However, due to the non-biodegradable and toxic nature of azo dyes, it is imperative to degrade the toxic dye in the textile effluent in order to prevent it from penetrating the aquatic ecosystem and causing environmental pollution. For this purpose, binary photocatalysts of polyaniline—tin oxide (PAni-SnO₂) with different weight percent of SnO₂ were synthesized using template-free method. The chemical structures and oxidation states of the photocatalysts were confirmed by Fourier transform infrared (FTIR) and ultra-violet visible (UV–Vis) spectroscopies, respectively. The existence of SnO₂ was characterized by X-ray diffraction (XRD) analysis, while morphology of the photocatalysts was investigated by field emission scanning electron microsocopy (FESEM). Electrical conductivities of PAni-SnO₂ binary photocatalysts were measured by conductivity meter showing conductivity range of 6.55 × 10^–6–2.66 × 10^–3 S cm⁻¹. The photodegradation performance of PAni-SnO₂ binary phorocatalysts for toxic RB5 azo dye was in the range of 30.26–72.94% in which PAni-SnO₂(10%) demonstrates the highest photodegradation performance of 72.94%. This can be explained by its high surface area nanorods and nanotubes morphology that promotes electron conductivity (2.66 × 10^–3 S cm⁻¹) and for better RB5 adsorption. Also, its low band gap (1.98 eV) enabling easy excitation of electrons to form electron–hole pairs and low electron-pair recombination rate (low PL emission intensity of 7.29 × 10³ a.u.) are the other factors that contribute to its excellent photodegradation performance.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":737,"journal":{"name":"Polymer Bulletin","volume":"82 1","pages":"313 - 334"},"PeriodicalIF":3.1,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143184807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fabrication of the sensor films process involves a two-step procedure consisting of melt compounding and compression molding on a laboratory scale. Optimization of the materials composition of the sensor film revealed the optimal concentrations of 0.5 wt% of BCG and 1 wt% of PVOH in the TPU matrix. A visible transition from yellow-orange to green upon exposure to gaseous and liquid ammonia was attributed to the deprotonation of BCG by ammonia nitrogen atom. Furthermore, the sensor exhibited an efficient gas detection limit of 25 ppm and good reversibility for at least 10 exposure cycles. Additionally, the sensor exhibits outstanding selectivity in detecting ammonia over various basic solutions. This study also demonstrates the feasibility of using the proposed system for industrial-scale production as exemplified by the fabrication of filament by continuous extrusion process.
