Abstract
The invention provides a method for the preparation of an amorphous silicate of at least one metal from the Group 4 of the Periodic Table of Elements with a total pore volume of at least 0.3 mL/g. The method of preparation involves the use of pore shaping conditions, which can be the use of a pore shaper and optionally an increased precipitation temperature, e.g. at least 60° C. The silicate of the invention is especially suitable in catalytic reactions such as esterifications, Michael additions, transesterifications, (ep)oxidations, hydroxylations, or in absorbance of small inorganic and organic molecules e.g. CO2 or aromatic compounds.
