Method for preparing quaternary sulfide quantum dot based heterojunction efficient photocatalyst

The invention relates to I-III-VI group 2 sulfide and particularly relates to an AgIn5S8-ZnS / MoS2 heterojunction composite photocatalyst prepared by utilizing a simple and rapid hydrothermal method. The AgIn5S8-ZnS / MoS2 heterojunction composite photocatalyst can be used for degrading a rhodamine B dye under visible light. The AgIn5S8-ZnS / MoS2 heterojunction composite photocatalyst is prepared by mixing and stirring AgIn5S8-ZnS nano crystals, ammonium molybdate tetrahydrate and thiourea, carrying out a hydrothermal reaction for 8 hours at 200 DEG C, and filtering, washing and drying after the reaction is finished, wherein the mass ratio of the MoS2 to the AgIn5S8-ZnS nano crystals is 1%-30%, and the optimal mass ratio of the photocatalytic performance is 5%. An experiment of degrading rhodamine B (RhB) under the visible light shows that the prepared composite photocatalyst has good photocatalytic activity.

Manufacturing method of liquid crystal display screen

The invention relates to a LCD-making method, especially a LCD-making method of packaging and making liquid crystal material by using the double-layer structure where the liquid layer is covered with polymer film and which is formed in the course that the polymer monomer is separated with the liquid crystal in the polymerization reaction during the no liquid crystal injection course of a single-basal plate. According to the requirement for device structure, it further uses the techniques of coating, splashing, photoetching, etc to complete making the liquid crystal screen. Compared with traditional liquid crystal screen making techniques, it omits the courses of making an empty box and injecting liquid crystal into the empty box. It has obvious advantage in making plastic basal boards and large-sized LCD. It can also use plastic basal plate, thus making the made liquid crystal screen very thin, and further reducing the thickness and weight of the liquid crystal screen box.
