The growing concern about the environmental consequences of anthropogenic CO2 emissions significantly stimulated research low-cost, efficient, and recyclable solid adsorbents for capture. In this work, a series MgO-supported mesoporous carbon nitride with different MgO contents (xMgO/MCN) was prepared using facile process. obtained materials were tested capture from 10 vol% mixture gas N2 fixed bed adsorber at atmospheric pressure. At 25 ºC, bare MCN support unsupported samples demonstrated capacities 0.99, 0.74 mmol g-1, respectively, which lower than those xMgO/MCN composites.The incorporation into improved uptake, 20MgO/MCN exhibited highest capacity 1.15 g-1 °C. performance nanohybrid can be possibly assigned to presence high content highly dispersed NPs along its textural properties in terms specific surface area (215 m2g-1), large pore volume (0.22 cm3g-1), abundant structure. efffects temperature flow rate also investigated on 20MgO/MCN. Temperature found have negative influence 20MgO/MCN, decreased 0.65 g-1with rise C 150º C, due endothermicity Similarly, 0.54 increase 50 200 ml minute-1 respectively. Importantly, showed excellent reusability consistent over five sequential sorption-desorption cycles, suggesting suitability practical CO2.

Abstract In the current paper, a NiO nanoparticles-loaded mesoporous carbon (CMK - 3) catalyst, denoted as NiO/CMK-3, has been successfully synthesized using facile strategy. The as-prepared material characterized through XRD, Raman spectroscopy, low-temperature N 2 physisorption measurements, FTIR, FE-SEM, TEM, and XPS. as-fabricated NiO/CMK-3 catalyst manifested superior activity in NaBH 4 -assisted reduction of methylene blue (MB) dye to its colorless leuco form. Remarkably, over 99% 25 mg L −1 MB was reduced by 7.5 mM/L 0.1 g within 3 min at room temperature. Furthermore, kinetics study confirmed appropriateness pseudo-first-order kinetic model for elucidating catalyst. Importantly, maintained almost constant catalytic even after 5 times reuse reduction, demonstrating stability reusable ability. So, NiO/CMK-5 appears promising heterogeneous effective remediation dye-containing wastewater.
