On one hand, a thorough review of methods for synthesizing nanostructured TiO₂ is presented. Using these methods, and different post-synthesis heat-treatment conditions, close to thirty TiO₂ materials have been prepared, and their porous texture and crystalline and amorphous structure have been characterized. In this large number of samples, the porous texture characterization has revealed a high contribution of mesoporosity in a large number of the synthesized materials, being in many materials around 60–70 %. Moreover, different percentages of crystalline phases, anatase, brookite, rutile, and amorphous titania are developed depending on the TiO₂ preparation conditions. These fractions have been determined from X-ray diffraction data using the <em>“simple”</em> characterization method reported by Cano-Casanova et al., inspired by Jensen et al., and Bellardita et al., also exploring its limitations. This analysis has allowed assessing a linear relationship between porosity, particularly between the surface area, and the amorphous phase content in titanium dioxide. A relationship had been previously suggested in the literature, but never correlated in such a way. In summary, the present study constitutes a tool to help other researchers select the most suitable method for synthesizing nanostructured TiO₂ materials with target properties and, also, to characterize them, and have a very easy and straightforward estimation of TiO₂ amorphous phase content after the determination of their surface areas.</p></div>","PeriodicalId":100233,"journal":{"name":"Chemistry of Inorganic Materials","volume":"3 ","pages":"Article 100059"},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949746924000272/pdfft?md5=80400212962f236ef84e67ddcdcc5a3d&pid=1-s2.0-S2949746924000272-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141481354","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}

This marks the first utilization of the FAP-IL chemical additive, specifically 1-hexyl-2,3-dimethyl-imidazolium tris(pentafluoroethyl) trifluorophosphate, in the preparation of the PSK layer. This novel addition not only enhances the hydrophobic characteristics of the PSK layer, safeguarding it against moisture-induced deterioration and preserving its α-phase, but also ensures defect passivation via hydrogen bonds formed between N and F atoms in the IL with the organic cation of the PSK, thus preventing the migration of organic cations to grain boundaries. Furthermore, the lone pairs on neutral nitrogens are easily donated to under-coordinated Pb²⁺ cations, resulting in the stabilization of the PSK crystal structure. This configuration is further augmented by the attributes of carbon paste such as a high electrical conductivity (∼0.75 ​S ​cm⁻¹) and substantial hole density exceeding 10¹⁶/cm³, resulting in impressive performance metrics, with a power conversion efficiency (PCE) of ∼7.5% and prolonged stability in air.
