TiO2-based materials are considered to be the promising anodes of sodium-ion batteries (NIBs) because of their high safety and good stability. However, their low specific capacity and high safety operating voltage plateau impose a severe challenge for high energy density batteries. Herein, interconnected micro-sheets consisting of carbon nanotubes and sulfur doped TiO2 (CNT/S-TiO2) are synthesized via an ultrasonic process and subsequent calcination, enabling the fabrication of high-performance ...

JetBlue passengers are allowed one carry-on bag and one personal item while they fly. But that’s only if they opt for Blue, Blue Etra, Blue Plus, or Mint tickets.

Photocatalytic CO2 reduction into valuable fuel and chemical production has been regarded as a prospective strategy for tackling with the issues of the increasing of greenhouse gases and shortage of sustainable energy. A composite photocatalysis system employing a semiconductor enriched with oxygen vacancy and coupled with metallic cocatalyst can facilitate charge separation and transfer electrons. In this work, mesoporous TiO2 and titanium-based perovskite oxides (BaTiO3 and SrTiO3) nanoparticl...

Fast charging and high volumetric capacity are two of the critical demands for sodium-ion batteries (SIBs). Although nanostructured materials achieve outstanding rate performance, they suffer from low tap density and small volumetric capacity. Therefore, how to realize large volumetric capacity and high tap density simultaneously is very challenging. Here, N/F co-doped TiO2/carbon microspheres (NF-TiO2/C) are synthesized to achieve both of them. Theoretical calculations reveal that N and F co-do...

Abstract A facile synthesis of Ag nanocrystals encapsulated in nitrogen-doped carbon fiber (NCF) is proposed, based on the simultaneous reaction between pyrrole and Ag ions in an aqueous solvent followed by a heat treatment. The as-prepared Ag/NCF demonstrated superior catalytic behavior toward ORR and OER. Besides improved cycling stability, a much lower discharge/charge gap of 0.89 V (vs Li/Li ) compared with 1.38 V for NCF cathode with a fixed capacity of 500 mAh g was obtained in lithium ...

Abstract N-doped TiO , denoted as T_400, was prepared simply by the facile thermal hydrolysis of TiOSO using NH OH as both a precipitating agent and a nitrogen source. Compared to TiO without nitrogen doping, T_400 provides superior photocatalytic activity toward the selective oxidation of benzyl alcohol and benzylamine under visible light irradiation, with > 85 % conversion and > 95 % selectivity to benzaldehyde and N-benzylidenebenzylamine products, respectively. The increased photoactivity...
