Efficient ceria–silica catalysts for BTX oxidation: Probing the catalytic performance and oxygen storage

Abstract

h i g h l i g h t sCeO 2 based catalysts were prepared by impregnation method and MCM-41 supports. The method of preparation affects the dispersion/incorporation of the CeO 2 which led to higher catalytic activities. CeO 2 -MCM-41 material showed better BTX oxidation capacity.

Recent Advances in the Catalytic Oxidation of Volatile Organic Compounds: A Review Based on Pollutant Sorts and Sources

“…284 Aromatic compounds are considered to pose considerable environmental hazards and are often toxic and/or carcinogenic. 199,285 The catalytic oxidation of BTEX has extensively studied over the past two decades and a large quantity of noble metal (Pd, Pt, Au and Ag) supported catalysts, [286][287][288][289][290][291][292][293] transitional metal (Co, Mn, Cu, Cr, Ni and Ti) oxides catalysts, [294][295][296][297][298][299][300][301][302][303][304] rare earth oxide catalysts, [305][306][307] perovskite-and spinel-based oxides catalysts [308][309][310][311][312][313] and hydrotalcite derived catalysts have been developed and investigated (Tables 2 and 3).

Plasmonic catalysis with designer nanoparticles

“…For example, CeO 2 is a particularly interesting support material towards oxidation reactions in nanocatalysis to its oxygen mobility and storage properties, which can be further enhanced at the metal-support interface due to metal-support interactions that lead to the formation of Ce 3+ as well as adsorbed oxygen species (O 2− or O − ). 91,92 These species, in principle, can be activated by the LSPR excitation and lead to an increase in activities in plasmonic catalysis, such as towards oxidations. 93 Intriguingly, this has remained unexploited in plasmonic catalysis.…”

Preparation of a Series of Pd@UIO-66 by a Double-Solvent Method and Its Catalytic Performance for Toluene Oxidation

“…Volatile Organic Compounds (VOCs) are a series of substances that have a negative impact on the environment, mainly from vehicle emissions and industrial production [1][2][3][4][5]. Among many organic substances, toluene has attracted attention as one of the most widely affected volatile organic compounds [6]. Humans have already invented many methods to control them since recent decades.…”
