Designing Highly Photoactive Hybrid Aerogels for In-Flow Photocatalytic Contaminant Removal Using Silica-Coated Bacterial Nanocellulose Supports

ACS Applied Materials & Interfaces, Journal Year: 2023, Volume and Issue: 15(19), P. 23146 - 23159

Published: May 8, 2023

This study explores the use of silica-coated bacterial nanocellulose (BC) scaffolds with bulk macroscopic yet nanometric internal pores/structures as functional supports for high surface area titania aerogel photocatalysts to design flexible, self-standing, porous, and recyclable BC@SiO2–TiO2 hybrid organic–inorganic membranes effective in-flow photo-assisted removal organic pollutants. The aerogels were prepared by sequential sol–gel deposition SiO2 layer over BC, followed coating resulting BC@SiO2 a porous overlayer using epoxide-driven gelation, hydrothermal crystallization, subsequent supercritical drying. silica interlayer between biopolymer scaffold photocatalyst was found greatly influence structure composition, particularly TiO2 loading, membranes, allowing development photochemically stable materials increased area/pore volume higher photocatalytic activity. optimized showed up 12 times faster methylene blue dye from aqueous solution in comparison bare BC/TiO2 outperformed most supported-titania reported earlier. Moreover, developed successfully employed remove sertraline drug, model emergent contaminant, solution, thus further demonstrating their potential water purification.

Evaluation of adsorption performance and mechanisms of a highly effective 3D boron-doped graphene composite for amitriptyline pharmaceutical removal

Journal of Environmental Management, Journal Year: 2023, Volume and Issue: 344, P. 118363 - 118363

Published: July 4, 2023

Three-dimensional heteroatom-doped graphene presents a state-of-the-art approach for effective remediation of pharmaceutical wastewater on account its distinguished adsorption and physicochemical attributes. Amitriptyline is an emerging tricyclic antidepressant pollutant posing severe risks to living habitats through water supply food chain. With ultra-large surface area plentiful chemical functional groups, oxide favorable adsorbent decontaminating polluted water. Herein, new boron-doped composite reinforced with carboxymethyl cellulose was successfully developed via solution-based synthesis. Characterization study revealed that the formed by sheets intertwined into porous network engrafted 13.37 at% boron. The has zero charge at pH 6 contained various groups favoring attachment amitriptyline. It also found mere 10 mg able achieve relatively high amitriptyline removal (89.31%) 50 ppm solution concentration 30 °C. attained equilibrium within 60 min across concentrations ranging from 300 ppm. kinetic were well correlated pseudo-second-order Langmuir models, respectively, portraying highest capacity 737.4 mg/g. Notably, predominant mechanism chemisorption assisted physisorption contributed outstanding saturated sufficiently regenerated using ethanol eluent. results highlighted impressive performance as-synthesized in treating amitriptyline-containing waste effluent.

Environmentally Benign Nanoparticles for the Photocatalytic Degradation of Pharmaceutical Drugs

Catalysts, Journal Year: 2023, Volume and Issue: 13(3), P. 511 - 511

Published: March 2, 2023

A rapid rise in industrialization has led to the release of pharmaceutical pollutants into water bodies, rendering inappropriate for consumption by humans and animals, challenging our efforts achieve clean sustainable development goal. These include antibiotics, anticancer drugs, antidepressants, etc., which are highly stable persistent water, addition being harmful life. At times, secondary pollutant that is formed after degradation more potent than parent drug. Conventional purification methods cannot completely remove these pollutants. Hence, efficient robust required degrade waste. Photocatalytic drugs deemed an effective method environmental remediation, along with recovery photocatalysts, important recycling use. Herein, we present synthesis nanoparticles (NPs) their application photocatalytic waste as a preferred treatment method. Additionally, green nanomaterials offers benefit avoiding pollution. The NPs employed using plant extracts offer number metabolites reducing agents or capping agents, well use microbes nanofactories tackle issue cleanliness respect Despite regulations concerning drug disposal, some underdeveloped countries do not enforce practice guidelines letter spirit. current work presenting promising expected contribute assurance strict policy compliance enforcement, resulting resolution health concerns hazardous disposal bodies.
