“…Usually, the spinel Li 4 Ti 5 O 12 anode exhibits poor cyclability and rate capability resulting from poor electron conductivity, because the electronic configuration of Ti 4+ is [Ar]3d 0 . In view of this, a porous Li 4 Ti 5 O 12 nanosheet was synthesized by using cetyltrimethylammonium bromide to control the surface morphology, which greatly reduces the charge transfer resistance, shortens the ion diffusion path, and provides more active sites for sodium storage, thus leading to a reversible specific capacities of 158.9 mAh g –1 and 123.2 mAh g –1 at 0.1 A g –1 and 0.5 A g –1 , respectively . Another approach involved the construction of composite materials.…”

Rechargeable sodium-ion batteries (SIBs) have been considered as promising energy storage devices owing to the similar "rocking chair" working mechanism as lithium-ion batteries and abundant and low-cost sodium resource. However, the large ionic radius of the Na-ion (1.07 Å) brings a key scientific challenge, restricting the development of electrode materials for SIBs, and the infeasibility of graphite and silicon in reversible Na-ion storage further promotes the investigation of advanced anode materials. Currently, the key issues facing anode materials include sluggish electrochemical kinetics and a large volume expansion. Despite these challenges, substantial conceptual and experimental progress has been made in the past. Herein, we present a brief review of the recent development of intercalation, conversion, alloying, conversion-alloying, and organic anode materials for SIBs. Starting from the historical research progress of anode electrodes, the detailed Na-ion storage mechanism is analyzed. Various optimization strategies to improve the electrochemical properties of anodes are summarized, including phase state adjustment, defect introduction, molecular engineering, nanostructure design, composite construction, heterostructure synthesis, and heteroatom doping. Furthermore, the associated merits and drawbacks of each class of material are outlined, and the challenges and possible future directions for high-performance anode materials are discussed.

“…Metal titanates (ATiO 3 , where A: Ni, Co, Zn, Mn, Mg, Fe, Ca, Ba, Sr) have been extensively studied for photooxidation applications, due to their unique physical and chemical properties. According to the literature, ATiO 3 has been prepared by various methods such as sonochemical method [12][13][14][15], precipitation method [16], sol-gel method [17][18][19], wet chemical method [20], auto-ignited combustion method [21], through conventional solid-state reaction route [22], and through hydrothermal method [23,24]. However, polyol process [25,26]-that is followed in our work-offers a low-cost and simple way of fabricating metal titanates.…”

The increasing air pollution taking place in virtue of human activity has a novel impact in our health. Heterogeneous photocatalysis is a promising way of degrading volatile organic compounds (VOCs) that makes the quest of new and improved photocatalysts of great importance. Herein, perovskite-related materials ATiO3 with A = Mg, Ni, Co, Zn were synthesized through an ethylene glycol-mediated root, with ethylene glycol being used as a solvent and ligand. Characterization techniques such as X-ray diffraction (XRD), scanning electron microscopy, and energy dispersive X-ray spectroscopy (SEM/EDX), transmission electron microscopy (TEM), UV-vis spectroscopy, Raman spectroscopy, Fourier transform infrared (FT-IR), and photoluminescence spectroscopy (PL) were used in order to confirm the structure, the nanorod morphology, their absorption in UV-vis, and the separation efficiency of photogenerated charge carriers. The highest photoactivity was observed for ZnTiO3 in which 62% of toluene was decomposed after 60 min under LED illumination (54 mW/cm2).

“…In addition, considering the use of certain toxic electrodes in LIBs and the flammability reports of certain electrolytes, it is necessary to find and develop other storage systems [12]. With its rich resources, cost advantages, and similar electrochemical performance with LIBs, sodium-ion batteries (SIBs) are considered to be the most promising new storage system for partial replacement and supplement of LIBs, and gain a place in the market of green sustainable energy [13][14][15][16].…”

As a promising cathode material for sodium-ion batteries (SIBs), Na3V2(PO4)3 (NVP), the typical NASICON (Na super-ionic conductor)-structure cathode material, has received much attention resulting from its high working potential and excellent structural stability. However, it has always suffered from low electroconductivity, which largely limits its application in SIBs. Herein, to improve the electrochemical performance, we developed potassium and chlorine co-doped Na3V2(PO4)3/carbon particles (NKVPCl/C) using a spray-drying method combined with a calcinating process and adopted them as cathode materials for SIBs. We studied in detail how K+ and Cl− affected the electrochemical performance. The NKVPCl/C-2 particles displayed a highly initial discharge capacity of 109.6 mA h g−1 at 0.2 C, and had a superior cycling stable property (nearly 100% of initial discharge capacity after 500 cycles at 5 C). The excellent electrochemical performance of NKVPCl/C can be attributed to its higher Na+ diffusion and electron conduction, which indicates that the strategy of co-doping K-Cl is an effective tactic for improving the property of NVP in SIBs.
