In this work we report for the first time that the promotion of catalytic oxidation of toluene as a model VOC is due to the cooperative redox effect between CuO nanocrystals and finely dispersed Cu-oxo-Fe clusters on mesoporous silica with defined Fe/Cu molar ratio. This increases the number and reactivity of adsorbed electrophilic (O$^−$ and O$_2^−$) as well as nucleophilic lattice oxygen (O$^{2-}$) species at the CuO crystal and and Cu-oxo-Fe cluster interface, thus providing up to twofold enhancement in catalytic activity for total oxidation of toluene. Catalysts were prepared via direct synthesis of Fe-functionalized disordered mesoporous silica containing only isolated iron sites followed by copper addition via impregnation.}, cin = {DOOR ; HAS-User}, ddc = {540}, cid = {I:(DE-H253)HAS-User-20120731}, pnm = {899 - ohne Topic (POF3-899)}, pid = {G:(DE-HGF)POF3-899}, experiment = {EXP:(DE-H253)D-C-20150101}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000521513300024}, doi = {10.1016/j.apcatb.2020.118749}, url = {https://bib-pubdb1.desy.de/record/453853}, }
