Abstract
A fuel-sorbing device excellent in sorbing evaporated fuel includes a sorbent of layered porous silica for capturing evaporated fuel and a container which houses the sorbent and into which the evaporated fuel is introduced. The layered porous silica is composed of a plurality of superposed sheets made of a framework of SiO.sub.2. Adjacent sheets are partly bonded each other to form a three-dimensional framework having a large number of pores. The sorbent can be used in combination with an organic polymer sorbent, so as to sorb evaporated fuel in two stages.
