Solid-gas Phase Preparation Method for Porous Molybdenum Trioxide

【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.更多还原
