Abstract:
1. A method of forming a silica-containing product, the method comprising: a. providing a silica-containing precursor (SCP) contained in solution; b. doping the SCP with one or more metal species; c. optionally adjusting the pH of the solution to greater than about 7 or less than about 7; d. adding an effective amount of salt to the solution so that the conductivity of the solution is greater than or equal to about 4 mS, wherein said addition occurs prior to, simultaneous with, or after the pH adjustment in step c; e. optionally filtering and drying the SCP; f. optionally reacting the dried product from step e with a functional group wherein the resultant functionalized dried product is at least one of the following: a functionalized metal oxide-doped or metal sulfide-doped silica-containing product; and g. adding the SCP to a hygroscopic solid such that the resulting product comprises the metal oxide-doped or metal sulfide-doped silica-containing product deposited on a substrate selected from hydrated alkaline earth oxide, lanthanide oxide, and combinations thereof.
