The Influence of Calcination Temperature and Cytotoxicity Assessment of Honeycomb Platinum-Containing Cordierite Nanocomposite Catalysts via Incipient Wetness Impregnation Process

Abstract:

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.
