Hydroconversion of n-hexadecane on Pt/silica-alumina catalysts: Effect of metal loading and support acidity on bifunctional and hydrogenolytic activity

The controlled synthesis of metal-acid bifunctional catalysts: The effect of metal:acid ratio and metal-acid proximity in Pt silica-alumina catalysts for n-heptane isomerization

“…Hydroisomerization of alkanes is often conducted at higher pressures and influence of pressure on such reactions has been extensively discussed in [34]. However, study of this type of reactions at atmospheric pressure for lower molecular weight alkanes and especially for n-heptane or n-hexane is also common [1,16,35,36] and in one of these studies the authors were able to successfully demonstrate the role of Pt location related to the acid sites [35]. 0.2 g of catalyst powder was supported by quartz wool.…”

The controlled synthesis of metal-acid bifunctional catalysts: Selective Pt deposition and nanoparticle synthesis on amorphous aluminosilicates

“…Noble metals (e.g., Pt) deposited on aluminosilicates are widely studied as metal-acid bifunctional catalysts where aluminosilicates supply the acid function and noble metal nanoparticles provide a dehydrogenating/hydrogenating function [3][4][5][6][7]. In this domain the focus has recently been mostly directed towards testing new materials with different structures, acid strength and composition [8][9][10][11][12][13][14][15]. However, the synergy by menas of balance and proximity between these two types of active sites is often ignored partly due to the lack of control during catalyst synthesis [16][17][18][19].…”

Catalytic oxidation of benzene over MnO x /TiO 2 catalysts and the mechanism study

“…In recent years, numerous catalysts have been explored, including noble metals [6][7][8]and transition-metal oxides [9][10][11][12][13][14][15][16][17][18][19]. The noble metal catalysts such as Pd and Pt-based catalysts have attracted increasing attention for their excellent catalytic activities.…”
