Non precious metal catalysts
Non precious metal catalysts refer to catalytic materials that do not contain expensive metals such as platinum, palladium, gold, etc., and are mainly made of common transition metals and their compounds such as iron, cobalt, nickel, copper, etc. The core advantages are low cost and abundant resources. Currently, they have been widely used in fields such as hydrogen production, fuel cells, exhaust gas treatment, and chemical synthesis. Non precious metal catalysts have good economic efficiency, but their performance needs to be improved. In practical applications, it is necessary to comprehensively consider factors such as reaction requirements, economy, and sustainability. With the development of materials science and catalytic theory, both types of catalysts will continue to optimize and innovate, providing more solutions for green chemistry and sustainable development.
Common specifications:100x100x50mm
Product Introduction
Non precious metal catalysts consist of transition metals such as iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), or non-metallic elements such as sulfur (S) and phosphorus (P) as active components, often existing in the form of oxides, sulfides, or molecular sieves. This type of catalyst has a wide range of raw materials and low cost, but the active site structure is usually more complex.
- Moderate activity: usually requires higher temperature or pressure to achieve ideal activity
- General selectivity: relatively more side reactions and lower product purity
- Limited stability: susceptible to the influence of reaction environment, weak anti poisoning ability
- Poor thermal stability: sintering deactivation is prone to occur under high temperature conditions
- Environmental governance: Low temperature SCR denitrification (such as MnOx/TiO ₂ catalyst can efficiently remove NOx at 150-250 ℃), catalytic combustion treatment of industrial waste gas.
- Energy and chemical industry: Fischer Tropsch synthesis for producing clean fuels and biomass gasification for producing synthesis gas in coal chemical industry; Hydrogen production reactions in the field of new energy, such as the use of Fe Co based catalysts for water splitting to produce hydrogen.
- Petroleum refining: Replacing precious metal components in hydrocracking and refining processes to reduce costs.
- Organic synthesis: Preparation of chemical intermediates through catalytic oxidation and hydrogenation reactions (such as Cu Zn Al catalysts used for methanol synthesis).
- Pre treatment: Activation (such as H ₂ reduction or air oxidation) is required before use to expose active sites.
- Reaction conditions: Temperature, pressure, airspeed and other parameters need to be controlled (for example, in WGS reaction, temperature needs to be optimized within 200-400 ℃).
- Regeneration technology: Inactivated catalysts can be regenerated through methods such as oxidation burning and acid washing to extend their service life.
