Insight Into the Origins of N2O Byproduct on Confinement Structure TiO2/MnSm Catalyst Through Sulfation Pre‐Treatment for Low‐Temperature NH3‐SCR Reaction

EcoEnergy, EarlyView.
Sulfation of TiO2 with tubular architecture assembly nanosheets cooperated with Sm modification endowed the TiO2–SO42−/MnSm catalyst with excellent low‐temperature NH3‐SCR activity, high N2 selectivity, and well H2O‐resistance. It clarifies how the Sm modification and sulfation adjusts the distribution of acid sites and modulates the activation of NH3 ...

The cytotoxic targets of anatase or rutile + anatase nanoparticles depend on the plant species

Biologia plantarum, 2017
The potential toxicity of nanoparticles (NPs) is under debate. Information about TiO2 NPs phytotoxicity is still limited partly due to the different TiO2 NP forms that may be found in the environment. The present work investigated the impact of different TiO2 NPs forms (rutile and anatase) on germination, growth, cell cycle profile, ploidy level, and ...

X-ray Anomalous Scattering of Diluted Magnetic Oxide Semiconductors: Possible Evidence of Lattice Deformation for High Temperature Ferromagnetism

, 2007
We have examined whether the Co ions crystallographically substitute on the Ti sites in rutile and anatase Ti_{1-x}$Co$_{x}$O$_{2-delta}$ thin films that exhibit room-temperature ferromagnetism.
