Alkaline earth stannates applied in photocatalysis: prospection and review of literature

Abstract: The ABO 3 mixed oxide class known for its perovskite-like structure has aroused great scientific and technological interest in recent decades, due to its optical, magnetic and conductive properties. The objective of this work was to search the articles and patent databases for papers that relate the activity of the alkaline earth metal stannates -BaSnO 3 , CaSnO 3 and SrSnO 3 as photocatalysts for environmental application. The databases researched were the Web of Science, Scopus and Scielo for articles and US… Show more

“…Furthermore, in works on photocatalysis with the participation of MSnO 3 , the transformation mechanisms were rarely analyzed, and accurate information on the spectral characteristics of radiation sources is often lacking. 8 The last two cited works in this context are more informative and can serve as a convenient example for comparison with the results of our study.…”

“…However, to date, a relatively low number of works have been devoted to the photocatalytic activity of MSnO 3 (M = Ba, Sr) as follows from a recently published review. 8 The stannates have been tested both in the processes of water decomposition (generation of hydrogen and oxygen) and in the processes of photocatalytic decomposition of dyes (potential environmental pollutants). 9–11…”

“…The perovskite structural ASnO 3 possess wide optical bandgaps, exhibiting a broad transparent visible photovoltaic effective range and outstanding electrical properties. Very recently, the experimentally synthesized BaSnO 3 perovskite was found to exhibit a high carrier mobility of 320 cm 2 ·V –1 ·S –1 at room temperature, which was expected to be an excellent TCO material . In addition, the luminescent properties of ASnO 3 proved to have potential applications in environmental prevention and remediation processes. For instance, SrSnO 3 showed high activities in photocatalytic water splitting due to the distorted SnO 6 octahedral connection and strong electron–lattice interaction, which could be designed as a promising material for developing new photocatalytic systems …”
