Nanoconfinement of Ultrafine Rh within RuO 2 -Modified Hollow Carbon Spheres for Efficient Methanol Electrooxidation

Y W Li, Minjie Wang, Jiaqi Shao, Huajie Huang et autres

Direct methanol fuel cells have attracted extensive research interest, yet their practical advancement remains constrained by the inadequate activity and durability of conventional platinum-based anode catalysts. In response to these limitations, here we develop a non-platinum catalyst consisting of ultrafine rhodium nanocrystals …

Preparation and Mechanism of pH-Responsive Cellulose Fabric via HRP-Catalyzed Grafting of Ferulic Acid

Jinfang Zhang, Shujun Chen, Cheng Lv, Shanshan Liu et autres

To develop a novel pH-responsive multifunctional wound dressing, this study designed a ferulic acid (FA)–cellulose-grafted polymer that leverages the pH-responsive properties of FA. This polymer enables the rapid detection of pH fluctuations in wound environments and effectively monitors acute inflammatory changes. This …

Rational Design of Nanosized Pt Immobilized on Biomass-Derived Porous Carbon for Enhanced Methanol Oxidation

Xinggang Shan, Yanan Li, Wei Feng, Jinlong Qin et autres

We present the rational design of nanosized Pt nanocrystals immobilized on biomass-derived porous carbon matrices (Pt/BPC) through a convenient and eco-friendly strategy using wheat flour as a sustainable precursor. Interestingly, the three-dimensional BPC conductive network with optimized pore geometry enables enhanced metal–support …

Palladium-Catalyzed Amino-Sulfonylation of Aryl Iodide Derivatives via the Insertion of Sulfur Dioxide: One-Pot Synthesis of Aryl Primary Sulfonamides with Thiourea Dioxides

Yong Li, Kai Cheng, Panyu Ge, Ziyi Zhou et autres

Abstract A palladium-catalyzed one-pot amino-sulfonylation of aryl iodide derivatives with thiourea dioxide, PdCl2dppf, and one-pot added hydroxylamine-O-sulfonic acid is presented. This amino-sulfonylation gave structure diversity to aryl primary sulfonamides and features good functional group compatibility, mild reaction conditions, excellent regioselectivity, and moderate …

Meso‐macroporous Carbons Decorated with Ample Nitrogen Sites as Bifunctional Catalysts in CO 2 Catalytic Conversion and Oxygen Reduction Reaction

Jing Liu, Xinggang Shan, Gangqiang Wang, Weiping Kong

Abstract Electrocatalysts are vulnerable for poisoning during the process of oxygen reduction reaction (ORR), even the air containing traces of acidic CO 2 gas, leading to low activity and durability in fuel cells. Herein, an anti‐CO 2 poisoning metal‐free carbon ORR catalysts …
