A novel net‐like silica material with double mesoporous structure had been synthesised by one‐pot hydrothermal synthesis method. In the synthesis process, pluronic copolymer P123 (EO 20 PO 70 EO 20 ) and non‐ionic surfactant OP‐10 were used as templates and potassium fluoride (KF) was chosen as the additive. A study was carried out by small‐angle X‐ray scattering, scanning electron microscopy and transmission electron microscopy for the physical properties of the resultant products. It was found that the net‐like silica materials exhibited a unique three‐dimensional morphology with the addition of KF and preserved mesoporous structure. Moreover, the samples had double mesopores of 3.6 and 6.5 nm by the result of the nitrogen adsorption isotherm.
