The performance of Ag/TiO₂ nanocomposite was examined by degradation of methylene blue (MB) dye as a model of organic pollutant. The dye degradation using the Ag/TiO₂ nanocomposite containing 45 mM of Ag revealed the high MB degradation, which is 85.77 % after 30 min under dark condition. Furthermore, complete degradation of 96.76 % was achieved after 2 h under visible light irradiation. In contrast, bare TiO₂ only achieved 41.45 % after 30 min dark and 2 h visible light irradiation. This increase in degradation efficiency can be attributed to the adsorption process and the enhanced light absorption resulting from the localized surface plasmon resonance (LSPR) effect of Ag. Therefore, the green-synthesized Ag/TiO₂ nanocomposite has great potential as an integrated adsorbent photocatalyst materials for remediating organic pollutants in dye effluents.</p></div>","PeriodicalId":296,"journal":{"name":"Current Research in Green and Sustainable Chemistry","volume":"8 ","pages":"Article 100394"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666086523000401/pdfft?md5=65925a597a5dce401eb2905ca3eece75&pid=1-s2.0-S2666086523000401-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139071634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lignin-based polyol and furfuryl alcohol were used to produce furan-lignin foams, which are free of formaldehyde and ozone damaging substances. Seven different furan-lignin foams were produced by substituting the toxic formaldehyde with a more eco-friendly glyoxal as a hardener while using diethyl ether and bentonite as blowing agent and filler respectively. Effects of these reagents on the quality of foams produced were assessed by varying their contents in the formulations. The properties of the produced bio-based foams such as compressive resistance, water absorption capacity, density and moisture content were evaluated. Further product characterizations: elemental composition, thermo-gravimetric analysis, Fourier transforms infrared spectroscopy and Scanning electron microscopy were carried out on the foams. The reaction leading to foam production was spontaneous at room temperature with an acid catalyst. Results showed that the concentrations of the blowing agent, hardener and filler, all had effects on the quality of the bio-based foams produced. Scanning electron microscopy results showed that the foams possessed closed cell morphologies, a rigid foam characteristic for good thermal and acoustic performance but modest water absorption, with cell widths of 10–200 μm, having high densities and strong compressive strengths as inherent characteristics.

In response, eco-friendly adsorbents derived from agricultural waste, such as Fava Bean Peels (R–FBP), have been investigated as potential materials for the removal of such pollutants. In this study, R–FBP and their corresponding physical and chemically activated carbon (P-RFB-AC and C-FBP-AC) were synthesized using H₃PO₄ acid and characterized using FT-IR, and SEM analyses. An optimization process was conducted to determine the optimum conditions for achieving high Methyl Orange (M. Orange) removal efficiencies using the prepared materials, namely R–FBP, P-RFB-AC, and C-FBP-AC. The adsorption mechanism was examined by analyzing the isotherm and kinetics. The results revealed that the physical raw-activated carbon exhibited the highest removal efficiency of 96.8% compared to other materials. This outcome was achieved through the use of ANN combined with Moth Search Algorithm (MSA), which was found to be the most effective model for achieving the highest M. Orange removal efficiency from Physical raw fava bean activated carbon. Under parameters of 1000 mg/l M. Orange concentration, 2 g/l dose, 15 min contact time, and 120 rpm shaking, the best experimental and predicted removal efficiencies for physical-activated carbon fava bean rind were 96.8 RE%, 96.01 indicated RSM RE%, and 95.75 predicted ANN RE%. The highest experimental and predicted removal efficiencies for the H₃PO₄ chemical activated carbon fava bean peel were 94%RE. This study aimed to develop an economical solution for treating industrial wastewater contaminated with anionic M.

Additionally, this research delves into the intricate relationship between pH levels and fabric cationisation, exploring their combined impact on the functional properties of naturally dyed cotton samples. Preceding the dyeing process, the cotton fabric underwent cationisation through the application of 3-chloro-2-hydroxypropyl trimethyl ammonium chloride (CHPTAC) at varying percentages. Subsequently, the fabric was dyed with tea liquor at different concentrations and pH levels. The ensuing investigation encompassed an assessment of color fastness and colorimetric attributes (CIELab, CIELch, ΔE, and K/S) of the dyed cotton fabrics. Furthermore, FTIR analysis was employed to augment our understanding of the dyeing process, while UV-Vis spectroscopy facilitated the quantification of exhaustion and fixation percentages. The results indicate that the highest exhaustion percentage of 88.6% was achieved at pH 13 for cationised fabric with a cationiser concentration of 55 g/L. In comparison, the non-cationised fabric exhibited an exhaustion percentage of 0.75%, while the mordanted (KAI(SO₄)₂.12H₂O) fabric showed 3.6%. Furthermore, the cationised fabric displayed excellent colour fastness to washing, rubbing, and perspiration (rated 4–5) compared to the non-cationised fabric. The stronger interaction calculated with density functional theory (DFT) between theaflavins, one of the primary colour components of tea dye, and cationised cellulose monomers explains the enhanced washing and rubbing fastness observed.

In this regard, the financial sector needs sound approaches to assess the sustainability of investments. With this paper, we show an approach to assess the environmental performance of investments through key performance indicators calculated based on life cycle assessment. The approach is applied for the assessment of a fictitious investment aimed at financing bio-based and biodegradable plastic mulch films. The performance is assessed by comparing changes induced by the investment, compared with what would have happened without the investment (i.e., using fossil-based plastic mulch films). The application of the approach shows that the investment could be in general favourable from an environmental point of view, in particular for the promotion of a more circular and low-carbon economy. The approach could be easily adapted to reflect the specificities of a wide range of investments.
