The state of platinum on reforming catalysts

摘要: Abstract Platinum has been deposited on a series of silica-alumina supports with different alumina contents; the dispersion platinum is found to be constant. The catalytic activity for cyclohexane dehydrogenation increases when content decreases. tert-butanol dehydration and perylene cation formation decreases support. In contrast, number sites producing tetracyanoethylene anion increases. existence charge-transfer complex between metal oxidizing support could explain variations redox properties.
