“…Alginate-and chitosan-based hydrogels are some of the more widely studied bio-adsorbents for such application [153][154][155][156][157]. Indeed, as three-dimensional cross-linked polymer networks, hydrogels can absorb large amounts of water, increasing the possibilities and efficiency of interactions between the functional groups of the adsorbent and the targeted soluble substances.…”

“…For instance, chitosan beads modified with 3-aminopropyl triethoxysilane resulted in significant increase of the adsorption maximum capacity, from 317.23 mg/g to 433.77 mg/g of reactive blue 4 dye (as compared to untreated chitosan beads) [155]. Chitosan can also be paired with natural fibres, bringing together favourable mechanical properties and functional characteristics in order to improve overall performance of the adsorbent [156,157]. This is the case for the chitosan-based biocomposites film reinforced with water hyacinth fibres recently developed by Pisitsak et al [157].…”

This is the case for the chitosan-based biocomposites film reinforced with water hyacinth fibres recently developed by Pisitsak et al [157]. The addition of bio-fillers increased the adsorption capacity of Cu 2+ ions from 6.4 mg/g to 34.1 mg/g, while improving the tensile modulus of the film by 400%.…”

The review covers recent literature on the ocean as both a source of biotechnological tools and as a source of bio-inspired materials. The emphasis is on marine biomacromolecules namely hyaluronic acid, chitin and chitosan, peptides, collagen, enzymes, polysaccharides from algae, and secondary metabolites like mycosporines. Their specific biological, physicochemical and structural properties together with relevant applications in biocomposite materials have been included. Additionally, it refers to the marine organisms as source of inspiration for the design and development of sustainable and functional (bio)materials. Marine biological functions that mimic reef fish mucus, marine adhesives and structural colouration are explained.

“…The removal of Pb 2+ , Zn 2+ , and Ni 2+ , with water hyacinth fiber, was also reported [34]. Additionally, the cadmium ion, Cu 2+ , and chromium (VI) ion heavy metal removal with water hyacinth-based biochar, chitosan materials, and water hyacinth roots, respectively, were also tested and showed good removal efficiencies [35][36][37]. Moreover, recycling performance of the heavy metals after accumulation on water hyacinth was also studied [38].…”

The Cr-doped ZnO photocatalysts were synthesized through the chromium ion accumulations by water hyacinth (Eichhornia crassipes). In the preparation process, the plant tissues were immersed in different sample flasks containing chromium precursors for 1, 2, 4, 6, and 8 days. The plant tissue containing chromium ion was mixed with zinc precursor followed by calcinations. For simplicity, the prepared Cr-doped ZnO samples with the plant immersed for 1, 2, 4, 6, and 8 days were abbreviated as D1, D2, D4, D6, and D8, respectively. Moreover, pure ZnO was also prepared without the water hyacinth plant accumulated with chromium ion for comparison purposes. The powder sample characterizations were performed and evaluated in the degradation of methylene blue (MB). The Cr-doped ZnO sample (D1) degrades 80% of MB dye while the D2, D4, D6, D8, and pure ZnO samples degrade only 74, 76, 79, 73, and 25%, respectively. On the other hand, without the addition of catalysts (blank), there was no significant degradation of MB dye within 90 min irradiation. Therefore, the degradation performance of Cr-doped ZnO in the presence of optimum amount of chromium dopant and water hyacinth is highly improved than that of pure ZnO. The catalytic improvement may be as a result of reducing the photogenerated electron and hole recombination rates due to the presence of dopants. Moreover, the presence of the Eichhornia crassipes plant in the synthesis of Cr-doped ZnO could also prevent further aggregations and particle size growth and enhance the porosity after calcination.
