Copper Selenide Powder

Cu2Se Powder is an important member of the first-order transition metal chalcogenides and has various compositions, stoichiometric and non-stoichiometric forms. Copper Selenide Powder are typical transition metal chalcogenides with various applications ranging from energy conversion/storage to biomedical treatments, e.g. lithium or sodium ion batteries, electrocatalysis, quantum dot sensitized solar cells and photothermal therapy. quantity of samples to test and measure performance, for example, thermoelectric measurements require gram-scale powders to sinter a small pellet, photovoltaic testing requires dozens of individual cells in one batch. Although various strategies, such as hydrothermal or solvothermic approaches, sonochemistry, electrochemical deposition, microwave-assisted pathway and cation exchange method, have been developed to prepare Copper Selenide Powder at the nanoscale, most methods cannot produce large-scale samples. For thermoelectric, photovoltaic or other applications. For example, the yield of Copper Selenide Powder materials prepared by hydrothermal or solvothermic approaches is limited by the volume, temperature and pressure of the Teflon-lined autoclaves, making large scale preparation difficult. Jiang et al made Cu2-xSe nanostructures from CuO and Se powder in a mixture of ethylenediamine and hydrated hydrazine at room temperature. The use of expensive and corrosive mixed solvents entails high costs. Sonochemical, electrochemical deposition and microwave assisted pathways consume energy and also experience problems in large scale preparation. For the ion exchange method, the substitution reactions between cations or anions strongly depend on the size, morphology and amount of the precursors and could not be applied for large scale preparation. An alternative approach is the high-energy ball-grinding method, which takes time and energy. Therefore, a facile large-scale synthesis of copper selenide is desirable.
