Abstract
In this work, ZnO mesoporous were first time fabricated by an economic and fast sol-gel method at room temperature using 2.3-dihydroxysuccinic acid as a catalyst. The formed gel was annealed at 523, 623, 723 and 823 K for one hour. The synthesized ZnO mesoporous were characterized by different techniques. The obtained data confirmed that the prepared materials were wurtzite ZnO mesoporous with different surface area in the 109.7 to 7.48m(2)/g range and mean diameter of 16.03 to 25.03 nm after annealing at different temperature. Furthermore, the BET isotherms obtained were of type IV with a hysteresis type H-3, which are characteristics of a mesoporous material. The SEM micrographs revealed that the particles size increase with rise in annealing temperature. The vibration band of stretching mode of pure ZnO was shifted to lower wavenumber due to annealing from 523 to 823K.
