Store in a sealed container in a cool, dry place away from oxidants. Avoid contact with oxides, carbon oxides. Soluble in aqua regia and molten alkali. The platinum powder with micron size is spherical and polygonal. Resistance to moisture, oxygen, acid, alkali corrosion is a non - flammable explosive. Soluble in aqua regia and molten alkali. Platinum catalyst (platinum catalyst) is the general term of a kind of catalyst made of platinum as the main active component. Using platinum net, platinum black, or platinum on aluminum oxide and other carriers, can also contain metal rhenium and other auxiliary catalyst components. It is mainly used for ammonia oxidation, petroleum hydrocarbon reforming, unsaturated compound oxidation and hydrogenation, removal of carbon monoxide and nitrogen oxides in gas and other processes. A catalyst often used in chemical, petroleum, and chemical reaction processes. It has high catalytic activity, strong selectivity, convenient preparation of catalyst and small amount of usage. The catalytic performance can be optimized by changing and improving the manufacturing method and compounding with other metals or active components of the catalyst. It has many advantages, such as wide application field, repeated regeneration and activation, long service life, and recovery and reuse of waste catalyst metal palladium. Many varieties of platinum catalyst has become a patent product, applied to all walks of life, which has the function of the new structure and catalytic platinum catalyst continues to research and development, not only the reaction process of many difficult to implement the platinum catalyst and possible, and make many petroleum and chemical industry and other industrial production processes, by using newly developed platinum catalyst to improve and improve, process simplification and enhances the economic benefit, therefore platinum catalyst still has great prospects for development.
