The development of catalysts with abundant active interfaces for superior low‐temperature catalytic CO oxidation is critical to meet increasingly rigorous emission requirements, yet still challenging. Herein, this work reports a PtCo/CoOx/Al2O3 catalyst with PtCo clusters and enriched Pt─O─Co interfaces induced by hydrogen spillover from the Pt sites and self‐oxidation process in air, exhibiting excellent...
Bismuth chalcogenides are used as cathode materials in Zn‐proton hybrid ion batteries, which exhibit an ultraflat discharge plateau that is favorable for practical applications. Unfortunately, their capacity is not competitive, and their charge storage mechanisms are ambiguous, both of which hinder their further development. In this study, S‐doped Bi2Te3−x (SBT) nanosheets are prepared by tellurizing...
Lead‐free antiferroelectrics with excellent energy storage performance can become the core components of the next‐generation advanced pulse power capacitors. However, the low energy storage efficiency caused by the hysteresis of antiferroelectric‐ferroelectric transition largely limits their development toward miniaturization, lightweight, and integration. In this work, an ultrahigh recoverable energy...
Lead‐free dielectric ceramics with excellent energy‐storage performance are crucial to the development of the next‐generation advanced pulse power capacitors. However, low energy‐storage density limits the evolution of capacitors toward lightweight, miniaturization, and integration. Here, an effective strategy of constructing highly dynamic polarization heterogeneous nanoregions is proposed in lead‐free...
Single‐atom catalysts (SACs) for photocatalytic hydrogen peroxide (H2O2) generation are researched but it is still challenging to obtain high H2O2 yields. Herein, graphite carbon nitride (FeSA/CN) confined single Fe atoms with N/O coordination is prepared, and FeSA/CN shows high H2O2 production via oxalic acid and O2 activation. Under visible light illumination, the concentration of H2O2 generated...
