Chemical Kinetics

Presentation

Kinetics of homogeneous and heterogeneous reactions. Fast gas-phase reactions: homogeneous hydrocarbon oxidation. Thermal hazards of solid compounds decomposition: studies of potentially explosive organic derivatives decomposition under isothermal and non-isothermal heating regimes.
Kinetics of gas-solid interaction. Heterogeneous catalysis. Dynamics of oxide surfaces during adsorption/desorption/reaction. Role of hydration-dehydration, in relation with dynamics of surface acidity. AC electrical conductivity/dielectric measurements in operando conditions as tools for surveying adsorption/desorption/reaction on oxides. Protonic conduction. Supported catalysts. Chemical sensing with semiconductor oxides. Tin dioxide based catalytic sensors.
