Abstract:To obtain a recyclable and environmentally friendly solid
catalyst
with excellent catalytic properties and selectivity for 4-nitrophenol
(4-NP) hydrogenation, herein, covalent organic frameworks (COFs) are
used as the support. Tiny PdCo alloy particles are confined in the
pores of the COFs to acquire PdCo/COFs, with an extremely narrow PtCo
size distribution (6.28 ± 2.85 nm). The effect of Pd+Co loading
and the Pd/Co atomic ratio on the catalytic behaviors of PdCo/COFs
for 4-NP hydrogenation is explored. The a… Show more
