    • Organosilane-modified nanoparticles of silica, having a particle size of no more than 1 micron, in which the organosilane resides throughout the entire volume of the nanoparticles and not just at the surfaces of the nanoparticle. The nanoparticles may be in a colloidal solution. They may be prepared by hydrolyzing an alkali silicate under acidic conditions to obtain a silicic acid dispersion, followed by adding an organosilane having hydroxyl and/or hydrolyzable groups to the dispersion under acid conditions; and then raising the pH of the dispersion to at least eight to form the nanoparticles. They may be used in an effective paint primer/protective coating formulation.

    • A modified sol-gel method to create metal-rich siliceous material, such as colloidal silica or aluminosilicate particles is disclosed. Initially, the metal salt of choice is added to a silicic acid solution or a silicic acid solution containing aluminum salt. The aluminum is added to vary the metal-support interaction as it forms Al—O—Si linkages within the silica matrix. Besides aluminum, other metals can be added that form M—O—Si (M=Ti, B, etc.) linkages, which do not become reduced when treated with a reducing agent. Once the metal, silicic acid and/or aluminum salt is generated, it is subjected to colloidal growth by addition to a basic heel. Upon colloidal synthesis, the metal salt containing colloidal particle is left as is to maximize colloidal stability or is reduced with hydrazine to produce the zero valence metal-containing colloidal particle. Keeping a particle colloidal before use may be an effective method of forming a catalyst material as it can be easily spray-dried or mixed with other materials for extruded catalyst particles.
    • 公开了一种改进的溶胶 - 凝胶法制备富含硅的硅质材料,例如胶体二氧化硅或硅铝酸盐颗粒。 首先,将所选择的金属盐加入到含有铝盐的硅酸溶液或硅酸溶液中。 添加铝以改变金属 - 载体相互作用,因为它在二氧化硅基体内形成Al-O-Si键。 除了铝之外,可以加入形成M-O-Si(M = Ti,B等)键的其它金属,当用还原剂处理时,其不会降低。 一旦生成了金属,硅酸和/或铝盐,则通过加入到基础鞋跟中进行胶体生长。 在胶体合成时,含有胶体颗粒的金属盐保持原样以最大化胶体稳定性,或者用肼还原以产生含零价金属的胶体颗粒。 在使用前保持颗粒胶体可能是形成催化剂材料的有效方法,因为它可以容易地喷雾干燥或与挤出的催化剂颗粒的其它材料混合。
