Catalytic Activity of Sol-Gel Metal and Metal Oxide CatalystsSurface and catalytic properties in the combustion of volatile organic compounds (VOCs) reactions of various metal and metal oxides supported catalysts have been studied. The effects of the nature of the metal, metal precursor, support, preparation procedure among others are extensively discussed.SPURN 发表于 2025-3-29 02:05:03

Hydrophobicity can be promoted either by substituting EtO.Si by phenyl-triethoxysilane in the synthesis of the mixed oxide. It can also be obtained by manipulating the acidity of the solution at the cost of a slow synthesis.majestic 发表于 2025-3-29 10:27:39

On the other hand, when dry material undergoes hydrothermal treatment before calcination, the surface area diminishes ca.100 m2/g, but the mean pore diamIOTA 发表于 2025-3-29 23:01:42
