1. Oxygen Storage Chemistry of Nanoceria
Sammanfattning : The versatile redox chemistry of ceria (CeO2) originates from its Ce4f electron, which plays the key role in changing the oxidation state of Ce between +IV and +III. Ceria is, among other things, a material that can act as a powerful oxygen buffer with a high oxygen storage capacity (OSC). LÄS MER
2. Oxygen Vacancy Chemistry in Ceria
Sammanfattning : Cerium(IV) oxide (CeO2), ceria, is an active metal oxide used in solid oxide fuel cells and for the purification of exhaust gases in vehicle emissions control. Behind these technically important applications of ceria lies one overriding feature, namely ceria's exceptional reduction-oxidation properties. LÄS MER
3. Catalysts for Car Exhaust: Oxygen Storage in Platinum/Ceria and Mass Transfer in Monoliths
Sammanfattning : In this work, the oxygen storage/release in Pt/ceria catalysts has been investigated both experimentally and theoretically. Moreover, the flow distribution and mass transfer in monolith catalysts for car-exhaust purification have been studied. LÄS MER
4. Monolith catalysts for car exhaust : experimental and theoretical studies of oxygen storage, flow and mass transfer
Sammanfattning : .... LÄS MER
5. Off-gassing from thermally treated lignocellulosic biomass
Sammanfattning : Off-gassing of hazardous compounds is, together with self-heating and dust explosions, the main safety hazards within large-scale biomass storage and handling. Formation of CO, CO2, and VOCs with concurrent O2 depletion can occur to hazardous levels in enclosed stored forest products. LÄS MER
