Although considerable effort has gone into the development of methods that accurately predict the optical properties of perovskite materials based on structure, the reverse—predicting composition from optical data—is far less explored. In this study, high-throughput approaches were employed to synthesize and spectroscopically analyze a wide array of perovskites composed of mono-halide, di-halide, and tri-halides with a general formula, MA<sub>x</sub>Cs<sub>1−x</sub>Pb(Cl<sub>x</sub>Br<sub>y</sub>I<sub>1−x−y</sub>)<sub>3</sub>. The spectroscopic data were used to train an artificial neural network (ANN)-based chemical space-property predictor model designed to work with multiple responses and multiple predictors. The model predicted the chemical composition of perovskites from terahertz (THz) Raman spectroscopic data with approximately 85% accuracy. When the dataset also incorporated UV-visible spectroscopic data, the accuracy increased to nearly 92%. This study opens the possibility of real-time monitoring and defect detection, degradation analysis, and streamlined material selection and optimization of perovskite materials in industrial production.","PeriodicalId":268,"journal":{"name":"Chem","volume":"38 1","pages":""},"PeriodicalIF":23.5,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142783066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such improvements can address supply chain challenges for cobalt, a critical element. Herein, we disclose a simple method for separating Co/Ni by second coordination-sphere molecular recognition. Selective cobalt precipitation is achieved using carbonate ions in an ammonia solution due to the outer-sphere, hydrogen bonding interactions between [Co(NH<sub>3</sub>)<sub>6</sub>]<sup>3+</sup> and CO<sub>3</sub><sup>2−</sup>, evaluated with density functional theory calculations. We demonstrate this method on mixtures of Co/Ni chlorides comprising a 10-fold excess of Ni and provide comparisons with ore-processing systems. High purities (99.4(3)% Co; 98.2(4)% Ni) and recoveries (77(8)% Co; ∼100% Ni) were observed for both Co- and Ni-enriched products using optimized conditions. This method is potentially economically competitive based on initial techno-economic analysis (TEA) and life-cycle assessment (LCA) that also illustrate advantages in terms of sustainability.","PeriodicalId":268,"journal":{"name":"Chem","volume":"9 1","pages":""},"PeriodicalIF":23.5,"publicationDate":"2024-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142760253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electro-solar approaches, such as electrochemical (EC), photochemical (PC), and photoelectrochemical (PEC) methods, are promising for CO2RR due to their efficiency and mild operating conditions. The process of converting CO<sub>2</sub> into valuable products involves multiple steps and requires a deep understanding of reaction mechanisms and product selectivity. <em>In situ</em> and <em>operando</em> spectroscopic techniques are essential for elucidating these mechanisms. This review focuses on advanced <em>in situ</em> spectroscopic methods, such as X-ray absorption spectroscopy (XAS), infrared (IR) spectroscopy, Raman spectroscopy, and electron paramagnetic resonance (EPR) spectroscopy, which provide insights into CO<sub>2</sub> adsorption, activation, and electron-proton transfer, leading to intermediate radical formation.

This strategy and its more modern variants are all based on an initial single-electron transfer event converting the arene into the corresponding radical anion for either protonation or hydrogen-atom transfer. Herein, we demonstrate an umpolung approach where the aromatic is first protonated to its corresponding carbocation and then reduced using the Lewis acid-base complex Et<sub>3</sub>N−BH<sub>3</sub>. This strategy requires aromatic photoexcitation so that protonation is favored by charge-transfer and driven by excited-state antiaromaticity relief. This means that aromatic excited-state basicity rather than ground-state redox potential needs to be considered when approaching reaction development.
