Sulfur-containing nitrogen-rich robust hierarchically porous organic polymer for adsorptive removal of mercury: experimental and theoretical insights

Abstract

Development of an efficient and robust material for adsorptive removal of highly toxic metals like mercury from water resources is very challenging from the perspectives of hygiene and sustainable environment....

Bifunctional Metal‐free Heterogeneous Catalyst for the Synthesis of Methanol and Diols from CO2 and Epoxide

“…Porosity and BET surface area of the as synthesized polymeric materials heve been analyzed by N 2 sorption isotherm at 77 K. The N 2 sorption isotherms of both PDVTA‐1 and PDVTA‐1‐SO 3 H (Figure 3a) show a sharp uptake of N 2 in the low pressure region (P/P 0 <0.03), indicating the presence of microporosity inside the polymeric architecture [37] . Further, these isotherms indicates the presence of H4‐type hysteresis, suggesting the existence of mesoporoes.…”

“…The synthetic scheme for the sulfonated porous organic polymer PDVTA-1-SO 3 H. low pressure region (P/P 0 < 0.03), indicating the presence of microporosity inside the polymeric architecture. [37] Further, these isotherms indicates the presence of H4-type hysteresis, suggesting the existence of mesoporoes. The BET surface of the as synthesized PDVTA-1 was found to be 915 m 2 g À 1 .…”

Nanostructured micro/mesoporous graphene: removal performance of volatile organic compounds

“…8 A porous material with high adsorptive capacity is signicant for the removal of the VOCs. Porous materials, including porous carbon, 9 zeolites, 10,11 metal-organic frameworks (MOFs), 12,13 porous organic polymer networks, 14 are attracting interest for applications, such as energy storage, 15,16 catalysts, 17 especially for VOCs treatment, owing to their availability, adjustable structure, variety of forms, and large specic surface area (SSA). Carbon materials, such as activated carbon bers and carbon nanotubes, have been extensively used in adsorption because of their high stability, low density, and high SSA, which enhance the removal capacity.…”
