As an outstanding carrier material, activated carbon significantly enhances the dispersion and stability of precious metals. In catalytic reactions, noble metal particles tend to distribute uniformly across the activated carbon surface, forming nanoscale clusters. This highly dispersed structure greatly improves catalytic activity and selectivity. Compared with traditional carriers, activated carbon offers a higher specific surface area and optimized pore structure, providing more active sites and reaction pathways—directly boosting catalytic efficiency.
Additionally, activated carbon’s excellent adsorption properties help trap waste gases and harmful byproducts during catalytic reactions, reducing catalyst poisoning and deactivation. In organic synthesis, it captures impurities and organic vapors, enhancing product purity and yield. In gas-phase reactions, it adsorbs intermediates and excess reactants, minimizing side reactions and improving overall process selectivity and output.
Moreover, activated carbon can form composite catalysts with precious metals, achieving synergistic performance improvements. Its superior electrical and thermal conductivity accelerates electron transfer and heat exchange, further promoting reaction efficiency. Functional groups on the carbon surface also strengthen the bond with metal particles, enhancing catalyst stability and prolonging service life.
In summary, activated carbon plays a vital and versatile role in precious metal catalysis. It not only serves as a highly effective support material but also improves reaction purity, yield, and longevity—making it a smart choice for catalytic applications requiring precision and performance.
