An electrolytic deposition (ED) method is proposed to fabricate monolithic catalysts and applied for nitrobenzene (NB) hydrogenation in a micropacked bed (MPB). In contrast to the particle catalysts and monolithic catalysts with a suspension circulation (SC) method, the monolithic catalysts with the ED method have better uniformity for coatings and the active component. The investigation of overall external mass transfer performance reveals that the hydrogenation in MPBs with monolithic catalysts is significantly affected by external mass transfer. The catalysts with the ED method demonstrate high activity, selectivity, and stability in NB hydrogenation, and the activity is higher than that of particle catalysts and catalysts with the SC method. This ED method is universal and applicable for a variety of coatings, including Al2O3, SiO2, CeO2, and TiO2, and can provide more efficient monolithic catalysts for improving the hydrogenation performance in MPBs.

In this study, an electrodeposition (ED) method is developed to prepare Pd/Al 2 O 3 /nickel microfoam (NMF) monolithic catalysts, which are used for hydrogenation in micropacked beds (MPBs). Compared with the sol−gel slurry circulation (SC) method, the ED method has a lower coating weight and smaller specific surface area but better uniformity for the coatings. The distribution of the coatings by ED and the active component Pd shows little difference between the outer and inner surfaces of NMFs. Because of the good uniformity, the catalysts by ED exhibit higher activity and stability in the hydrogenation of α-methylstyrene than those by SC. The overall external mass transfer performance of the catalysts is also evaluated, showing that the mass transfer performance is affected by the catalyst uniformity. The catalysts by this simple, fast, and cheap ED method can effectively enhance the hydrogenation and mass transfer performance in MPBs.
