2023年11月23日 · In this work, a series of materials, such as SnO2, Sn3O4 and Sn3O4/SnO2 heterostructures, with different phase ratios were prepared using hydrothermal synthesis. The materials were characterized using X-ray diffraction (XRD), Raman and diffuse reflectance spectroscopy (DRS), high resolution transmission electron microscopy (HRTEM), nitrogen ...

2020年6月1日 · In this study, we proposed that the coordination effect between a metal ion and an exposed fluorine atom on the surface of PVDF can be used to assemble a layer of photocatalytic metal oxide nanostructures on the PVDF film surface. Using Sn 3 O 4 as a model oxide, a Sn 3 O 4 /PVDF hybrid nanostructured photocatalyst was successfully synthesized.

International Journal of Minerals, Metallurgy and Materials (IJMMM, ISSN 1674-4799, CN 11-5787/TF, monthly, started in 1994, formerly known as Journal of University of Science and Technology Beijing) is an international journal devoted to publishing original research articles (and occasional invited reviews) on all aspects of minerals processing, physical metallurgy, process metallurgy, and ...

A photocatalytic degradation test showed that the highest efficiency degradation of rhodamine B (RhB) was obtained using type II SnO/Sn 3 O 4 heterostructure semiconductors with a degradation rate constant of 2.3 × 10 −3 min −1.

2020年12月15日 · Sn 3 O 4 is a promising, low-cost, nontoxic catalyst with suitable bandgap structure for visible-light hydrogen evolution reaction (HER). The micro-structural modifications leading to more efficient charge separation is essential for …

2023年7月1日 · Raman studies found the presence of small amounts of Sn3 O 4 or Sn 2 O 3 phases in the nanoparticles. The presence of oxygen vacancies in the nanoparticles was established by XPS. Their density increase accompanies by the …

Sn-based electrocatalysts have recently been applied for CO2 reduction to generate fuels. Here, tin oxide crossed architectures (SnO) and petal-like Sn3O4 semiconductors were synthesized using...
