Combustion synthesis of non-precious CuO-CeO2 nanocrystalline catalysts with enhanced catalytic activity for methane oxidation
Zedan A.F.; AlJaber A.S. ( MDPI AG , 2019 , Article)In this study, xCuO-CeO2 mixed oxide catalysts (Cu weight ratio x = 1.5, 3, 4.5, 6 and 15 wt.%) were prepared using solution combustion synthesis (SCS) and their catalytic activities towards the methane (CH4) oxidation ... -
Cu-Ce-O catalyst revisited for exceptional activity at low temperature CO oxidation reaction
Zedan A.F.; Polychronopoulou K.; Asif A.; AlQaradawi S.Y.; AlJaber A.S. ( Elsevier B.V. , 2018 , Article)In the present study, CexCu1−xO2−δ (x = 0, 0.3, 0.5, 0.8, 0.9, and 1) catalysts were synthesized using a facile and reproducible combustion method and were evaluated towards the CO oxidation (CO-OX) and CO preferential ... -
Tailoring the efficiency of an active catalyst for CO abatement through oxidation reaction: The case study of samarium-doped ceria
Polychronopoulou K.; Zedan A.F.; AlKetbi M.; Stephen S.; Ather M.; Katsiotis M.S.; Arvanitidis J.; Christofilos D.; Isakovic A.F.; AlHassan S.... more authors ... less authors ( Elsevier Ltd , 2018 , Article)In the present study, for the first time we tailored organic chemistry traditional synthesis tools towards preparation of CexSm1-xO2 (x = 0.2, 0.5, 0.8, 1) fluorite-type mixed oxides which are used for CO abatement. In ... -
Tuning the activity of Cu-containing rare earth oxide catalysts for CO oxidation reaction: Cooling while heating paradigm in microwave-assisted synthesis
AlKetbi M.; Polychronopoulou K.; Zedan A.F.; Sebastian V.; Baker M.A.; AlKhoori A.; Jaoude M.A.; Alnuaimi O.; Hinder S.S.; Tharalekshmy A.; AlJaber A.S.... more authors ... less authors ( Elsevier Ltd , 2018 , Article)(Ce-La-xCu)O2 catalysts with low (3 at.%) and high (10 at.%) Cu content were prepared by conventional microwave (MW) and enhanced microwave methods where air cooling (AC), while heating, was applied. The catalysts were ...
