# Catalysts & Supports Source: https://powdchem.com/products/laboratory-powders/catalysts-supports/ Page type: Material category Laboratory powders Supported catalyst and catalyst-support powder inquiries. Begin with the active component, loading, support and physical form required by the reaction. [Browse 8 materials]() [Ask about supply]() [Image: Powder material specimens; appearance reference]() ## Choose a material ### Carbon-supported catalysts Select the active metal and loading, then the carbon support and supplied treatment state. Compare activity using the same reaction and pretreatment conditions. #### Palladium on carbon powder palladium on carbon catalyst powder (Pd/C) [Selection guide]() [Ask about this material]() Pd / C #### Platinum on carbon powder platinum on carbon catalyst powder (Pt/C) [Selection guide]() [Ask about this material]() Pt / C #### Ruthenium on carbon powder ruthenium on carbon catalyst powder (Ru/C) [Selection guide]() [Ask about this material]() Ru / C #### Rhodium on carbon powder rhodium on carbon catalyst powder (Rh/C) [Selection guide]() [Ask about this material]() Rh / C ### Alumina-supported catalysts Specify metal loading and alumina support as well as loose powder form. The nickel-on-alumina combination needs an individual source check. #### Nickel on alumina powder nickel on alumina catalyst powder (Ni/Al2O3) [Selection guide]() [Ask about this material]() Ni / Al2O3 #### Platinum on alumina powder platinum on alumina catalyst powder (Pt/Al2O3) [Selection guide]() [Ask about this material]() Pt / Al2O3 ### Support powders Gamma alumina and zeolite requests start with support identity, pore structure and particle form. Add the intended catalyst preparation or reaction requirements. #### Gamma alumina support powder gamma-alumina catalyst support powder (γ-Al2O3) [Selection guide]() [Ask about this material]() Al2O3 #### Zeolite powder zeolite aluminosilicate powder (framework and cation form are grade-specific) [Selection guide]() [Ask about this material]() Aluminosilicate framework; composition varies ## Material selection guide Start with the material identity and process, then check the details on the proposed datasheet. **Active component & support** Identify the metal or active phase, target loading and support chemistry. Bare precious-metal powder is not a supported catalyst. **Physical & treatment state** State loose powder versus shaped form, particle size, pore requirements and reduced, passivated or other supplied state. **Reaction & evaluation** Describe the reaction, feed and evaluation protocol. Activity results need their pretreatment, conditions and measurement basis. ## Before you choose **Can a catalyst pellet listing establish powder availability?** No. Loose powders, extrudates, beads and monoliths are different forms. We check the requested identity and form before discussing a candidate; uncommon combinations need an individual source review. **What does this directory cover?** Catalyst equipment and treatment services are outside this powder directory. Nickel-on-alumina powder is an individual sourcing check, not a standard-availability claim. ## What to include in your request A material name or reference datasheet is enough to start. Add any requirements you already know. - Active phase, support and loading - Powder form, particle and pore requirements - Supplied treatment state and SDS - Reaction, evaluation method and sample quantity ### Quantity, samples and documents Nike has no fixed minimum order. Tell us the quantity you need; we’ll check supplier pack sizes and any minimums. We’ll check the proposed grade, sample options, delivery timing and available batch documents. Include any essential COA, TDS or SDS requirements. [How we coordinate documents]() [Samples and testing]() [Send a material request]() ## Applications to explore.
