| description | A spherical cadmium sulfide crystal and a method for preparing same. The method comprises: well mixing an aqueous solution containing a cadmium source and a sulfur source, and adding the mixed solution into a high-pressure reaction kettle; adding a surfactant into the high-pressure reaction kettle; and performing hydrothermal reaction at a temperature of 140-200ºC for 8-16 h, thus obtaining a spherical cadmium sulfide crystal. The method is simple in operation and low in costs, and is easy to control since the reaction is performed in a closed high-pressure reaction kettle. The prepared cadmium sulfide crystal is a pure hexagonal wurtzite with high degree of crystallinity. In addition, compared with cadmium sulfide crystals of other shapes, the spherical cadmium sulfide crystal has a larger specific surface area and a higher photocatalytic property.
