A microreactor comprising:
- a flow path;
- a sintered silica material which defines the flow path;
- at least one pore in the sintered silica material, wherein the at least one pore has an average diameter of about 1 nm to about 100 nm;
- and
- at least one catalyst within the at least one pore.
A method of manufacturing a porous catalytic glass, the method comprising:
- providing a silicon dioxide-polyvinyl alcohol composite;
- forming a flow path in the composite;
- applying a catalyst to the flow path;
- and
- heating the silicon dioxide-polyvinyl alcohol composite to yield a porous catalytic glass.
A method of manufacturing a microreactor, the method comprising:
- providing a porous silica composite comprising an organic/inorganic interface;
- and
- molding a microstructure of a microreactor into the composite.
