Hydroxylated TiO2-induced high-density Ni clusters for breaking the activity-selectivity trade-off of CO2 hydrogenationThe reverse water gas shift reaction can be considered as a promising route to mitigate global warming by converting CO 2 into syngas in a large scale, while it is still ...
Formation and structure of the Ni-cluster/TiO2catalyst By using the commercial anatase TiO2as a precursor (denoted by TiO2-Ref1, Fig.1a), hydroxylated H2Ti3O7was obtained as support for the Ni/TiO2catalyst37,38. The detailed synthesis process and the corresponding catalyst structure evolution wer...
The adsorption and dissociation of NH3 on the clean and hydroxylated TiO2 rutile (110) surfaces have been investigated by the first-principles calculations. The monodentate adsorbates such as H3N Ti(a), H2N Ti(a), N Ti(a), H2N O(a), HN O(a), N O(a) and H O(a), as well as ...

The amorphous TiO2 derived from hydroxylation has become an effective approach for the enhancement of photocatalytic activity of TiO2 since a kind of special black TiO2 was prepared by engineering disordered layers on TiO2 nanocrystals via hydrogenation. In this contribution, we prepared totally amorphous...

Fullerene-C60 derivatives prevent UV-irradiation/ TiO2-induced cytotoxicity on keratinocytes and 3D-skin tissues through antioxidant actions. Microcorpuscular titanium dioxide (TiO2), a useful sunscreen agent, photocatalyzes generation of reactive oxygen species (ROS). We assessed protective effe... Shinya...

Enhanced photocatalytic activity of silver metallized TiO2 particles in the degradation of an azo dye methyl orange: Characterization and activity at diffe... The photocatalytic activity of silver deposited Degussa P25 titanium dioxide (Ag-DP25) in the photodegradation of methyl orange (MO) was inves...
Herein, a facile and controllable strategy to synthesize self﹉ydroxylated TiO2 nanocrystals with promoted photocatalytic activity in hydrogen evolution is demonstrated. Various colors (yellow, light yellow, blueish gray and gray) in appearance are induced by controlling the molar ratio of titanium ...
