摘 要：A novel solid-gas reaction preparation technology was used to adjust the composition and microstructure of the composite crystal materials by changing the preparation parameters.Compared with the commonly used sol-gel method,acid base neutralization sedimentation method,hydrothermal method,and gas phase deposition method,the technology was relatively simplified and the elemental composition was controllable,without the use of openings and additives.A kind of multi-element composite porous metal oxide was obtained by pre-intercalation and decarburization.In order to increase the porosity of MoO3 material and promote the adsorption and diffusion of reactant molecules,the microstructure of MoO3 was studied.The preparation process of porous molybdenum trioxide by solid gas combination process was discussed,which provides an innovative idea for the design and preparation of new materials with a large specific surface area and other desirable properties.
