“…1. These materials are known to be very stable and have been intensively studied for a whole range of applications [13][14][15][16][17][18]. A synergic combination of experimental XRPD and EXAFS measurements and theoretical ab initio simulations proved necessary to reveal the correct geometrical structure of UiO-66, as reported by Valenzano et al [19].…”

“…[32] UiO-66 powder showed 94 % conversion with 100 % selectivity at 100°C. But, in the present case, this lower crystallinity could be positive from the point of view of its catalytic activity.…”

“…These UiO-66 samples prepared in larger batch were applied as catalysts for CO 2 cycloaddition of styrene oxide (Scheme 2). [32] UiO-66 powder showed 94 % conversion with 100 % selectivity at 100°C. In contrast, the use of ground/sieved UiO-66 pellet showed 92 % conversion after longer reaction time.…”

frameworks (MOFs) are currently attracting considerable attention as heterogeneous catalysts at moderate temperatures, mainly for liquid-phase reactions. Since structural stability is one of the major concerns for the use of MOFs in catalysis, particularly considering that frequently some of the reported MOF materials are very unstable, the interest in this area has been focused on those MOFs exhibiting the highest structural robustness, UiO-66 being among the most widely used. Two introductory sections deal with the synthesis, structure and main properties of UiO-66, including its remarkable thermal (up to 350°C) and chemical (aqueous solution in a wide pH range) stability. The main body of the review summarizes those examples of using UiO-66 in catalysis grouped according to the nature of the active sites, starting with the use of UiO-66 as Lewis acids. In this section, emphasis has been made in the recent strategies to create structural defects in a controlled way that generate Lewis acidity. Other sections cover examples illustrating substituted terephthalate as active sites and the evidence that there is a synergy between acid and basic sites in close proximity that make some of these UiO-66 with substituents at the linker to act as dual acid-base catalysts. Other sections are focused on the use of UiO-66 as hosts of metal nanoparticles, metal oxides and other host, remarking the influence that the nature of UiO-66 and the possible presence of substituents in the framework play on the activity of the incorporated guest. The last section summarizes the current state of the art in the use of UiO-66 in catalysis and provides our views on future developments regarding the application of UiO-66 in industrial processes.

“…The sorption capacity exhibited by aluminium based waterworks sludge was 32.56 mg/g (0.74 mmol/g) which was higher than carbon nitrogen enriched porous carbon used by previous workers [57]. The adsorption capacity of the sludge is comparable with activated UiO-66 [58]. However, the adsorption capacity of sludge is lower than that of DAAB and Zr-MOF [1,26].…”

Cost effective, easy to use and regenerate could be the desired properties of an adsorbent. Reusing of waste material as CO2 adsorbent can be a good alternative for solving the problem of waste disposal as well. Thus, in this study, aluminium-based drinking water treatment plant sludge as carbon dioxide adsorbent was reused. The sludge collected from a local drinking water treatment plant. It was dried and characterized using scanning electron microscope-energy disperse X-ray (SEM-EDX), Fourier transform infrared spectrometer (FTIR) and thermogravimetric analysis (TGA). Investigations of the effects of temperature, flow rate, concentration of CO2 and adsorbent dosage on CO2 adsorption capacity were performed using a fixed bed column at a pressure of 1 bar. The maximum capacity of 32.56 mg/g was found which was higher than that of some reported adsorbents.
