Hollow nanostructured hosts are important scaffolds to achieve high sulfur loading, fast charge transfer, and conspicuous restraint of lithium polysulfides (LiPSs) shuttling in lithium‐sulfur (Li‐S) batteries. However, developing high‐efficiency hollow hosts for improving utilization and conversion of aggregated sulfur in the hollow chamber remains a longstanding challenge. Herein, hollow N‐doped...
Metal nanoparticles (NPs) with <10 nm have demonstrated many novel applications including surprisingly low melting point, astonishing liquid‐like pseudoelasticity, and outstanding hydrogen evolution performance. Here, a nanoscale self‐wetting driven monatomization of Ag NPs with <5 nm on carbon nitride (CN) to fabricate Ag single‐atom catalyst (Ag1/CN SAC) is demonstrated, and a thermodynamic...
Codoping of N and O in ultrathin graphitic carbon nitride (g‐C3N4) nanosheets leads to an inner electric field. This field restrains the recombination of photogenerated carriers and, thus, enhances hydrogen evolution. The layered structure of codoped g‐C3N4 nanosheets (N‐O‐CNNS) not only provides abundant sites of contact with the reaction medium, but also decreases the distance over which the photogenerated...
A modular strategy for the solubilization and protection of hydrophobic transition metal catalysts using the hydrophobic pockets of water soluble gold nanoparticles is reported. Besides preserving original catalyst activity, this encapsulation strategy provides a protective environment for the hydrophobic catalyst and brings reusability. This system provides a versatile platform for the encapsulation...
