A comparative study on the VOCs sensing behaviors of various ZnO nanostructures

The volatile organic compounds (VOCs) sensing layers were studied using ZnO nanomaterials with different morphologies including hierarchical nanostructure (ZnO-H), nanorods (ZnO-NRs), commercial nanoparticles (ZnOCNPs) and wet chemical synthesized nanoparticles (ZnO-HNPs). ZnO hierarchical structure was fabricated by an electrospinning technique followed by hydrothermal process.

Synthesis and characterization of hierarchical CEO2 spherical nanoparticles for photocatalytic degradation of methylene blue

The results show that the cerium oxide spherical nanoparticles built from primary nanoparticles with the average size of ~5 nm, exhibited dispersion and uniform size and shapes with their average particle diameter of ~50 nm in size. With such a good morphology, CeO2 material possessed good catalytic activity for the decomposition of methylene blue (MB), in which the material was synthesized at a hydrothermal temperature of 80 oC (CeO2-80) for the best MB decomposition performance.
