High-temperature diffusion induced high activity of SBA-15 supported Ag particles for low temperature CO oxidation at room temperature

Preferential carbon monoxide oxidation on Ag/Al-SBA-15 catalysts: Effect of the Si/Al ratio

“…Our previous results show that H 2 treatment can be dispersed Ag particles and improve the catalytic activity [23,30]. Therefore, the catalytic activities of Ag/Al-SBA- 15 (200) catalysts pretreated with O 2 at 500 o C and then with H 2 at different temperatures are also tested, as shown in Fig.…”

“…Silver supported on SBA-15 and Al-SBA-15 supports were prepared by the same method as that previously reported [23,30]. Support was immersed with a certain amount of …”

Role of the support on the behavior of Ag-based catalysts for NH 3 selective catalytic oxidation (NH 3 -SCO)

“…Ag based catalysts have attracted widespread interest because of their unique properties for a variety of applications, such as the selective catalytic oxidation (SCO) of NH 3 [1], CO oxidation [2,3], catalytic oxidation of toluene [4,5], HCHO oxidation [6], ethylene epoxidation [7,8] and the selective catalytic reduction (SCR) of NO [9]. In low-temperature NH 3 -SCO reaction, Ag based catalyst has been proven to be one of the most active catalysts, but with a poor N 2 selectivity [10][11][12].…”

Surface properties and catalytic performance of Pt–Ag supported on silica – The effect of preparation methods

“…290 nm is recorded for both above mentioned bimetallic materials. It can correspond to different cationic species made with both, platinum and silver [46][47][48][49][50].…”
