The presence of SnVSO in the heterovalent states of Sn<sup>4+</sup>/Sn<sup>2+</sup> and V<sup>5+</sup>/V<sup>4+</sup> facilitates the rapid transfer of the electrons.

Through the integration of TiO<sub>2</sub> nanoparticles within a PLA matrix, the membrane is used to degrade ethanol as a model volatile organic compound (VOC) under UV light. Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Analysis (EDX), and UV–vis spectrophotometry confirm the porous structure of the membrane, the even distribution of TiO<sub>2,</sub> and its effective band gap of 3.06 eV, respectively. Ethanol adsorption is best described by the Langmuir isotherm model, suggesting monolayer coverage on a homogeneous surface. Photocatalytic tests demonstrate that the membrane decomposes ethanol (6800 ppm) within 14 min under UV light, generating acetaldehyde, acetic acid, formaldehyde, and formic acid as intermediates, and ultimately producing CO<sub>2</sub> and water. Reusability tests indicate a decrease in decomposition time over successive cycles due to increased TiO<sub>2</sub> exposure from the gradual degradation of PLA.

In this work we investigate an electrode material benefitting of multiwalled carbon nanotubes (MWCNTs), few layer graphene (FLG), and gold nano-powder catalyst to improve the Li-O<sub>2</sub> battery performances in terms of energy efficiency, cycle life and stability. Morphological, structural, and electrochemical tests indicate that the composite electrode can actually boost the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER), and enhance the Li-O<sub>2</sub> process reversibility, with a capacity of 1000 mAh g<sup>−1</sup> over 70 cycles. On the other hand, the tests reveal the role of the gold in decreasing the polarization and increasing the cell life. Therefore, the results suggest the combination of carbons with various morphologies as a suitable architecture for hosting the Li-O<sub>2</sub> reaction products and allowing their reversible reaction.

There is growing evidence that piezocatalysts can perform challenging chemical conversions from organic transformations to water splitting. A key challenge to piezocatlaysis is mitigating the inherent high relative permittivity of a ferroelectric material. This high permittivity restricts the transfer of carriers required for a chemical reaction to occur and reduces the reaction rate. Here the concept of producing a co-catalyst system is taken to enhance carrier mobility increasing the observed reaction rate. The study highlights the importance of determining the sonochemical and piezocatalytic contributions to catalysis. The combination of a Pt metal co-catalyst with BaTiO<sub>3</sub> through a simple solid-state method led to a four fold increase in the rate of H<sub>2</sub> production compared to BaTiO<sub>3</sub> and sonochemical reactions in the absence of a catalyst. BaTiO<sub>3</sub>/Pt is found to exhibit stable piezocatalytic performance over 12 h. Where there is a deviation from steady-state water splitting, it is shown that this is due to mechanical removal of Pt rather than a phase change in the catalyst system. This work confirms the additive benefits of hybrid materials for improving piezocatalytic processes.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":null,"pages":null},"PeriodicalIF":7.1,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142266084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
