The TiO<sub>2</sub>-FeBTC-BiPOM (6 %) nanocomposites doped with 400 μg/mL CQDs exhibited improved performance with lower charge transfer resistance. As a result, this electrode was used to fabricate a novel natural dye (chlorophyll, anthocyanin and cocktail mixture)-based DSSCs.The cocktail based mixture showed higher power conversion efficiency of 1.92 % compared to spinach based DSSCs (0.98 %) and purple cabbage (0.89 %) under 100 mW/cm<sup>2</sup> light illumination with 30 ms of electron lifetime, which is three times and four times more than spinach and cabbage based DSSCs respectively. In comparison to synthetic DSSCs, the efficiency of the natural dyes was still lower than N3 dyes. However, considering practical requirements of DSSCs, the natural dye-based devices satisfy most of the criteria such as affordability, ease of extraction, multiple wavelengths that can be absorbed with large coefficient, non-toxicity, and wide availability.</div></div>","PeriodicalId":100233,"journal":{"name":"Chemistry of Inorganic Materials","volume":"5 ","pages":"Article 100087"},"PeriodicalIF":0.0,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143134903","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}

The comparison of the results obtained with the software HighScore Plus with those of the method developed in our research group by Cano-Casanova et al., based on the deconvolution of the XRD peaks of anatase, brookite, and rutile, has shown that the results of both methods are very similar, and the HighScore Plus software can definitively be used for an easy determination of the amorphous phase content in titanium dioxide, even for materials with the three crystalline phases, rather overlapping peaks, and/or with a high amorphous phase content, which cannot be easily characterized by the method by Cano-Casanova el al. Thus, amorphous phase contents in the 5-51 % range are obtained with the HighScore Plus method, in contrast with 8–47 % for the previously developed methodology.

Its ability to easily transition between the Ce³⁺ and Ce⁴⁺ oxidation states, which promotes redox reactions, accounts for its exceptional catalytic activity. Additionally, CeO₂ has remarkable antioxidant properties due to its ability to reduce oxidative stress and scavenge reactive oxygen species (ROS).
