Furfuryl Alcohol‐Driven Proton Supply Enables Efficient Photocatalytic H2O2 Production Beyond Water‐Based Systems

Advanced Science, EarlyView.
A ZnIn2S4–carbon dot heterojunction enables photocatalytic H2O2 production coupled with furfuryl alcohol oxidation. In this redox system, furfuryl alcohol acts as both the electron donor and oxidation substrate, producing furoic acid with 100% selectivity and 98% conversion while supporting efficient H2O2 generation with a solar‐to‐chemical conversion (

Spatiotemporal Targeting Randle Cycle and Immune Checkpoint for Potent Antitumor Therapy

Advanced Science, EarlyView.
A glucose oxidase‐based nanogel (GOX‐NG) system using catechol‐functionalized alginate, exhibits enhanced tumor penetration, prolonged retention, and sustained glucose depletion in the tumor microenvironment. When combined with a fatty acid oxidation inhibitor, it implements dual metabolic suppression, thereby enhancing ROS‐induced immunogenic cell ...

Palladium/Heteropoly Acid Catalyzed Oxidative Coupling of 2-Methoxy-1,4-benzoquinone with Arenes

Journal of the Brazilian Chemical Society, 2002
Oxidative coupling of 2-methoxy-1,4-benzoquinone and arenes in acetic acid gives methoxyaryl-substituted 1,4-benzoquinones. The reaction is effectively catalyzed by a Pd(OAc)2/heteropoly acid (H9PMo6V6O40 ) redox system with dioxygen as the final oxidant.

Effects of Catalyst Synthesis Methods on the Physicochemical Properties of Silica‐Supported Au–Ru Bimetallic Catalysts and their Influence on the Oxidation of Phenols with H2O2

ChemistryOpen
Herein, silica‐supported Au–Ru catalysts with 5% loading for each metal were prepared by microwave‐assisted loading (MW) and deposition (DP) methods. Au–Ru nanoparticles are obtained on MW‐5Au5Ru while short Au–Ru nanochains are obtained on DP‐5Au5Ru ...

Interfacial Water Coordination on Ruthenium Oxide Nanoparticles Confined Within Covalent Organic Framework and Its Effect on Electrochemical Nitrate Reduction

Advanced Science, EarlyView.
We demonstrate how oxygen‐deficient ruthenium oxide (RuOx) nanoparticles confined within covalent organic framework achieve highly efficient nitrate‐to‐ammonia conversion. Strong interaction between RuOx nanoparticles and COF results in modified interfacial hydrogen‐bond water network and adsorption of nitrogenous intermediates.

Nano‐Backpack Engineered Probiotics with Reactive Oxygen Species–Responsive Tungsten Release for Synergistic Therapy of Inflammatory Bowel Disease

Advanced Science, EarlyView.
An integrated probiotic system is engineered to execute a programmed therapeutic cascade against inflammatory bowel disease. Upon pathological signals, the system sequentially performs ROS scavenging, tungsten release, and selective pathogen suppression, thereby breaking the oxidative stress–dysbiosis cycle to remodel gut microbiota and reinforce ...
