Fabrication of Hollow Nanocones Membrane with an Extraordinary Surface Area as CO2 Sucker

Abstract

Recently, more and more attention has been paid to the development of eco-friendly solid sorbents that are cost-effective, noncorrosive, have a high gas capacity, and have low renewable energy for CO2 capture. Here, we claimed the fabrication of a three-dimensional (3D) film of hollow nanocones with a large surface area (949.5 m2/g), a large contact angle of 136.3°, and high surface energy. The synthetic technique is based on an electrochemical polymerization process followed by a novel and simple strategy for pulling off the formed layers as a membrane. Although the polymer-coated substrates were reported previously, the membrane formation has not been reported elsewhere. The detachable capability of the manufactured layer as a membrane braked the previous boundaries and allows the membrane’s uses in a wide range of applications. This 3D hollow nanocones membrane offer advantages over conventional ones in that they combine a π-electron-rich (aromatic ring), hydrophobicity, a large surface area, multiple amino groups, and a large pore volume. These substantial features are vital for CO2 capturing and storage. Furthermore, the hydrophobicity characteristic and application of the formed polymer as a CO2 sucker were investigated. These results demonstrated the potential of the synthesized 3D hollow polymer to be used for CO2 capturing with a gas capacity of about 68 mg/g and regeneration ability without the need for heat up.

Conducting Polymer-based Biohybrid Materials : Towards Microphysiological Chips and Soft Actuators for Bone Tissue Engineering

“…[42] Beyond ITO, low resistivity (i.e., high conductivity) electrodes prepared by the deposition of a certain thickness of noble metals (e.g., Au, Pt) on glass, silicon have been used. [43] El-Said et al [44] investigated the effect of the chemical composition of the used supporting substrate on the film morphology and adhesion of electropolymerised PPy using several hard conductive substrates including bare ITO, Au/ITO, Au-coated glass, and stainless steel (St.St.). The digital image in Figure 2.5 demonstrates that the PPy layer has better adhesion on Au-coated glass, Au/ITO and St.St.…”

Electrochemical Sensing of Dopamine Using Polypyrrole/Molybdenum Oxide Bilayer-Modified ITO Electrode

“…Conducting polymers are widely utilized for developing several electrochemical sensors because of their higher conductivity, doping and de-doping processes, cost-effectiveness, biocompatibility, and multifunctional features [ 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 ]. A polymer-incorporated nanomaterial could increase the strength of the electrochemical transmission nanocomposites based on metal oxide/CuO [ 57 ].…”

“…Another experimental research study documented the creation of a novel three-dimensional (3D) polypyrrole nanocone membrane, which boasted an exceptionally large surface area of Frontiers in Chemistry frontiersin.org 949.5 m 2 /g -surpassing all previously reported data (El-Said et al, 2022). The researchers employed a straightforward, in situ, template-free electrochemical technique to fabricate the nanocone membrane, without requiring a highly alkaline environment.…”
