Green nanoparticles can be synthesized in an environment-friendly way while retaining all the advantages of traditional nanoparticles and more. In this study, a novel saponin-capped copper oxide nanoparticle system was synthesized. Saponin, a secondary metabolite in numerous plants, offers eco-friendly and sustainable alternatives for a wide range of biomedical applications. Saponin was isolated from soapnut in an aqueous medium and a standard protocol for green synthesis of saponin-capped copper oxide nanoparticles was optimized. The synthesized nanoparticles were characterized using various techniques and tested for their ability to photocatalyze the degradation of methylene blue, a toxic synthetic dye. X-ray diffraction confirmed the formation of CuO in both samples and UV–Vis and Fourier transform infrared spectroscopies confirmed the presence of saponin in the green-synthesised samples. Scanning electron microscopic analysis of the samples revealed the formation of bigger nano-spheroids for bare CuO (average diameter 244.1 ± 36.3 nm) and smaller irregular clusters for saponin-capped CuO (average length 147.1 ± 41.6 nm). Both these nanostructures were formed by the accumulation of smaller nanoparticles (<30 nm). Through efficient photocatalytic degradation of methylene blue in water, nanoparticles extended a simple and eco-friendly route for environmental remediation and water purification. Saponin-capped CuO nanoparticles catalyzed 86.32 % degradation of the dye, significantly higher than that degraded by bare copper oxide nanoparticles (13.14 %). The results signified the enhanced potential of the saponin-capped nanoparticles compared to the bare CuO ones as nano-photocatalyst.</div></div>","PeriodicalId":101197,"journal":{"name":"Sustainable Chemistry One World","volume":"6 ","pages":"Article 100054"},"PeriodicalIF":0.0,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143807602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among various conversion technologies, pyrolysis stands out as one of the most efficient, converting biomass into solid, liquid, and gaseous products with high potential for energy applications. This study provides a comprehensive analysis of different pyrolysis methods in the context of macroalgae processing. It explores how operating parameters, such as temperature, heating rate, and residence time, influence the yield and quality of pyrolysis products, biochar, bio-oil and gas. The findings demonstrate that slow pyrolysis, conducted at lower temperatures and longer residence times, yields higher biochar, while fast pyrolysis, with higher temperatures and shorter residence times maximizes bio-oil production. Intermediate pyrolysis balances biochar and bio-oil outputs, whereas flash pyrolysis favors biofuel production with faster heating rates. Catalytic fast pyrolysis demonstrates strong potential for producing high-value hydrocarbons. Microwave-assisted pyrolysis of macroalgae produces significant syngas and bio-oil with high heating values and lower oxygen content. Additionally, co-pyrolysis with suitable co-feedstocks further enhances bio-oil properties. This study highlights the potential of macroalgae as a renewable resource, emphasizing the versatile applications of pyrolysis products. Harvesting macroalgae during the peak growth, optimizing pyrolysis parameters, integrating complementary techniques, and using efficient catalysts can significantly enhance conversion and yields.

A modified adsorbent, nitric acid-functionalized rice husk (NT-RH) was synthesized and characterized using SEM-EDX, PXRD, and FTIR techniques to assess its structural properties. The NT-RH exhibited a porous, macro-structured network that enhanced its adsorption capacity. Batch experiments examined key Mn(II) removal variables, including adsorbent dosage, temperature, contact time, and pH. The results demonstrated a maximum removal efficiency of Mn(II) of 94.96 % under optimal conditions, which included a manganese concentration of 50 ppm, an adsorbent mass of 0.6 g, a temperature of 25°C, a pH of 7, and a contact time of 60 minutes. The adsorption process was spontaneous and exothermic, with kinetics described by a pseudo-second-order model and isotherms best represented by the Freundlich model. Therefore, this research highlights the potential of rice husk as a sustainable material for removing Mn(II), effectively addressing the dual challenges of agricultural waste management and water purification.
