Copper nanoparticles encapsulated in a zeolitic imidazole framework ([email protected]), prepared as shown in equation 1, catalyzed the hydrogenation of aromatic aldehydes with hydrogen gas to give the corresponding alcohols in yields of 94–99% (eq. 2; 8 examples).
The [email protected] catalyst was characterized by means of XRD, XPS, AES, TEM, and HR-TEM analyses. In the hydrogenation of 5-(hydroxymethyl)furfural, the catalyst was recovered and reused four times without loss of its catalytic activity.
