Iani, Isabela M. [UNESP]; Teodoro, Vinícius; Marana, Naiara L. [UNESP]; Coleto, Ubirajara; Sambrano, Julio R. [UNESP]; Simões, Alexandre Z. [UNESP]Made available in DSpace on 2021-06-25T11:05:38Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-02-01; Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Na2Ti3O7/H2Ti3O7 heterojunction nanotubes were obtained through the microwave-assisted hydrothermal method (MAH) with different band gap energy engineering. This study aimed to synthesize sodium titanate nanotubes and evaluate the inf...
Correlation of photocatalytic activity and defects generated in Ca2+-based hete...
Coleto, Ubirajara [UNESP]; Amoresi, Rafael A. C. [UNESP]; Pereira, Chrystopher A. M. [UNESP]; Schmidt, Bruna W. [UNESP]; Iani, Isabela M. [UNESP]Made available in DSpace on 2021-06-25T11:11:23Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-11-01; Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); In this work a new semiconductor based on calcium heterojunction (CaO/CaTiO3) was evaluated to the optical properties correlated to crystalline lattice defects. The heterojunctions of the semiconductor were prepared by the sol–gel route and ...
An approach for photodegradation mechanism at TiO2/SrTiO3 interface
Coleto, Ubirajara [UNESP]; Amoresi, Rafael A. C. [UNESP]; Teodoro, Vinícius; Iani, Isabela M. [UNESP]; Longo, Elson; Zaghete, Maria A. [UNESP]Made available in DSpace on 2019-10-06T15:23:22Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-12-01; TiO2/SrTiO3 heterojunction powders were obtained and characterized, and their photocatalytic potential was evaluated. The formation of the solid–solid interface was evidenced by secondary-phase formation in the interface region, which was observed using transmission electron microscopy. The photocatalyt...
