If there are some metal cobalt, aluminum, iron alloy catalyst; Cobalt oxide is also important as a catalyst for petroleum, which is indispensable for accelerating petroleum refining. Therefore, the use of cobalt oxide catalysts has become an important position in recent years. 2. Battery industry Cobalt powder has been widely used in rechargeable batteries since [...]

Properties and application of nano tin oxide

SnO2 powder is an important multifunctional material with remarkable gas sensitivity, chemical stability and excellent luminescence properties. As a basic functional material, it has a wide range of applications in gas sensitivity, humidity sensitivity and optical technology. At present, it is one of the most basic raw materials used in gas sensitive components. Nano stannic oxide has high sensitivity, selectivity and stability to H2, C2H2 and other gases. Due to the quantum size effect and surface effect, the optical properties [...]

Electrocatalyst based on nano niobium dioxide for nitrogen reduction

Ammonia is the largest chemical product produced on earth, with an annual production of more than 150 million tons, and has been synthesized by the Haber-Bosch process for more than 100 years. However, the Haber-Bosch process uses hydrogen derived from natural gas reforming to reduce nitrogen under high temperature and pressure, so it is a process with high energy consumption and CO2 emission. However, the electrochemical nitrogen reduction reaction (NRR), which directly uses water and nitrogen as raw materials [...]

Introduction to the properties and applications of nano boron nitride (BN)

Boron nitride, chemical formula BN, a non-oxide material, is the isoelectronic body of carbon (C2), its crystal structure is similar to graphite, is currently one of the more studied and applied nitride ceramic materials. According to the crystal structure type, BN mainly includes hexagonal boron nitride (H-BN), cubic boron nitride (C-BN), rhombic boron nitride (R-BN), wurtzite boron nitride (W-BN). What are the properties of boron nitride? As a structural analogue of graphite, BN has better physical and chemical properties than [...]

Preparation and synthesis of cesium carbonate

Cesium carbonate is an inorganic compound. White solid at room temperature and pressure. It is soluble in water and absorbs moisture quickly when exposed to air. Cesium carbonate aqueous solution is strongly alkaline and can react with acid to form the corresponding cesium salt and water, and release carbon dioxide. Cesium carbonate should be sealed, dried and kept separate from acid during storage. Preparation and synthesis: 1. Prepare sulfuric acid solution of cesium salt, add aluminum sulfate to it, and precipitate [...]

The main application of lithium iodide trihydrate

Lithium iodide is a colorless or white cubic crystal system. Easy deliquescence. It is known to have hydrates, halohydrates LiI·1/2H2O, monohydrates LiI·H2O, dihydrates LiI·2H2O, and trihydrates LiI·3H2O. These hydrates are usually stable (the liquid phase composition is the same as the composition of the compound when dissolved, and no decomposition occurs). Commercially available products are usually trihydrate. Lithium iodide (sanshui) : hexagonal crystal system, yellow crystal. The molecular mass is 187.89. Relative density 3.48. Melting point is 73 ℃. [...]
