Comparative studies of silver based catalysts supported on different supports for the oxidation of formaldehyde

Ag–Ni bimetallic SiBEA zeolite as an efficient catalyst of hydrodechlorination of 1,2-dichloroethane towards ethylene

“…2 TPR profile for C-Ag 2.0 SiBEA contains four reduction peaks. The low intense reduction peaks at 312 and 363 K could be assigned to reduction of well dispersed silver oxides, in agreement with earlier works on silver based catalysts [23,24].…”

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

“…The absorption band around 215 nm is assigned to the electronic transition from 4d 10 to 4d 9 5s 1 of Ag + ions highly dispersed on the supports. And this band is obviously detected in the spectra of Ag/NaY catalyst, which is due to its strong ion exchange capacity of NaY support [25][26][27]. A shoulder at 275-340 nm is observed for the four samples, which is corresponding to the oxidized silver clusters (Ag ı+ n ).…”

The improved reactivity of manganese catalysts by Ag in catalytic oxidation of toluene

“…Due to the larger negative value of its reduction potential, the reduction of MnO to form Mn metal is not observed even to a reduction temperature of 800 • C [36]. For Ag/SBA-15, a negligible reduction peak can be observed at 166 • C, which is assigned to the reduction of Ag 2 O to Ag [37].…”
