摘要： A titania porous body is entirely formed of titania. The titania porous body includes a titania framework, first pores, and second pores. The titania framework forms a three-dimensional network structure. The first pores are opening portions of the three-dimensional structure. The second pores are disposed in a surface of the titania framework. Such a titania porous body is also referred to as a titania monolith.

摘要： The present invention provides a nanostructured titanic acid salt and a preparation process and use thereof. The process comprises preparing a dispersion containing titanium peroxy complex; slowly adding a metal compound to the dispersion containing the titanium peroxy complex to form a solution; adding an alcohol to the solution under normal temperature and normal pressure to produce the nanostructured titanic acid salt precursor precipitate in the solution, and separating the precipitate to obtain the titanic acid salt precursor; drying the precursor, and then heat treating it to obtain the nanostructured titanic acid salt product. The present invention provides a process for preparing a titanic acid salt with simple preparation process, easy control for process parameters and easy large-scale industrial production.

摘要： Porous metal oxide microspheres are prepared via a process comprising forming a liquid solution or dispersion of polydisperse polymer nanoparticles and a metal oxide; forming liquid droplets from the solution or dispersion; drying the liquid droplets to provide polymer template microspheres comprising polymer nanospheres and metal oxide; and removing the polymer nanospheres from the template microspheres to provide the porous metal oxide microspheres. The porous microspheres exhibit saturated colors and are suitable as colorants for a variety of end-uses.

摘要： The present invention generally relates to a method for preparing metal oxide nanosheets. In a preferred embodiment, graphene oxide (GO) or graphite oxide is employed as a template or structure directing agent for the formation of the metal oxide nanosheets, wherein the template is mixed with metal oxide precursor to form a metal oxide precursor-bonded template. Subsequently, the metal oxide precursor-bonded template is calcined to form the metal oxide nanosheets. The present invention also relates to a lithium-ion battery anode comprising the metal oxide nanosheets. In a further preferred embodiment, the battery anode may comprising reduced template, which is reduced graphene oxide (rGO) or reduced graphite oxide.

摘要： A process for producing a particulate TiO2 includes supplementing metatitanic acid with an alkali compound in a quantity of 1200 ppm to 2400 ppm of alkali, with a phosphorus compound in a quantity of 0.1 wt.-% to 0.3 wt.-% by weight of P, expressed as phosphorus, and with an aluminum compound in a quantity of 1 ppm to 1000 ppm of Al, expressed as Al, to obtain a mixture. The quantity of the alkali compound, of the phosphorus compound, and of the aluminum compound are with respect to the TiO2 content. The mixture is calcined at a constant temperature of 940° C. to 1020° C. until a numerical fraction X50 of TiO2 has a primary crystallite size of at least 200 nm, to obtain a calcined mixture. The calcined mixture is cooled to obtain a cooled calcined mixture. The cooled calcined mixture is grinded to obtain the particulate TiO2.

摘要： The present invention provides titania particles which are formed by providing a titania sol and spray drying the titania sol. A morphology of the dried titania particles is controlled by producing the titania sol from a TiO2 containing slurry and controlling the pH of the slurry to be 3 pH units or more from the iso-electric point of the titania by adding a peptizing agent to reduce an extent to which the titania sol is flocculated, or by producing the titania sol from a TiO2 containing slurry and adjusting the iso-electric point to be 3 pH units or more from the pH of the slurry by adding a dispersant to reduce an extent to which the titania sol is flocculated. The titania particles have a continuous exterior convex surface, a diameter of 30 μm or less, a BET specific surface area of 50 m2/g or more, and are porous.
