This work describes the platinum-containing cordierite nanocomposite materials were synthesized by incipient wetness impregnation process with aqueous solutions of H2PtCl6, Pd(NO3)3 and Rh(NO3)3 that were coated on cordierite ceramic honeycomb substances followed by calcinations temperature ranging from 973 to 1273 K. The nanocomposite materials were characterized by STEM, with a particle size around nanoscale particle sizes (~100 nm) with high dispersion phenomena. Further, cell cytotoxicity and the percentage cell survival was determined by using 3-(4,5-dimethylthiazol-2-yl)-5(3-carboxymethoxyphenol)-2-(4-sulfophenyl)-2H-tetrazoli um (MTS) assay on human fetal lung tissue cell (MRC-5). The experimental results show that the platrinum-containing cordierite nanocomposite materials only minor cause cytotoxicity effect in cultured human cells.
