Approximately 60 percent of the boron produced is used in the manufacture of glass, glass fibers, and insulation. The largest use of rare earth metals is in the manufacture of catalysts for chemical processes. Rare earths are also used as a glass additive, as phosphors in laser crystals, and...
aConnect a device in DFU mode 连接一个设备在DFU方式下[translate] aSulfonic acid groups functionalized ionic liquids were one of the most useful functional ILs, which were very effective for many acids-catalytic reactions and showed even higher activities than the homogeneous catalysts such as sulfur...
The principles of green chemistry can be achieved by the use environmental friendly, harmless, reproducible and solvents and catalysts during production of medicine, and in researches. The use of UV-energy Microwave irradiation in is also significant way to achieve the goal of green chemistry. This...
Metals such as vanadium, nickel, and iron are useful as catalysts. Elements such as nickel, manganese, and zinc are useful in the production of batteries. Many of these metals have compounds that are also useful in laboratory chemistry, such as potassium permanganate and copper sulfate.Lesson...
Titanium chlorides are used as catalysts (accelerators that speed up chemical reactions) in the manufacture of plastic polypropylene and many other organic (carbon-based) chemicals.If all that sounds a bit mundane, how about jewelry made from titanium? There's a gem called titania that's made ...
Catalysts: This type of titanium oxide also works as a supporting material for the applications of catalysts. Other major uses are the removal of harmful exhaust gas emissions in the automotive industry and the removal of nitrous oxides in power stations. Titanium Facts The body of human beings ...
conditions using metal salts such as mercury, as catalysts. In all the characteristics such as physical and chemical properties, appearance, and structure, it resembles graphite. Since it is black and flaky, it acts as a good conductor of electricity and has tightly packed sheets of linked ...
Water gas used in the synthesis of some industrial processes: To remove carbon dioxide from fuel cells. Reacted with producer gas to make fuel gas. It is used in the Fischer-Tropsch process. It is used to obtain pure hydrogen to synthesize ammonia....
In more advanced three-way converters individual catalysts accomplish reduction of each species simultaneously. Britannica Quiz Building Blocks of Everyday Objects Catalysts are either platinum-group metals or base metals such as chromium, nickel, and copper. In base-metal catalysts the active surfaces...
