Cu nanoparticles confined within ZSM-5 derived mesoporous silica (MZ) with enhanced stability for catalytic hydrogenation of 4-nitrophenol and degradation of azo dye

Facile preparation of Co/C catalysts encapsulated in carbon and selective hydrogenation in nitroaromatic hydrocarbons

“…The selectivity of the precious metal catalysts could be obtained by the preparation of alloy catalysts. 9 Nowadays, non-precious metal catalysts, including Ni, Co, and Cu, 6,10,11 have become promising alternatives due to their low cost and potential utility. Zhang 12 et al designed and successfully prepared a range of Fe-doped ZIFs with varying morphologies by adjusting the addition of vitamin C. This method achieved the hydrogenation reaction of halogenated nitrobenzene with N 2 H 4 –H 2 O at room temperature.…”
