Synthetic methodologies that allow for intentionally designed structures PtxM100-x with a specified size, composition, and inter-particle spacing are key to advancing the field of energy-related catalysis. The synthesis of these catalytic nanostructures can be carried out using well-defined polymer frameworks that selectively retain catalyst precursors. Poly(vinylpyridine), (PVP) a polymer bearing pyridine residues is capable of metal-coordination or electrostatic association with metal anions in acidic media. In this work, we explore the synthesis of cross-linked PVP colloids and block copolymer templates capable of loading with catalyst precursors (ie: PtCl62-, AuCl4-, IrCl62-). PtxM100-x. Nanoparticles were produced in PVP frameworks by both photolytic and thermal reduction methods and were analyzed via atomic force microscopy (AFM), scanning transmission electron microscopy-energy dispersive x-ray spectroscopy (STEM-EDS). Thermogravimetric infrared spectroscopy (TGA-FTIR) was used to investigate thermal and chemical properties of the materials. Elemental compositions were determined by x-ray photoelectron spectroscopy (XPS) and laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) and electrochemical measurements for electrocatalytic oxidation of alcohols were examined using cyclic voltammetry (CV). Bimetallic nanoparticles of platinum-iridium (PtxIr100-x) were synthesized on electrodes and analytical substrates via block copolymer templates for the activity of formic acid oxidation.
