Process Intensification at the Nanoscale: Embedding SiC in Zeolites for Energy-Efficient Catalysis.

ABSTRACT: Microwave-absorbent materials are typically blended with low-absorption solids to improve local heating efficiency in catalytic systems. However, the mixing method has a crucial effect on the additive's heating efficiency. We report here how by embedding silicon carbide (SiC) nanoparticles in ferrierite (FER) zeolite crystals during their synthesis (FER@SiC), a 2.2-fold increase in the catalytic activity for mesitylene and benzyl alcohol alkylation was achieved compared to a physical mixture of FER and SiC nanoparticles (FER/SiC). While the properties of the zeolite in the FER@SiC hybrid and SiC-free FER zeolites are almost identical, we observed a significant increase in catalytic activity under microwave heating when SiC is present within FER crystals. This enhancement is not mirrored by
