| Effective water filtration to the purest standards is an ongoing battle for various sectors of science. A novel technology is being developed at the University of Florida that can improve the efficacy of destroying harmful organics, and simultaneously analyzing the pollutants in the process. This is achieved by the synergistic functionalities of: (1) photocatalytically active surfaces, (2) granular activated carbon for adsorption, (3) magnetic core for magnetic fluidization, and (4) silver particles for surface enhanced Raman scattering (SERS). The deposition of photocatalytic titania nanoparticles on activated carbon granules were obtained by coating via a sol-gel process. Scrutinizing various concentrations of silver nitrate solution, percent ethanol in solution, and heat treatments, allowed for the control of size and morphology of the silver particles on the activated carbon surface. A range of silver particle morphology has been found, from platelets to spheres to dodecahedrons. Assessment of the synthesized materials indicated improved functionalities. |
