Bifunctional Artificial Enzymes‐Loaded Microgels With LOX‐ and CAT‐Like Activities for Metabolic Reprogramming and Scarless Wound Repair

open access: yesAdvanced Science, EarlyView.
A bifunctional lactate oxidase‐like and catalase‐like artificial enzyme (Metazyme) is integrated into a rod‐shaped microgel (MetaRgel) to enable cascade lactate oxidation and oxygen regeneration. By reprogramming the wound metabolic microenvironment, MetaRgel alleviates excessive lactate accumulation, oxidative stress, hypoxia, and inflammation ...

Atomic Tuning of Metal‐Support Interactions for Pathway‐Selective CO2 Photoreduction on TiO2

open access: yesAdvanced Science, EarlyView.
Single‐atom Fe and Cu catalysts anchored on TiO2 steer photocatalytic CO2 reduction toward distinct pathways. Fe sites favor rapid *CO desorption and selective CO formation, whereas Cu sites stabilize *CHO intermediates, enabling deep reduction and C─C coupling. Combined spectroscopy and DFT calculations reveal how metal–support interactions and oxygen

Harnessing Transformation of Metal‐Ligand Coordination in Dinuclear Ni(II)‐Schiff Base Coordination Polymer for Promoting Electrochemical Oxygen Evolution

open access: yesAdvanced Science, EarlyView.
Ni–Schiff base coordination polymer [Ni2(tmd)2]n was synthesized and applied to enhance alkaline OER by virtue of its transformation between 5‐ and 6‐coordinate Ni sites along with the spin state exchange. ABSTRACT One of the major challenges in overall water splitting is improving the sluggish kinetics of the anodic oxygen evolution reaction (OER ...

DC‐magnetometry Analytical Tool Driven by Spin Ordering Phenomena for Sensing Chemical Interactions at the Surface of Nanomaterials

open access: yesAdvanced Science, EarlyView.
The adsorption of AsV on akaganeite nanorods was found to provide a magnetic signature. A change in the surface spin order gave rise to a second peak in the zero‐field cooled curve. AsIII adsorption does not provide any change in the magnetic behavior of the sorbent.

Tuning Defects in Ni‐Doped Maghemite for Enhanced Solar Driven Oxygen Evolution: Insights From Operando X‐Ray Spectroscopies

open access: yesAdvanced Science, EarlyView.
ABSTRACT Maghemite (γ$\gamma$‐Fe2${\rm Fe}_2$O3${\rm O}_{3}$) is a promising non‐precious‐metal‐containing photocatalyst for water oxidation (OER). Despite being less studied than Hematite, it offers similar corrosion resistance and a favorable band structure, along with higher conductivity and the advantage of an adaptable spinel structure.

Dynamic Hydrogen‐Bonding Nanonetworks and Asymmetric Dual‐Interface Built‐In Electric Fields Cooperatively Mediate Proton‐Coupled Electron Transfer for C─H Activation

open access: yesAdvanced Science, EarlyView.
The general strategy for constructing proton–electron dual‐transport‐channel photocatalysts (hollow Co3S4/Sv‐chalcogenide/Ti3C2 nanoreactors) is developed. Theses ternary‐component nanoreactors feature dynamic hydrogen‐bonding nanonetworks as proton‐transport channels and asymmetric dual‐interface BIEFs as electron‐transport channels, serving as a ...
