MOF‐Derived Superaerophobic Ni‐CoOOH Nanosheet Anchored on Stretched Carbon via In Situ Morphology Reconstruction for Durable Oxygen Evolution

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study constructed an in situ superhydrophobic OER catalyst with excellent activity and durability. Ni‐Co expansion induced tensile strain, converting the polyhedral framework into vertical nanosheets that enhance intrinsic activity and bubble detachment.

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

ENERGY &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.

Enhanced Urea Oxidation Reaction by Mn‐Doped Nickel Hydroxide From Wastewater

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Mn incorporation modifies the hydroxide structure and modulates the electronic properties of the Ni centers, promoting the formation of catalytically active NiOOH species. Mn dopants induce a favorable electronic effect but do not directly participate in the UOR mechanism, enhancing the overall urea oxidation rate and resulting in increased hydrogen ...

Bidentate‐Ligand Molecular Bridge in NiFe‐LDH as a Dynamic Proton Relay and Electronic Modulator to Enhance the Oxygen Evolution Reaction

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
By introducing 4‐chlorobenzoic acid ligands into the interlayer of NiFe‐LDH, the carboxyl and Cl groups on either side are respectively bonded to nearby Fe atoms, yielding a stable Bridge‐Linked structure. The strong electron interaction between the ligands and metal ions suppresses metal ion leaching during the reaction process, thereby maintaining ...

High Cooling Rate for LRE123 Stoichiometry Control in Preparation of High‐Tc Bulk Superconductors

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This review presents the cooling‐rate‐control melt‐growth (CRCMG) method as an effective strategy for regulating LRE123 cation stoichiometry. By accelerating the cooling rate during crystallization, oxygen vacancies are increased in the growing lattice, which suppresses LRE3+/Ba2+ substitution and yields near‐ideal 1:2:3 stoichiometry with enhanced ...
