Method for producing copper-selenide nanoparticles using flow process
A recently granted patent (Publication Number: US11897766B2) discloses a method for producing copper-selenide nanoparticles through a flow process. The method involves combining a copper starting material and a ligand to form a flowable copper precursor, suspending a selenium starting material in a liquid to form a flowable selenium precursor, and then combining these to create a flowable copper-selenium mixture in a lower-polarity solvent. By conducting a segmented flow of this mixture through heating units and isolating the nanoparticles in an oxygen-depleted environment using a deoxygenated, higher-polarity solvent, the process results in the production of copper-selenide nanoparticles.
Furthermore, the patent details various aspects of the method, including the use of a lower-polarity solvent in combining the copper starting material and ligand, the inclusion of an amine ligand in the flowable copper-selenium mixture, and the specific conditions for isolating the nanoparticles in an oxygen-depleted environment. The method also involves sparging both the copper and selenium precursors with a non-reacting gas to remove dissolved oxygen, as well as sparging the deoxygenated higher-polarity solvent to ensure the absence of oxygen during the nanoparticle precipitation process. Overall, the patented method offers a detailed and innovative approach to producing copper-selenide nanoparticles through a flow process, with specific emphasis on controlling the environment to achieve high-quality nanoparticle synthesis.
