Overview of cadmium sulfide CdS stand for cadmium sulfide, which is an inorganic substance. The α-form is lemon-yellow powder, and the β-form is orange-red powdery crystals. , Glass glaze, enamel, luminescent materials, pigments.
What is the use of cadmium sulfide? 1. Cadmium yellow is widely used for the coloring of enamel, glass, ceramics, plastics and paint. 2. Used in paint and plastic industries, and also used as an electronic fluorescent material. 3. Cadmium yellow is suitable for coloring almost all resins and is translucent in plastics. 4. As an excellent photographic developer, CdSnanoparticles can be used to detect cancer and other diseases and treat cancer cells. 5. CdS nanoparticles can be used to study the antibacterial and antifungal biological activities of various food-borne bacteria and fungi. Cadmium sulfide is mainly used as a pigment. Cadmium sulfide and cadmium selenide are used in the manufacture of photoresistors, solar cells, photocatalysts, etc. The light-colored cadmium yellow containing zinc sulfide is used in polyethylene, and the molding and processing time should be shortened as much as possible because zinc sulfide will promote the decomposition of polyethylene plastic and make it green. Cadmium yellow is not as stable as cadmium red in the room, and it is mostly used in indoor plastic products. Cadmium yellow should not be combined with pigments containing copper or copper salts, so as to avoid the formation of black copper sulfide or green copper sulfate. Cadmium yellow and blue pigments can be mixed together to get green.
Is cadmium sulfide poisonous? Cadmium sulfide is toxic, especially when inhaled as dust. Generally speaking, cadmium compounds are classified as carcinogens. When CdS is used as a color in tattoos, biocompatibility issues have been reported. What are the storage conditions of CdS powder? A humid environment can cause the powder to agglomerate, so cadmium sulfide powder needs to be vacuum-packed in isolation from air and stored in a cool and dry room.
Packaging and transportation of cadmium sulfide CdS powder: Packing: vacuum packing, 100g, 500g or 1kg/bag, 25kg/drum, or according to your requirements. Transportation: Once the payment receipt is received, it can be shipped out by sea, air, or express as soon as possible. Different specifications and prices are different, you can directly consult through the following methods.
Scientists achieve highly selective conversion of carbon dioxide Carbon dioxide conversion technology can not only reduce the concentration of carbon dioxide in the atmosphere but also obtain many high value-added carbon-based fuels. The electrocatalytic carbon dioxide reduction technology has the advantages that it can be carried out at normal temperature and pressure, can realize the artificial closed carbon cycle, etc., and provides a promising method for the current utilization of renewable energy and chemical fuel synthesis. Through the rational design and controllable synthesis of more efficient catalysts, combined with the understanding of catalytic mechanisms, it has become a research focus and difficult to realize the industrial application of carbon dioxide electroreduction technology. The researchers proposed that the "near neighbor effect" of the nano-needle tip promotes the electro-reduction process of carbon dioxide. Through the high-throughput screening of the intelligent microwave reactor, the cadmium sulfide nano-needle array structure was prepared. The study found that as the distance between the needle tips gradually decreases, the potassium ion enrichment will continue to increase. Flow electrolytic cell tests show that the performance of this multi-nano-tip cadmium sulfide catalyst is much better than other transition metal chalcogenide electrocatalysts due to the "near neighbor enrichment effect".
