Preparation method of organic-inorganic hybrid transparent mesoporous gel monolith

The invention discloses a preparation method of organic-inorganic hybrid transparent mesoporous gel monolith, belongs to the technical field of mesoporous molecular sieve functional materials, and particularly relates to a preparation method of organic-inorganic hybrid transparent mesoporous gel monolith which is large in size, crack-free and optically transparent and provided with pore walls modified by ethylidene. The preparation method is characterized by comprising the following steps of: by using 1,2-bis(triethoxysilane) ethane as a single silicon source, rapidly synthesising the organic-inorganic hybrid transparent mesoporous gel monolith provided with pore walls modified by ethylidene by controlling a component proportioning ratio and the conditions of system gelation in an acidic medium taking a nonionic surfactant as a template. The preparation method of the material is simple, and easy to operate; the product is regular in shape, controllable in size, and good in heat stability and transparency; and
