Abstract
In this research a high yield, homogenous and fast bottom-up wet-chemical method has been carried out for the synthesis of platinum nanocrystal (Pt-NC) and up to micron size (Pt-M). After synthesis of the particles, surface plasmon resonance (SPR), ultra violet (UV) spectrum, size, shape, and composition were measured for each set. Platinum nanocrystal attained by preventing particles to grow directly after reduction of Pt+4 to Pt0. Pt-NC constructed by statistic repulsion of ionic surfactant surrounded nanocrystals. The final size of the Pt-NC found to be 3.8 ± 0.72 nm. Before sonication treatment, particle size of 705.2 ± 80.3 nm was achieved. After sonication, particle size increased to 1046.1 ± 199 nm. Particles were formed in a controllable way, homogenous and mono-disperse in size and shape. It is confirmed that sonication except for the sharpness of the spectrum did not alter the peak wavelengths. The suggested synthesis method enabled cost-effective concrete control over size, shape, concentration, and time of the synthesis.Graphic abstract
