Abstract
The adsorption and photosorption properties of plasmatronic ZnO particles under ambient air are investigated. The composition analysis of surface layer adsorbed on microparticles is carried out. The kinetics of desorption and adsorption processes on microparticle surfaces under darkness and illumination are studied. The quantum yield and spectral dependency of quantum yield of NO photoadsorption are determined.
