Abstract: It is provided a method for obtaining mesoporous silica particles with surface functionalisation comprising the steps of a) providing solutions of at least three precursors; wherein the pH of the mixture is adjusted to a range between 2 and 8 in a buffered system; b) Mixing the precursor solutions thereby allowing a reaction to take place at a temperature between 20 and 60° C., whereby surface functionalized mesoporous silica particles as solid reaction product are formed; c) Separating the surface functionalized mesoporous silica particles from the reaction mixture by centrifugation or filtration; d) Removing any pore structure directing agent present in the pores of the formed surface functionalized mesoporous silica particles by ultrasonication; e) followed by separation by centrifugation or filtration, washing and drying of the surface functionalized mesoporous silica particles.

Abstract: A method for obtaining metal oxides supported on mesoporous silica particles includes a) providing a solution of at least one metal salt, b) providing a solution of at least one template forming agent of the general formula (I) Y3Si(CH2)n—X (I), wherein X is a complexing functional group; Y is —OH or a hydrolysable moiety selected from the group containing halogen, alkoxy, aryloxy, acyloxy, c) mixing the metal salt solution and the complex forming agent solution to obtain a metal precursor; d) adding at least one solution containing at least one pore structure directing agent to the metal precursor to obtain a metal precursor template mixture; e) adding at least one alkali silicate solution to the metal precursor template mixture at room temperature to obtain a silica-supported metal complex; and f) calcination of the silica-supported metal complex under air to obtain the supported metal oxide mesoporous silica particles.
