Novel Multiphase CO2 Photocatalysis System Using N-TiO2/CNCs and CO2 Nanobubble

International Journal of Technology
In this study, a novel CO2 photocatalysis system was developed by modifying TiO2 as a photocatalyst and introducing CO2 nanobubble to the system. TiO2 photocatalyst is modified by adding CNCs as support to increase the surface area and adding nitrogen

Release of TiO2 from paints containing pigment-TiO2 or nano-TiO2 by weathering

Environmental Science: Processes & Impacts, 2013
The release of nanomaterials from products and applications that are used by industry and consumers has only been studied to a very limited extent. The amount and the characteristics of the released particles determine the potential environmental exposure. In this work we investigated the release of Ti from paints containing pigment-TiO2 and nano-TiO2.

Electronic structure and enhanced visible light absorption of N, B-codoped TiO2

, 2012
We present the GGA+U calculations to investigate the electronic structure and visible light absorption of the N, B-codoped anatase TiO2. The NsBi (substitutional N, interstitial B) codoped TiO2 produces significant Ti 3d and N 2p mid-gap states when the ...
