Platinum paste refers to platinum particles or granular material, typically mixed with other substances. Platinum is a rare precious metal known for its excellent chemical stability, heat resistance, and corrosion resistance, making it essential in many industrial and scientific applications. The preparation of platinum paste usually involves mixing platinum particles with other materials, such as carbon, to enhance its properties or adapt it for specific applications. In catalysts, platinum often exists in granular or nanoparticle form, which helps to increase surface area and enhance catalytic activity. The preparation methods of platinum paste may include combining platinum metal with a carrier material to form a composite, then dispersing it in a reactor. In automotive exhaust treatment, platinum paste is commonly used in three-way catalysts to help convert harmful gases, such as carbon monoxide, nitrogen oxides, and volatile organic compounds, into more environmentally friendly substances. In other fields, platinum paste is also used to facilitate chemical reactions, such as hydrogen generation and organic synthesis.

Platinum-plated nickel mesh is a material that is usually based on nickel and electrochemically coated with a layer of platinum. This platinum-plated nickel treatment gives the material the dual characteristics of platinum and nickel, combining the advantages of the two metals. Platinum has excellent corrosion resistance, catalytic properties and stability, while nickel has good conductivity and mechanical properties. This structure is designed to take advantage of the catalytic properties of platinum while reducing costs because nickel is a relatively cheap metal. Platinum has good catalytic properties in electrochemistry, so it is often used in fuel cells, electrolysis of water to produce hydrogen, electrochemical sensors and other fields. Due to the high cost of platinum, the method of platinum plating on a cheap metal substrate can reduce manufacturing costs to a certain extent while maintaining good catalytic activity. This material usually has a large specific surface area, providing more active sites to help enhance the catalytic effect. Platinum-plated nickel mesh is often used in various electrochemical devices and reactions that require efficient catalysis.

A platinum crucible is a laboratory appliance that is usually used for chemical experiments or melting metals and other substances at high temperatures. It is mainly made of platinum metal, because platinum has high temperature resistance, chemical inertness and other characteristics, suitable for working under extreme conditions. Platinum crucibles are often used in experiments that require reactions at high temperatures, such as chemical synthesis or analytical experiments at high temperatures. Platinum's high melting point (1768 degrees Celsius) and excellent corrosion resistance make platinum crucibles perform well in these applications. Platinum crucibles are usually conical or funnel-shaped containers with high temperature resistance and corrosion resistance. They can be used to heat substances, especially when high-temperature furnaces or open flames are required. Due to the high cost of platinum, platinum crucibles are generally used for experiments that require high purity and high temperature stability when high-temperature treatment of samples such as metals and ores.

Platinum-rhenium (Pt-Re) catalyst is a type of catalyst commonly used in chemical reactions to promote specific chemical changes. It primarily consists of platinum (Pt) and rhenium (Re). This catalyst is widely used in important chemical processes, and one of its common applications is in petroleum catalytic cracking (FCC). Petroleum catalytic cracking is an essential refining process that breaks down high molecular weight petroleum fractions into lower molecular weight products, such as gasoline and liquefied petroleum gas, under the influence of a catalyst. The platinum-rhenium catalyst improves the efficiency and selectivity of the cracking reactions in this process. Platinum-rhenium catalysts also exhibit excellent catalytic activity and selectivity in some reactions, especially those involving hydrogen. Their applications include hydrogenation, dehydrogenation, isomerization, and other reactions, which are significant in petroleum processing, fuel production, and organic synthesis.
