Methods directed to the synthesis of metal nanoparticles are described. A formation process can be carried out at ambient temperature and pressure and includes the deposition of metal ions on a titanate carrier according to a chemical deposition process followed by exposure of the metal ions to a reducing agent. Upon the exposure, nanoparticles of the reduced metal are formed that are adhered to the titanate carrier.
