Nanocomposite materials and methods of manufacture thereof

A method for producing a guest@nanoporous-host material comprising the steps of:

• providing a nanoporous host material comprising a plurality of pores interconnected via pore windows;
• selecting a target guest species;
• identifying a target guest precursor species;
• selecting one or more reagents;
• infiltrating the nanoporous host material with the one or more reagents form a reagent@nanoporous-host material;
• and
• infiltrating the reagent@nanoporous-host material with the target guest precursor species in a reaction environment such that a reaction occurs to form the target guest species within the pores of the nanoporous host material;
• wherein the target guest species is selected on an electrochemical potential versus pH diagram defined by a reaction environment and the target guest precursor species is identified by identifying a phase on the electrochemical potential versus pH diagram;
• wherein the one or more reagents comprise
• a redox reagent selected to adjust an electrochemical potential of the reaction environment by ΔE, where ΔE is determined as a difference in electrochemical potential operable to change the electrochemical potential of the reaction environment from a stable region of the target guest precursor species on the electrochemical potential versus pH diagram to a stable region of the target guest species on the electrochemical potential versus pH diagram.
