Development of Novel Proton Conductors Consisting of Solid Acid/pyrophosphate Composite for Intermediate-temperature Fuel Cells
Intermediate-temperature fuel cell Composite electrolyte Solid acid Pyrophosphate Composite effect
2010/9/8
Fuel cells are attractive energy conversion devices with high efficiencies and low emissions, and many studies have been conducted so far. Among them, fuel cells operating at 200-600°C are promising t...
Selective Oxidation of n-Butane over Highly Crystalline Vanadyl Pyrophosphate Catalyst Synthesized by Intercalation-exfoliation-reduction of Layered Vanadyl Phosphate Dihydrate
Exfoliation Vanadium-phosphorus oxide Selective oxidation n-Butane
2009/8/4
A novel synthetic method to prepare a highly crystalline (VO)2P2O7 catalyst by the intercalation-exfoliation- reduction of VOPO4·2H2O in alcohol is presented. Stepwise thermal treatment of layered VO...
The Role of Brønsted and Lewis Acid Sites of Vanadyl Pyrophosphate Measured by Dimethylpyridine-temperature Programmed Desorption in the Selective Oxidation of Butane
Vanadyl pyrophosphate catalyst Acidic property Dimethylpyridine Temperature programmed desorption
2009/7/24
Acidic properties of three types of (VO)2P2O7 catalysts were investigated by temperature programmed desorption (TPD) using 3, 5- and 2, 6-dimethylpyridine as probes, and the selective oxidation of but...
