The results of the study of stationary and relaxation characteristics of heterogeneous chemiluminescence (HCLCO + O) of such crystalophosphor catalysts as CaO-Bi and Zn2SiO4-Mn are presented. Chemiluminescence was excited by the products of the dissociation of the CO, CO2, or O2 + CO + Ar mixture. The excitation of (HCLCO + O) generally follows the Eley-Rideal mechanism, that is O + CO-L → CO2-L + hv or CO + O-L → CO2-L + hv, where L denotes a lattice. The stepwise kinetic mechanism of HCLCO + O excitation is suggested. The cross-sections and quantum yields of CO oxidation on the surface of CaO-Bi and Zn2SiO4-Mn are determined.
