The PCT-SAC-200 is an atomic-level precision preparation platform for advanced catalytic materials, enabling controllablepreparation and loading of single atoms, sub-nanometer clusters and nanoparticles. Using plasma-assisted atomization and deposition, the system precisely regulates the size, composition, dispersion and loading of active components, achieving continuous construction from single atoms to nanoparticles. The platform is suitable for the development of single-atom catalysts, dual-atom catalysts, high-entropy catalysts and highly dispersed metal materials, providing a reliable materials preparation approach for studying active-site structures, structure-performance relationships and reaction mechanisms, with wide application in energy catalysis, electrocatalysis and environmental catalysis research.

• Atomic-level control: continuous, controllable preparation of single atoms, sub-nanometer clusters and nanoparticles.
• Precise loading: tunable active-component size, composition, dispersion and loading improve material preparation consistency.
• Multi-system compatibility: suitable for single-atom, dual-atom, high-entropy and highly dispersed metal catalystdevelopment.
