The development of the chemical industrial improves the modern civilization.However,it is also lead to the heavy environmental pollutions.If the catalysis is the core of the chemical industry,then it will also be the core to solve the environmental problems at present people facing.It was generally accepted that the majority of environmental catalysis processes can be attributed to the heterogeneous catalysis process.In heterogeneous catalysis process,the reactants diffuse to the catalyst surface and adsorb onto it,via the formation of chemical bonds.After reaction,the products desorb from the surface and diffuse away.
