The sluggish kinetics of the methanol oxidation reaction (MOR) with PtRu electrocatalyst severely hinder the commercialization of direct methanol fuel cells (DMFCs). The electronic structure of Pt is of significant importance for its catalytic activity. Herein, it is reported that low‐cost fluorescent carbon dots (CDs) can regulate the behavior of the D‐band center of Pt in PtRu clusters through resonance...
With the consumption of disposable electronic devices increasing, it is meaningful but also a big challenge to develop reusable and sustainable materials to replace traditional single‐use sensors. Herein, a clever strategy for constructing a multifunctional sensor with 3R circulation (renewable, reusable, pollution‐reducing biodegradable) is presented, in which silver nanoparticles (AgNPs) with multiple...
Metallic selenides have been widely investigated as promising electrode materials for metal‐ion batteries based on their relatively high theoretical capacity. However, rapid capacity decay and structural collapse resulting from the larger‐sized Na+/K+ greatly hamper their application. Herein, a bimetallic selenide (MoSe2/CoSe2) encapsulated in nitrogen, sulfur‐codoped hollow carbon nanospheres interconnected...
Lithium–sulfur (Li–S) batteries have been disclosed as one of the most promising energy storage systems. However, the low utilization of sulfur, the detrimental shuttling behavior of polysulfides, and the sluggish kinetics in electrochemical processes, severely impede their application. Herein, 3D hierarchical nitrogen‐doped carbon nanosheets/molybdenum phosphide nanocrystal hollow nanospheres (MoP@C/N...
In article number 1902491, Yuwei Zhang, Li Niu, and co‐workers report a novel polysulfides immobilizer for Li–S batteries. 3D hierarchical nitrogen‐doped carbon nanosheets/molybdenum phosphide nanocrystal hollow nanospheres (MoP@C/N HCSs) not only provide strong physical trapping and chemical anchoring toward polysulfides, but also accelerate the kinetics of the polysulfides redox reaction and lower...
