Organic modification of nano-SiO2 particles was performed with supercritical CO2 as solvent and a titanate coupling reagent NDZ-201 as the modification reagent. The surface of the nano-SiO2 particles was changed after modification by the titanate coupling reagent from hydrophilic to hydrophobic. IR and thermo-gravimetric analyses indicate that the interaction between the titanate coupling reage...

Abstract In this paper, we successfully synthesized heterojunction manganese titanate/titanate nanoparticles (MnTiO 3 –TiO 2 NPs)-decorated carbon nanofibers (CNFs) employing the electrospinning process. The morphology, crystallinity, and chemical composition of MnTiO /TiO -decorated CNFs is characterized via SEM, FESEM, STEM, TEM EDX, XRD techniques. nanocomposite exhibits good performance for...

A comparing study on formation and microstructure features of aluminum titanate is investigated through both solid-state and sol-gel processes. Aluminum titanate formed by firing at 1350ºC and 1450ºC for 4h in solid-state process. In the sol-gel process formation of submicron sized particles is followed by addition of sucrose into the transparent sol. XRD analysis was confirmed the formation of...

Barium titanate is a member of a large family of compounds with the general formula ABO3 called perovskites, as the crystal size of barium titanate increases and at critical crystalline size crystal structure of barium titanate transformed from cubic to tetragonal. Transformation of crystal structure is also take place at Curi temperature. Cubic structure show paramagenatic behavior while tetra...

The incentive policies of new energy vehicles substantially promoted the development electrical technology and industry in China. However, environmental impact key parameters progress on battery (BEV) is uncertain, BEV matching different lithium-ion power batteries shows burdens. This study conducts a life cycle assessment (LCA) four phosphate (LFP), nickel-cobalt-manganese (NCM), lithium manga...

Layer-by-layer growth of titanate nanotubes on glass substrates was achieved by alternate layer deposition using an aqueous solution of colloidal titanate nanotubes and that of a polycation. Even a single layer thin film of titanate nanotube shows high photoinduced hydrophilicity.

Gold nanoparticles were prepared and characterized on protonated (H-form) titanate nanotubes (TiONTs) and nanowires (TiONWs). The chemical nature and morphology of gold particles were monitored by X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, X-ray diffraction (XRD) and high resolution electron microscopy (HRTEM). The optical properties of Au-containing titanate nanowires were exp...
