Nanochannel-based heterometallic {Zn^IIHo^III}–organic framework with high catalytic activity for the chemical fixation of CO₂

Abstract

The robust, double-walled, honeycomb material {[ZnHo(TDP)(H2O)]·2DMF·4H2O}n exhibits an excellent catalytic performance in the chemical fixation of CO2 and the efficient detection of Fe(iii) ions in aqueous solution.

Novel procedure of CO2 capture of the CaO sorbent activator on the reaction of one-part alkali-activated slag

“…3 CO 2 capture is generally based on the use of a variety of sorbents, such as inorganic chemisorbents, MOFs, and organoamine adsorbents, which exhibited high theoretical uptake capacity, excellent catalytic performances, and generated valuable byproducts respectively. 4,5 In particular, CO 2 mineral sequestration deserves special attention as it is obtained directly. Du et al 6 found CO 2 has a strong affinity with montmorillonite, indicating a potential solution for CO 2 sequestration into a deep shale reservoir.…”

Heterometallic ZnHoMOF as a Dual-Responsive Luminescence Sensor for Efficient Detection of Hippuric Acid Biomarker and Nitrofuran Antibiotics

“…ZnHoMOF was prepared according to a previously reported study [60]. In the feasible synthesis of ZnHoMOF, 0.10 mmol ZnCl 2 •H 2 O, 0.05 mmol Ho 2 O 3 , 0.06 mmol H 6 TDP, 0.2 mL concentrated HNO 3 , 2 mL H 2 O, and 7 mL DMF were mixed and thoroughly stirred in a 25 mL autoclave.…”

Nanochannel-Based Heterometallic {CoIITbIII}-Organic Framework for Fluorescence Recognition of Tryptophan and Catalytic Cycloaddition of Epoxides with CO2

“…In view of the high density metal exposure sites in the NUC-31 tubular nanochannel, which makes it potentially adsorbed to quadrupole moment target molecules, we tested the CO 2 adsorption performance of NUC-31 at 273 and 298 K. The results show that the maximum adsorption capacity of CO 2 at 273 and 298 K was 95.12 and 67.35 cm 3 ·g –1 (Figure ), respectively, which were higher than those of NUC-5 , MOF-5 , UiO-66 , NUC-30 , and so on recorded in the literature. At the same time, there is a moderate lag loop in the incomplete adsorption–desorption isotherm of CO 2 , indicating that there is a strong interaction between NUC-31 and the host and guest of CO 2 .…”
