Fabrics comprised of porous fibres could provide effective passive protection against chemical and biological (CB) threats whilst maintaining high air permeability (breathability). Here, we fabricate hierarchically porous fibres consisting of regenerated silk fibroin (RSF) and activated-carbon (AC) prepared through two fibre spinning techniques in combination with ice-templating—namely cryogenic solution blow spinning (Cryo-SBS) and cryogenic wet-spinning (Cryo-WS). The Cryo-WS RSF fibres had exceptionally small macropores (as low as 0.1 µm) and high specific surface areas (SSAs) of up to 79 m2·g−1. The incorporation of AC could further increase the SSA to 210 m2·g−1 (25 wt.% loading) whilst also increasing adsorption capacity for volatile organic compounds (VOCs).

Organic contaminated wastes water from petrochemical industries can be removed by adsorbent and photocatalyst. In this work, the degradation rate of phenol have been studied at different ratios of activated carbon/NaA zeolite composite materials coated with TiO2 photocatalyst which are easily to be fabricated into tubular shape by extrusion method. In addition, the foam-inserted composite can be floated on the surface of waste water for the higher phocatalyst activity. While the composite is the low cost adsorbent with high absorption and high ion exchange properties. In order to optimize the efficiency of material, the various ratios of activated carbon/NaA zeolite (3:1, 1:1 and 1:3) and amount of coated TiO2 on the specimen’s surface was studied by UV/Vis spectrophotometer which related to phenol concentration. Moreover the various amount of phenolic resins (10, 20, 30, 40 and 50 wt%) at different reduction firing temperatures (600 and 650 °C) with soaking time of 1, 2 and 3 hours affected to the compressive strength of samples. For the characterization, XRD is used to characterize the phase and SEM is used to provide the morphology of the prepared composite materials.
