The LiClO4, Pb3 (PO4) 2 and LiClO4 · Pb3 (PO4) 2 complex catalysts were prepared. The crystal phase and surface structure of the catalysts were characterized by XRD and IR. The chemical properties of ethane The results show that the ClO and PO bond on the surface of the catalyst are the main adsorption sites for ethane.The interaction between LiClO4 and Pb3 (PO4) 2 promotes the ClO bond On the adsorption of ethane activation ability under certain reaction conditions, the conversion of ethane and the system energy utilization, the composite catalyst than pure LiClO4 and Pb3 (PO4) 2 more efficient use of laser light energy temperature LSSR response has some supporting role
