Реферат: The catalytic activity of the SBA-15-supported silver and/or ceria catalysts in the 4‑nitrophenol reduction under mild conditions is described. The catalysts are prepared by wetness impregnation of Pluronic P123@SBA-15 hybrid applied to stabilize small Ag and CeO2 particles. The bare SBA-15 and the catalysts on the basis thereof are characterized by N2 sorption, XRD, SAXS, TEM, UV–vis DRS, and H2-TPR. The catalysts possess high surface area (594−754 m2/g) and narrow pore size distributions (5.5–7.8 nm). Silver and ceria particles are stabilized in a highly dispersed state (predominant sizes below 5 nm) in the ordered SBA-15 structure. The Ag–CeO2/SBA-15 catalyst demonstrates the presence of the developed Ag–CeO2 interface that enhances the catalytic activity in 4-nitrophenol reduction to 4‑aminophenol (k = 0.016 s−1) at room temperature and ambient pressure due to the cooperation of silver and ceria active sites. © 2020 Elsevier B.V.
