Abstract
The disclosure provides a method of producing a mesoporous phosphate-based glass. The method comprises (a) contacting a phosphate with an alcohol and/or a glycol ether to create a reaction mixture; (b) contacting the reaction mixture with alkali metal cations and/or alkaline earth metal cations; (c) contacting the alcohol, the glycol ether or the reaction mixture with a surfactant, wherein the surfactant is configured to provide channel-like pores in the resultant mesoporous phosphate-based glass; (d) allowing the reaction mixture to gel; and (e) calcinating the gel to obtain the mesoporous phosphate-based glass.

A method of producing a mesoporous phosphate-based glass, the method comprising:
- contacting a phosphate with an alcohol and/or a glycol ether to create a reaction mixture, wherein preferably the phosphate is an ormanophosphate;
- contacting the reaction mixture with alkali metal cations and/or alkaline earth metal cations;
- contacting the alcohol, the glycol ether or the reaction mixture with a surfactant, wherein the surfactant is configured to provide channel-like pores in the resultant mesoporous phosphate-based glass;
- allowing the reaction mixture to gel;
- and
- calcinating the gel to obtain the mesoporous phosphate-based glass.
