摘要：
The adsorption of glycine on amorphous silica surface has been studied to demonstrate the catalytic ac-tivity of silica surfaces towards the formation of peptide bonds on prebiotic earth. Silica nanoparticles were synthe-sized using a microwave assisted method and the nanopar-ticles were characterized using SEM. Glycine was ad -sorbed from aqueous solution on the nanoparticles and the adsorption behavior was characterized using FTIR and TGA analyses. At a glycine concentration of 0.5M and at pH=7, favorable adsorption was observed which obeyed the Langmuir isotherm model. From the FTIR characteri-zation, peptide bond formation was confirmed. It was concluded that the adsorption of glycine occurs via elec-trostatic interactions as well as hydrogen bonding between the silica surface and glycine molecules.
