Background:

Polymer single crystals offer high surface area for catalyst immobilization.
Controlling nanoparticle size and distribution is crucial for catalytic activity.
Developing recyclable and highly active catalysts is essential for industrial processes.

Purpose of the Study:

To immobilize unprotected silver nanoparticles (AgNPs) on polymer single crystals.
To investigate the catalytic activity and recyclability of the resulting nanocomposite.
To explore the influence of nanoparticle size on catalytic performance.

Main Methods:

Photogenerated chemical reduction for AgNP immobilization on polymer single crystals.
Decoration with iron oxide nanoparticles for magnetic recyclability.
Evaluation of catalytic activity and size-dependent performance.

Main Results:

Successful immobilization of AgNPs with controllable size on polymer single crystals.
Enhanced catalytic activity compared to catalysts with surface ligands.
Demonstrated size-dependent catalytic activity, with ∼1.5 nm AgNPs being most active.
Achieved magnetic recyclability up to five times with minimal activity loss.
High catalyst loading due to the high surface area to volume ratio of polymer single crystals.

Conclusions:

The AgNP-decorated polymer single crystal is a highly active and recyclable catalyst.
The catalyst's performance is influenced by silver nanoparticle size.
The magnetic recyclability and high loading make it suitable for industrial catalysis.
