Ferroelectric BaTiO ₃/Pr ₂O ₃ heterojunction harvesting room-temperature cold–hot alternation energy for efficiently pyrocatalytic dye decomposition

Journal of Advanced Ceramics, Год журнала: 2023, Номер 13(1), С. 44 - 52

Опубликована: Ноя. 27, 2023

The strong pyrocatalytic dye decomposition of the BaTiO₃/Pr₂O₃ heterojunction catalyst under cold-hot alternation conditions has been demonstrated in this work. For pure BaTiO₃ nanofibers, ~54% rhodamine B (RhB) is decomposed 29–57 ℃ alternation. With loading content Pr₂O₃ increases from 0 to 4 wt%, ratio RhB solution increased first and then decreases, eventually achieving a maximum 91% at 3.0 wt%. enhanced performance after can be attributed internal electric field heterojunction, which effectively separates positive negative charges. strongly makes it hopeful for application wastewater treatment through harvesting environmental temperature thermal energy future.

Ferroelectrics as emerging and attractive catalysts have shown tremendous potential for applications including wastewater treatment, hydrogen production, nitrogen fixation, organic synthesis, etc. In this study, we demonstrate that molecular ferroelectric crystal TMCM-CdCl3 (TMCM = trimethylchloromethylammonium) with multiaxial ferroelectricity superior piezoelectricity has an effective catalytic activity on the direct construction of pharmacologically important substituted quinoline derivatives via one-pot [3 + 2 1] annulation anilines terminal alkynes by using N,N-dimethylformamide (DMF) carbon source. The recrystallized crystals from DMF remain well piezoelectricity. Upon ultrasonic condition, periodic changes in polarization contribute to release free charges surface domains nano size, which then quickly interacts substrates solution trigger pivotal redox process. Our work advances a route not only providing valuable direction ferroelectrics but also further enriching executable range catalysis. Molecular possess switchable spontaneous polarization. Here, authors show demonstrates evident effects synthesis quinolines.
