Polycarbazole–NiOOH Interfacial Engineering of BiVO4 Photoanodes for Efficient and Stable Solar Water Splitting

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A π‐conjugated carbazole (p‐CBZ) layer is electro‐polymerized on BiVO4 to form a p–n heterojunction that enhances charge separation and suppresses surface recombination, while a NiOOH co‐catalyst accelerates oxygen evolution kinetics. The synergistic BVO/p‐CBZ/NiOOH photoanode delivers a high photocurrent density and long‐term stability for efficient ...

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

open access: yesENERGY &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 ...

State‐Level Politics in Forest Governance: The Role of the Narrative‐Policy Nexus in the Brazilian Amazon

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Deforestation and its social impacts are an enduring challenge in agrarian frontiers, especially in the tropics. Fueled by global demand for commodities, this process is mediated by ideas, concepts, meanings, and policies that uphold socioenvironmental degradation. A key and understudied—arena in which this mediation occurs is the sub‐national

Ground‐ and Excited‐State Mixed Valency in a 4,4′‐Bipyridine‐Bridged Bimetallic Di‐Ruthenium Complex

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Photoinduced mixed‐valence interactions across a 4,4′‐bpy bridge were studied. MLCT excited states in the bimetallic complex are longer‐lived than in the monometallic reference, thanks to metal–metal electronic coupling and hole delocalization, but are still shorter than the nanosecond timescale relevant for diffusional reactivity.

Biomass‐derived hydrochars as eco‐friendly adsorbents for wastewater treatment applications

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract Emerging organic pollutants (EOPs), such as diethyl phthalate (DEP), bisphenol A (BPA), and methylene blue (MB), are only partially removed in conventional wastewater treatment plants. This study assesses hydrochars produced by hydrothermal carbonization (HTC) of spruce bark (SB), vine shoots (VSs), and wheat straw (WSs) for removing three ...

Recent Progress on Enzyme Immobilization: Materials, Strategies, and Applications

open access: yesFood Bioengineering, EarlyView.
Enzyme immobilization technology has undergone substantial evolution driven by advances in materials science. This review systematically examines the recent advances in enzyme immobilization since 2024, with a focused analysis of five major categories of enzyme carriers including covalent organic framework, metal‐organic frameworks, polymers, carbon ...
