Hetero‐Polyatomic Phosphorous Anion‐Based High‐Entropy Electrocatalyst for Efficient Bifunctional Water Electrolysis in Anion Exchange Membrane Water Electrolyzers

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study aims to propose and design a highly active and durable bifunctional hetero‐polyatomic phosphorous anions‐based electrocatalyst (CoFeNiMoTiPi) featuring an amorphous, porous structure synthesized via a simple hierarchical hybrid approach based on a combination of electrochemical deposition.

Light‐Induced Structural Reorganization of Fe Centers Unlocks High Efficiency of Visible‐Light Photo‐Fenton Water Cleaning Catalyst

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Bimetallic Cu and Fe oxide species supported on porous silica with interparticle mesoporosity act as efficient photo‐Fenton‐like catalysts under visible light. Photogenerated electrons drive the Cu2+/Cu1+ redox cycle. Part of Cu1+ is responsible for the regeneration of the Fe3+/Fe2+ cycle at neutral pH. Light irradiation additionally induces structural

Origin of Physicochemical and Mechanical Stability of Low‐Temperature Prepared TiO2‐Based Photocatalytic Films: Surface Hydroxyl Density Matching

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Material science advances show how surface chemistry improves low‐temperature prepared TiO2‐SiO2 composite films. Using a colloidal‐based synthesis method instead of a powdered‐based one, researchers exploit hydroxyl groups' interfacial interactions to create nanoscale structures with superior physicochemical and mechanical stability.

Layer Geometry Modulation in Cu(II) Coordination Networks Based on Disubstituted Bis(imidazolyl)benzene Ligands

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Cu(II)‐based two‐dimensional coordination networks constructed from bis(imidazolyl)benzene ligands show how subtle changes in counteranion identity modulate layer geometry, stacking, and stability. Single‐crystal structures combined with bulk syntheses reveal distinct packing efficiencies and framework responses to humidity, vacuum, and temperature for

Actinide 4,4′‐Bipyridine‐N,N′‐Dioxide Coordination Polymers: Cationic Framework Structures Templated by Dicyanoaurate and Tetracyanoaurate Counterions

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Th4+ or UO22+ actinides, neutral bipyridine‐N,N’‐dioxide ligands, and anionic cyanoaurate linkers are combined to generate a family of four coordination polymers. ‘Truss bridge’ and square grid cationic frameworks are yielded when using [Au(CN)2]− or [Au(CN)4]−, respectively, indicating a templating effect guided by either aurophilic interactions ...

By‐product of heparin extraction as a sustainable alternative to enhance the use of nitrogen in agriculture

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract This study evaluates the potential of a new organic fertilizer derived from porcine intestinal mucosa (designated BHE), a by‐product of the heparin extraction process, as a sustainable nitrogen (N) source for agriculture. The work was conducted in two stages: (i) chemical and spectroscopic characterization of BHE compared with poultry litter ...
