웹2019년 7월 1일 Although the most common support of metals for hydrogenation of hydrocarbons is alumina, silica is used in several cases. Ni and copper catalysts supported
웹This conversion is likely driven by the higher degree of covalence of silica compared with alumina, which favors lower coordination numbers. This is in line with the higher
웹2019년 5월 1일 Silica-alumina, an amorphous acid catalyst, contains both Bronsted acid sites and Lewis acid sites on the surface (Busca et al. 2019 For further increase of temperature, the
웹2020년 11월 1일 Competing models exist to explain the differences in the activity of zeolites and amorphous silica–aluminas. Some postulate that silica–alumina contains dilute zeolitic
웹This is the highest HMF yield among silica–aluminas (including ASAs with strong BAS) reported under similar conditions. This novel route for synthesizing silica–alumina catalysts with
