Abstract:
The adsorption layer of aerosol microparticles from cassiterite mainly containing tin dioxide is studied under ambient conditions, as well as the kinetics of dark and photoinduced processes. The quantum yield of carbon dioxide photodesorption is estimated and its spectral dependence is derived. Carbon dioxide photodesorption is observed in the intrinsic absorption region of tin dioxide; it is one of the stages of carbon monoxide photocatalytic reaction.
Keywords:
cassiterite mineral, precipitated aerosol, ambient air, composition of adsorbed layer, photodesorption, quantum yield
