| abstract |
The present invention comprises the steps of: (a) preparing a mixed solution containing an inorganic precursor, a surfactant, and a photo acid generator (PAG); (b) curing the mixed solution to prepare a catalyst structure; And (c) heat-treating the catalyst structure to prepare a catalyst support. According to the present invention, by introducing a photoacid generator, the curing rate by ultraviolet (UV) rays is accelerated, a surfactant for forming pores is fixed, and the pores are prevented from collapsing, thereby having high porosity. |
