Efficient and Facile Synthetic Route of MoO:MoS Hybrid Thin Layer via Oxidative Reaction of MoS Nanoflakes.

In the present study, MoO:MoS hybrid thin layers have been synthesized through partial oxidation of MoS. We have demonstrated that the reaction requires darkness conditions to decrease the oxidation rate, thus obtaining the hybrid, MoO:MoS. A simple liquid-phase exfoliation (LPE) is carried out to achieve homogenous MoS nanoflakes and high reproducibility of the results after MoS oxidation.

Dye decomposition and air de-pollution performance of TiO/SiO and N-TiO/SiO photocatalysts coated on Portland cement mortar substates.

In this study, the newly synthesized TiO and N doped TiO clusters were added to silica sol to synthesize N-TiO/SiO composites via the sol-gel method. Afterwards, the prepared sols were applied by brushing on portland cement. Doping with nitrogen significantly increased the absorption of TiO towards the visible region, thus, increasing the photocatalytic activity.
