The design of an efficient catalytic system with low Pt loading and excellent stability for the acidic oxygen reduction reaction is still a challenge for the extensive application of proton‐exchange membrane fuel cells. Here, a gas‐phase ordered alloying strategy is proposed to construct an effective synergistic catalytic system that blends PtM intermetallic compounds (PtM IMC, M = Fe, Cu, and Ni)...
The catalytic activity and selectivity of single‐atom sites catalysts is strongly dependent on the supports structure and central metal coordination environment. However, the further optimization of electronic configuration to improve the catalytic performance is usually hampered by the strong coordination effect between the support and metal atoms. Herein, it is discovered that enzyme‐mimicking catalytic...
The room‐temperature sodium–sulfur (RT‐Na/S) battery is one of the most promising technologies for low‐cost energy storage. However, application of RT‐Na/S batteries is currently impeded by severe shuttle effects and volume expansion that limits both energy density and cycling stability. Herein, first, the first‐principal calculation is used to find that the introduction of sulfur vacancies in MoS...
The catalytic properties of supported metal heterostructures critically depend on the design of metal sites. Although it is well‐known that the supports can influence the catalytic activities of metals, precisely regulating the metal–support interactions to achieve highly active and durable catalysts still remain challenging. Here, the authors develop a support effect in the oxide‐supported metal...
Nanomaterials with enzyme‐mimicking characteristics have engaged great awareness in various fields owing to their comparative low cost, high stability, and large‐scale preparation. However, the wide application of nanozymes is seriously restricted by the relatively low catalytic activity and poor specificity, primarily because of the inhomogeneous catalytic sites and unclear catalytic mechanisms....
Tunable underwater oil adhesion is a critical issue in interfacial science and industrial applications. Although much progress has been made to date, development of novel smart coating materials that can selectively change the wetting property at different areas is considerably scarce. Here, a simple strategy is proposed to fabricate photothermal responsive coatings, which can change the oil adhesion...
Carbon dots (CDots)‐based solid‐state luminescent materials have important applications in light‐emitting devices owing to their outstanding optical properties. However, it still remains a challenge to develop multiple‐color‐emissive solid‐state CDots, due to the serious self‐quenching of the CDots in the aggregation or solid state. Herein, a one‐step synthesis of multiple‐color‐emissive solid‐state...
Exploiting high‐performance, robust, and cost‐effective electrocatalysts for the oxygen evolution reaction (OER) is crucial for electrochemical energy storage and conversion technologies. Engineering the interfacial structure of hybrid catalysts often induces synergistically enhanced electrocatalytic performance. Herein, a new strongly coupled heterogeneous catalyst with proper interfacial structures,...
A self‐templated strategy is developed to fabricate hierarchical TiO2/SnO2 hollow spheres coated with graphitized carbon (HTSO/GC‐HSs) by combined sol–gel processes with hydrothermal treatment and calcination. The as‐prepared mesoporous HTSO/GC‐HSs present an approximate yolk‐double–shell structure, with high specific area and small nanocrystals of TiO2 and SnO2, and thus exhibit superior electrochemical...
The development of environment‐friendly and high‐performance carbon materials for energy applications has remained a great challenge. Here, a novel and facile method for synthesis of olive‐like nitrogen‐doped carbon embedded with germanium (Ge) nanoparticles using widespread and nontoxic dopamine as carbon and nitrogen precursors is demonstrated, especially by understanding the tendency of pure GeO...
