Fabrication of ordered mesoporous carbon hollow fiber membranes via a confined soft templating approach

Abstract

A new method to prepare ordered mesoporous carbon (OMC) hollow fiber membranes through a confined soft templating route is developed. The gas permeance results indicate that the OMC hollow fiber membranes exhibit Knudsen diffusion behavior confirming their good quality.

Review on the preparation of carbon membranes derived from phenolic resins for gas separation: From petrochemical precursors to bioresources

“…Since the purpose of these membranes is gas separation, achieving high permeation rates would imply that the selective layer, which has molecular sieving properties, should be as thin as possible, a feature that can be addressed by investing effort in the preparation of the appropriate resin solution and coating method of the support.

Ordered mesoporous carbon film as an effective solid-phase microextraction coating for determination of benzene series from aqueous media

“…This method makes it possible to prepare continuous and smooth OMC film with different morphologies by finely controlling the self-assembly of the phenolic resin and block copolymer [31]. Currently, self-standing OMC films [32] and supported OMC films on different substrates like anodic alumina [33] and porous ceramic tube [34] have been successfully prepared, which indicate the possibility to prepare organic additive-free OMC film as SPME coating through a facile one-step route.…”

Synthesis of Helical Phenolic Resin Bundles through a Sol-Gel Transcription Method

“…Phenolic resins are widely used as industrial materials because of their thermostability, mechanical stability and acid resistance. In recent years, ordered mesoporous phenolic resins have attracted much attention because they can act as a promising carbon source to fabricate ordered mesoporous carbons [13,14,15]. The organic–organic organization of the phenolic resin precursor with the structure-directing agent—generally triblock copolymers—determined the morphology and pore architecture of the mesoporous phenolic resins [13].…”
