| Popis: | High-purity copper sulfides including CuS, Cu1.75S and Cu2S were synthesized using an easy and controllable two-step heating method in a mixed solution of ethylene glycol and triethylenetetramine. Petal-like CuS, near-spherical Cu2S, and regular hexagonal Cu1.75S were obtained by simply changing the solvent volume ratio (SVR) of the mixed solution, i.e. the phase of the products solely determined by the SVR of the solution. The influence of the solvent on the final products as well as the reaction mechanism of the system were investigated and discussed. The approach is rapid, easily scalable, and environmentally friendly. As a preliminary application demonstration, dye-sensitized solar cells were assembled using the as-synthesized copper sulfides and photoelectric conversion efficiencies up to 3.62% were achieved. |
