Nanoporous sol-gel derived monoliths and methods for making nanoporous sol-gel derived monoliths are provided. The methods enable fine control over pore size and pore size distribution, e.g., so that pore sizes can be predetermined and precisely tuned over a range from 0.3 nm to about 30 nm, or over a range from about 0.3 nm to about 10 nm. The monoliths may be derived from any suitable sol-gel, but in some instances they are derived from silica sol-gels. The sol-gel derived monoliths with finely tunable pore sizes and narrow pore size distributions may be used for a variety of applications, e.g., as substrates or templates for high surface area electrodes, as substrates for high surface area sensor, or as a component in a filtration apparatus.
