvester delivers output comparable to the poled ones.

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.
