Data Sheet 1_Active porous ZIF-8 based hybrid catalysts for solvent-free reactions.docx

These composites were based on porous metal–organic frameworks (MOFs), specifically the zinc-based ZIF-8, activated catalytically by the incorporation of Keggin-type phosphomolybdic acid (PMo₁₂).

The resulting composite denoted as PMo₁₂@ZIF-8 was prepared via impregnation and in-situ methods (PMo₁₂ loadings of 0.149 and 0.194 mmol/g were obtained via in-situ and impregnation procedures). Both materials were characterized by FTIR-ATR, PXRD, SEM, EDS, and ICP-OES. The catalytic performance evaluation revealed that both composites exhibited high conversion rates under a sustainable solvent-free system (98% of conversion was achieved after 24 h), and high selectivity toward 2-Amino-1,2-diphenylethanol, along with notable robustness and recyclability.</p>
