Plasmonic noble metal nanoparticles have emerged as a promising material in sensitizing wide-bandgap semiconductors for visible-light photocatalysis. Conventional methods constructing such heterocatalysts suffer from either poor control over the size of or inefficient charge transfer through metal/semiconductor interface, which limit their photocatalytic activity. To solve this problem, work we construct Au/TiO2 photocatalysts by depositing presynthesized colloidal Au with well-controlled...
Carbonate electrolytes have excellent chemical stability and high salt solubility, which are ideally practical choice for achieving high-energy-density sodium (Na) metal battery at room temperature. However, their application ultra-low temperature (-40 °C) is adversely affected by the instability of solid electrolyte interphase (SEI) formed decomposition difficulty desolvation. Here, we designed a novel low-temperature carbonate molecular engineering on solvation structure. The calculations...
The sodium (Na)-metal anode with high theoretical capacity and low cost is promising for construction of high-energy-density metal batteries. However, the unsatisfactory interface between Na liquid electrolyte induces tardy ion transfer kinetics dendritic growth, especially at ultralow temperature (-40 °C).

In situ gas chromatography demonstrates that modified by HZTO (HZTO@Zn) can effectively inhibit...

Abstract Hard carbon (HC) has been widely regarded as the most promising anode material for sodium‐ion batteries (SIBs) due to its decent capacity and low cost. However, poor initial Coulombic efficiency (ICE) of HC seriously hinders practical application in SIBs. Herein, pyridinic N‐doped hard polyhedra with easily accessible carbonyl groups situ coupled nanotubes are rationally synthesized via a facile pretreated zeolitic imidazolate framework (ZIFs)‐carbonization strategy. The...
Using a mixture of NaNO3 and NaF as molten salt MnSO4 AgNO3 metal precursors, 0.13 wt % Ag/Mn2O3 nanowires (0.13Ag/Mn2O3-ms) were fabricated after calcination at 420 °C for 2 h. Compared to the counterparts derived via impregnation poly(vinyl alcohol)-protected reduction routes well bulk Mn2O3-supported silver catalyst, 0.13Ag/Mn2O3-ms exhibited much higher catalytic activity toluene oxidation. At toluene/oxygen molar ratio 1/400 space velocity 40 000 mL/(g h), could be completely oxidized...
Ultrasmall gold nanoparticles (us-AuNPs, <3 nm) have been recently recognized as surprisingly active and extraordinarily effective green catalysts. Their stability against sintering during reactions, however, remains a serious issue for practical applications. Encapsulating such small in layer of porous silica can dramatically enhance the stability, but it has extremely difficult to achieve using conventional sol-gel coating methods due weak metal/oxide affinity. In this work, we address...

Potassium-ion batteries (KIBs) are promising candidates for large-scale energy storage devices due to their high density and low cost. However, the large potassium-ion radius leads its sluggish diffusion kinetics during intercalation into lattice of electrode material, resulting in pulverization poor cycle stability. Herein, vanadium trioxide anodes with different oxygen vacancy concentrations (V2O2.9, V2O2.8, V2O2.7 determined by neutron diffraction) developed KIBs. The V2O2.8 anode is...
Solid-state batteries (SSBs) have received widespread attention with their high safety and energy density characteristics. However, solid-solid contacts in the internal electrode material material/solid electrolyte (SE) interfaces, as well severe electrochemo-mechanical effects caused by stress due to volume change of active material, these problems hinder ion/electron transport within SSBs, which significantly deteriorates electrochemical performance. Applying fabrication pressures stack...
