| The development of new methods for singlet oxygen (O2(1△g)) generation is greatly significant in improving the safety and environmental adaptability and reducing the complexity of Chemical Oxygen-Iodine laser (COIL). The gas-solid reaction from solid inorganic peroxides with dry hydrogen-(deuterium) halide or halogen gases provides a new chemical source of O2(1△g) for COIL. However, the study on this new chemical source of O2(1△g) for COIL is at the beginning. It is unknown whether the new method can meet the COIL requirements. Therefore, in this paper, our experimental and theoretical studies would focus on the further understanding the performance of the chemical reactions for O2(1△g) generation using solid inorganic peroxides or superoxides as starting materials. The main results presented in this dissertation were summarized as follows:1. Two gas-solid reaction systems (including the Na2O2–Cl2 and Na2O2–HCl reaction systems) were studied in a fixed–bed reactor designed by us. The results showed that only the Na2O2–Cl2 reaction system could produce O2(1△g) which was demonstrated by the recorded emission band at 1268nm, but the processes were accompanying with a drastically strong heat release and make a high bed temperature up to 700℃which is an disadvantage for O2(1△g) generation and existence.2. Three novel reaction paths (such as the gas-solid, gas-liquid-solid, gas- liquid reaction paths) for O2(1△g) generation using solid inorganic peroxides or superoxides as starting materials were developed and studied. The spectroscopicstudy showed that the CCl4 and H2O (or D2O) which were introduced into the reaction systems could significantly promote the efficiency of O2(1△g) generation from the reaction of solid inorganic peroxides or superoxides with Cl2. It also implied that: (1) the reactivity of the five solid reactants for O2(1△g) generation could be ranked as follows: Li2O2>KO2Na2O2>SrO2>BaO2; (2) the reactivity of the two gas reactants for O2(1△g) generation could be ranked as follows: Cl2>HCl.3. The thermodynamic quantities (such as△rH and△rG) of the gas-solid reaction systems made up of all possible alkali metal(or alkaline-earth metal) peroxides (or superoxides) and all possible halogen gas and gaseous hydrogen (deuterium) halide, were calculated through the Gaussian 03 program in the level of RHF/6-31G** and RHF/Lanl2dz. The calculated results indicated that the reaction systems from alkali metal superoxides with F2 or Cl2 under a low reaction temperature and a medium reaction pressure in the range of 0 to 1 atm are favorable for O2(1△g) generation.
