In the current work we report a simple and scalable technique for synthesis of ordered nanoporous Si-ZrO composite derived from the diatom . The composite was well characterized using SEM, TEM-EDX, FTIR, TGA, BET and DLS. The diatom-ZrO was found to have a specific surface area of 140 m/g, Si:Zr ratio of 1:4 and a particle size of 80 ± 2 nm.

In addition, a composite of zirconia-iron mixed oxide loaded on activated carbon (FeZr-AC) was also synthesized. The materials were characterized using SEM-EDX, HRTEM, FTIR, Raman spectroscopy, TGA and XRD.
