We show that, molecular adsorption of phenol on α-Al₂O₃(0001) entails binding energies in the range of −202 kJ/mol to −127 kJ/mol. The dehydroxylated alumina catalyzes the conversion of phenol into its phenolate moiety with a modest activation energy of 48 kJ/mol. Kinetic rate parameters, established over the temperature range of 300 to 1000 K, confirm the formation of the phenolate as the preferred pathways for the adsorption of phenol on alumina surfaces, corroborating the role of particulate matter in the cooling down zone of combustion systems in the generation of EFPRs.]]> Sat 24 Mar 2018 07:30:33 AEDT ]]> Effects of particle cloud extinction on synthesis gas reduction of metal oxides in chemical looping reactors https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:23739 2O₃ metal oxides undergoing synthesis gas (syngas) reduction in chemical looping reactors were theoretically investigated using an adaptation of Semenov’s theory. The extinction was characterised in terms of a critical particle radius and a minimum percentage of the cloud mass loss (%CML). The critical sizes of metal oxide particles in the cloud were found to be strongly affected by the particle size, shape, and reactivity as well as solid volume fraction and type and concentration of the reducing gas. Our analyses indicate that blending of a base metal oxide with another metal oxide species with different reactivity may lower the extinction potential of the cloud (i.e. likelihood of extinction).]]> Sat 24 Mar 2018 07:16:56 AEDT ]]> Versatile template-free construction of hollow nanostructured CeO₂ induced by functionalized carbon materials https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:36639 Mon 22 Jun 2020 13:20:40 AEST ]]> Formation of environmentally-persistent free radicals (EPFR) on α-Al₂O₃ clusters https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:31130 Mon 11 Mar 2019 12:07:37 AEDT ]]>
