What catalyzes the formation of benzonitrile from benzaldehyde?

Label:chem

Topic
Benzonitrile is formed through the ammoxidation of benzaldehyde, catalyzed by Platinum (Pt) nanoparticles on graphitic carbon nitride (PtCN), where the benzenemethanimine intermediate's presence weakens hydrogen adsorption on the Pt cocatalyst, promoting dehydrogenation.
Answer
Benzonitrile is synthesized via the ammoxidation of benzaldehyde, primarily using PtCN photocatalysts, as the Pt cocatalyst diminishes hydrogen adsorption, thereby enhancing the dehydrogenation process.
