Imidazole was introduced into the channels of the metal–organic framework UiO-67 using an evaporation method. The imidazole@UiO-67 composite presents a high proton conductivity of 1.44 × 10−3 S cm−1 at 120 °C under anhydrous conditions. With a low activation energy at high temperatures (0.36 eV), the hybrid material can be regarded as a superionic conductor.

Mesoporous alumina with two kinds of morphologies has been synthesized via a metal–organic framework (MOF) derived route. In this approach, alumina nanosheets and nanorolls were synthesized from two topologically identical Al-based MOFs, MIL-53 and DUT-5, using a two-step calcination procedure. The obtained mesoporous alumina exhibits high specific surface area.

By choosing Zr(Y) based metal organic frameworks (MOFs) as both precursor and porous template, mesoporous yttria stabilized zirconia (YSZ) was synthesized using a simple thermal treatment. The green YSZ derived from such MOFs exhibits both high specific surface area and oxygen ion conductivity. This MOF-based method provides a new approach to the controllable synthesis of zirconia electrolytes.

Mesoporous carbon–ZrO2 (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–ZrO2 hybrid materials are formed by carbonizing UiO-66 at 600 °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 m2 g−1, a large pore size, and pore volumes of ~9.6 nm and ~0.33 cm−3 g−1, respectively. The results also indicate that the MCZ materials have a good capacity to adsorb Congo red from an aqueous solution.

Mesoporous alumina was first synthesized using a new route by thermolysis of Al-based coordination polymer (MIL-53(Al)) at 650 °C. The synthesized materials were characterized by X-ray diffraction (XRD), transmission electron microscopic (TEM), thermogravimetric (TG), nitrogen adsorption isotherms and photoluminescence (PL) spectra measurements. The results indicate that the obtained sample has ordered porous arrangements with narrow pore-size distributions (4–15 nm) and large surface areas (198 m2 g− 1). The as-synthesized mesoporous alumina exhibits a strong visible emission around 500 nm, which is associated with the F+ center. A formation mechanism of mesopores is also suggested on the basis of open architectures of MIL-53(Al). This thermolysis method provides a new approach to synthesize mesoporous alumina with strong and stable photoluminescence by using coordination polymers.Highlights► Develop a novel route for preparing mesoporous alumina by using coordination polymers. ► Obtained alumina oxide has ordered porous and large surface areas. ► The mesoporous alumina exhibits a visible photoluminescence around 500 nm.

Ultra-long and uniform CuAlO2 nanowires were successfully synthesized within a porous anodic aluminum oxide template by means of sol–gel method at 900 °C. The results of X-Ray diffraction indicate that the obtained CuAlO2 nanowires have a single delafossite structure. The scanning electron microscopy and transmission electron microscopy show that the CuAlO2 nanowires have a uniform diameter with about 50 nm and a length up to 10 μm. Room-temperature photoluminescence measurement of nanowires exhibits an ultraviolet near-band-edge emission around 350 nm (3.54 eV).
