TL;DR: A new metalloporphyrin-based conjugated microporous polymer, NiP-CMP, was constructed via a homo-coupling polymerization reaction and exhibits outstanding performance for the reversible adsorption of iodine in solution.

TL;DR: In this article, the reaction was studied by a pulse technique using a CH4/CO2 ratio close to one, and the solids were characterized by X-ray diffraction (XRD), BET surface area, temperature-programmed reduction and oxidation (TPR-TPO), and scanning electronic microscopy (SEM).

TL;DR: The catalytic efficiency of iron (II, III) oxide to promote Fenton-like reaction was examined by employing Rhodamine B (RhB) as a model compound at neutral pH and results indicated that surface complexation reaction may take place in the system.

TL;DR: In this article, a sub-pilot scale process of synthesis of Na-P1 zeolite from coal fly ash was presented, which has a specific BET surface area (88 m2/g) c.a. six times higher than the fly ash from which it has been derived.
Abstract: This paper presents a sub-pilot scale process of synthesis of Na-P1 zeolite from the coal fly ash. After establishing the appropriate synthesis conditions (20 kg of fly ash, 12 kg of NaOH, 90 dm3 of water, the reaction temperature: 80 °C and reaction time: 36 h), the high-purity (81 wt%) Na-P1 zeolite product was obtained. Its chemical, mineralogical, and textural properties were determined (by means of XRD, XRF, SEM–EDS and ASAP 2020). The synthesized material has a specific BET surface area (88 m2/g) c.a. six times higher than the fly ash from which it has been derived (15 m2/g). The pore-size distribution indicates a mesoporous character of the obtained zeolite, with the following pores size contents: micropores (2.76 %), mesopores (61.81 %), and macropores (35.43 %). The presented technological/production line is fully automated and allows to regulate the conditions of the synthesis process, therefore different types of zeolite materials (including: Na-X, Linde-A, and Na-P1) can be obtained using the same equipment.
