“…In addition, solvothermal or hydrothermal methods are usually restricted by low productivity, uneven phase formation, and high-pressure-induced safety risks . Currently, molten salt synthesis is emerging as a novel approach for the preparation of metal sulfides under ambient pressure due to its simplicity, low cost, high yield, time efficiency, and environmental friendliness . The molten ionic pool leads to a high dispersion of reactants and enhances mass transfer rates, which enables chemical reactions to be completed swiftly .…”
