Research Topic

Renewable Energy via Photo Catalytic Reduction of CO2
CO2 can be converted to hydrocarbons via photo reduction using photocatalyst, that is, mimic to photosynthesis. Such route has the advantages of both renewable energy and CO2 remedy. TiO2 and Cu/TiO2 were synthesized by a sol-gel method using a homogeneous hydrolysis technique. The photocatalytic reduction of CO2 was performed in aqueous solution. Major hydrocarbon product was methanol, which can be use as fuel or raw chemicals. The photocatalytic efficiency of Cu/TiO2 was significantly increased because of lowering the re-combination probability of hole-electron pairs. Characterization of Cu/TiO2 indicated that Cu+ was active site, and an optimum Cu loading/dispersion was required to give maximum methanol yield.

 

Visible-light response photocatalyst
The doping of transition metal in titania can extend the adsorption of UV to visible- light region. In the photocatalytic de-colorization of methyl blue, V/TiO2 was proved to be a visible-light response catalyst. The study indicated that the ion of V4+ was highly dispersed within the tetrahedral structure of TiO2.

 

Novel Boron Nitride Catalyst
This invention first demonstrated boron nitride (BN) as a catalyst support. BN supported Pt catalyst was applied to incinerate VOC (volatile organic compound) in polluted air. The complete oxidation of gasoline, BTX(benzene, toluene and xylene) and methanol were performed in a steady-state flow reactor. The activity of Pt/BN was higher than that of traditional alumina support. The oxidation could be ignited at low or near room temperature, and maintained its high activity for a long period of time. The research showed that BN provided unique metal-support interaction, which enhanced the activity of Pt.
