Pr-N-C SAC

Product Name Pr-N-C SAC Product Overview Single-atom catalysts are a class of catalysts where isolated individual atoms are uniformly dispersed on a support, with no interaction between any individual atoms. In these catalysts, active metals are uniformly dispersed as single atoms on the support, forming unique coordination environments with surrounding atoms. Common single-atom catalysts include noble metals such as Pt, Pd, Au, Ir, Ag, and Rh, as well as non-noble metals like Fe, Co, Ni, and Cu. Common supports include metallic and metal oxide materials (e.g., Fe2O3, TiO2, Al2O3) and carbon-based supports (e.g., carbon nanospheres, carbon nanofibers, graphene, metal-organic framework-derived carbon, covalent triazine frameworks, carbon nitride, and phthalocyanine-derived carbon). Preparation methods include high-temperature pyrolysis, impregnation, atomic layer deposition, metal-organic framework derivation, and electrochemical deposition. Xianfeng's single-atom catalysts are prepared by high-temperature pyrolysis of nitrogen-containing carbon organic compounds (such as urea/glucose) to obtain amorphous nitrogen-doped carbon supports, with metal atoms derived from nitrate or chloride precursors. Technical Parameter Diameter:0.5-2μm Appearance:Black powder Pr content:~3wt%(EDS) Product Features High activity: The metal atoms are highly dispersed on the support, each of which can be an active center, thus improving the activity of the catalyst. High selectivity: The reaction selectivity can be controlled by controlling the coordination environment of the metal atoms and the properties of the support. High stability: The strong interaction between the metal atoms and the support can improve the stability of the catalyst. Application Fields Energy sector: Single-atom catalysts enhance oxygen reduction efficiency in fuel cells, improving overall performance. They also accelerate hydrogen evolution reactions during water electrolysis, reducing overpotential and boosting hydrogen production. Environmental protection: These catalysts degrade organic pollutants, with iron-based single-atom catalysts effectively breaking down contaminants like phenols and dyes in wastewater treatment. Chemical production: Under mild conditions, they facilitate nitrogen hydrogenation, enhancing ammonia synthesis rates and selectivity. Petrochemicals: They efficiently remove sulfur compounds from petroleum products, lowering sulfur content. Fine chemicals: Metal-based single-atom catalysts catalyze specific organic reactions in pharmaceutical synthesis, improving both selectivity and yield.
