Synthesis of PbS/SiO2 Nanocomposites Using 3-Mercaptopropyltrimethoxysilane as a Bifunctional Linker Molecule and Determination of the Formation Pathway
PbS/SiO2 nanocomposites were synthesized from the co-hydrolysis and condensation of tetraethylorthosilicate (TEOS) and 3-mercaptopropyltrimethoxysilane (MPTMS) followed by the addition of lead acetate, forming precursor gels containing covalently incorporated lead thiolate complexes. Pyrolysis of the precursor silica gels in a N2 atmosphere formed PbS nanoclusters dispersed throughout a silica xerogel matrix. The formation pathway was characterized by optical absorption, powder X-ray diffraction (XRD), infrared spectroscopy (IR), and transmission electron microscopy (TEM).^
