Abstract:

AbstractCO2 adsorption is a promising strategy to reduce costs and energy use for CO2 separation. In this study, we developed CO2 adsorbents based on lightweight and flexible cellulose nanofiber aerogels with monolithic structures prepared via freeze-casting, and cellulose acetate or acetylated cellulose nanocrystals (a-CNCs) were introduced into the aerogels as functional materials using an impregnation method to provide CO2 affinity. The microstructure of the adsorbent was examined using scanning electron microscopy, and compression tests were performed to analyze the mechanical properties o

Abstract:

The application of the immobilisation method – which consists of immobilising modified sawdust in a carrier, a chitosan gel – enabled the development of a new sorbent. By combining waste products from chitin and sawdust, the properties of both adsorbents were utilised. This paper evaluated the adsorption efficiency of four dyes – Reactive Yellow 84, Reactive Black 8, Basic Violet 10 and Basic Green 4 – on four adsorbents – chitin flakes, chitosan flakes, chitosan beads and sawdust immobilised in chitosan beads. The latter adsorbent showed good adsorption properties for both anionic and cationi

Abstract:

As a potential magnetic super adsorbent in wastewater treatment, Fe3O4 has been researched intensively up to date. However, its key problem of poor comprehensive magnetic properties is still challenging. In this work, an effective solution to this problem has been developed by a one-step carbothermal synthesis of Fe3O4 crystals, which are merited with pure-stoichiometry (FeO-phase free), high crystallinity, small-size (~10 nm), strong magnetism and sensitive magnetic response. The unveiled saturation magnetization of Fe3O4 nanoparticles reaches as high as 90.32 emu·g−1, and the fastest magneti
