Abstract
An amino compound-supported porous substrate includes: a porous substrate including at least macropores; and an amino compound supported in at least some pores of porous substrate. Porous substrate has a total pore volume per unit volume of the porous substrate of 0.55 mL/mL or more and 0.95 mL/mL or less, as determined by mercury porosimetry. Porous substrate preferably has a skeleton containing an element selected from the group consisting of silicon, aluminum, tin, cerium, titanium, and zirconium.
