Summary: | Mesoporous carbon-ZrO sub(2) (MCZ) composites are prepared using a simple thermal conversion of metal-organic frameworks (MOFs). By choosing a zirconium based MOFs, called UiO-66, as both the Zr and C precursor and the porous template, porous carbon-ZrO sub(2) hybrid materials are formed by carbonizing UiO-66 at 600 degree C in an inert atmosphere. The structure, morphology, and porosity of the products were studied using powder X-ray diffraction, transmission electron microscopy, thermogravimetry, and the BET surface area method. The obtained MCZ materials exhibit a relatively high specific surface area of ~136 m super(2) g super(-1), a large pore size, and pore volumes of ~9.6 nm and ~0.33 cm super(-3) g super(-1), respectively. The results also indicate that the MCZ materials have a good capacity to adsorb Congo red from an aqueous solution. |
