Robust Biobased Membrane: Self-Entangled Cellulose Nanofibrils–ZnO–Ag Composite with High Photocatalytic Performance for Efficient Dye-Contaminated Water Treatment

“…In practical applications, it is essential to establish strong bonding between the photocatalytic particles and the cellulose substrate to prevent the release of the particles in water and subsequent secondary pollution. Until now, the composite has usually been prepared by direct synthesis of metal NPs on the cellulose substrate − and utilization of post-treatments such as microwave and hydrothermal treatment to precisely control the size and shape of the nanoparticles. ,, However, these post-treatments, involving a high temperature and pressure in the presence of water, can disrupt the hydrogen bonding between cellulose fibers and weaken the structure of the composite. The strength of cellulose-based materials, such as paper and membranes, largely relies on the hydrogen bonding between the cellulose fibers.…”

Cu and Ni dual-doped ZnO nanostructures templated by cellulose nanofibrils for the boosted visible-light photocatalytic degradation of wastewater pollutants

“…The advanced oxidation process (AOP) using photocatalysts is one of the most important technologies since it degrades many complex organic compounds. 7,8 During this process, the hydroxyl radicals ( • OH) generated in situ by the photocatalyst particles while harvesting the light energy initiate a sequence of interfacial and bulk reactions, which lead to the degradation of organic molecules eventually. 9,10 Morphology-rich zinc oxide (ZnO) is emerging as a promising photocatalyst due to its unique features like nontoxicity, biocompatibility and low cost.…”

A robust and efficient lipase based nanobiocatalyst for phenothiazinyl-ethanol resolution

“…4,5 Meanwhile, for nanoparticles, it is difficult to disperse them in solution and further to recover and to reuse them; nanofibers can be easily separated and reused or applied in continuous flow processes. [6][7][8] Biopolymer nanofibers are intensively studied for biomedical applications such as tissue engineering for implants, wound dressings, and drug delivery, and also as supports for enzyme immobilization. Due to their large scale availability and low cost, biodegradability and biocompatibility, the use of biobased polymers has gained considerable interest for the development of sustainable and green processes.…”
