Oxidative steam reforming of ethanol is an effective way to produce high yields of hydrogen. A novel series of pyrochlore-type metal oxide of La2Ce2−xNi0.5xO7−1.5x (x=0.1–0.9) was prepared and its catalytic performance was studied. All the materials were characterized by X-ray powder diffraction (PXRD), inductively coupled plasma atomic emission spectrometer (ICP-AES) and temperature-programmed reduction...
Pyrochlore phases of Y2Ce2−xRuxO7 (x=0∼0.4) solid solutions were prepared with the sol-gel process and used as catalysts for the autothermal steam reforming of ethanol (AESR). The as-prepared samples were characterized with powder X-ray diffraction (PXRD), X-ray photoelectron spectra (XPS) and temperature-programmed reduction (TPR). The oxidation state of Ru ions was confirmed by XPS and TPR analyses...
A rapid and cost effective method for nanostructure fabrication in a large area was proposed in this paper. The integration of conventional ultra-violate lithography and self-developed technique was adopted to fabricate 700 nm nanocasts. Polydimethysiloxane (PDMS) was used to be a flexible mold material for the 2-inch wafer area uniform imprinted structures. This rapid structure fabrication technique...
A cost effective and high throughput imprinting technique is integrated to conventional light emitting diodes (LEDs) chip process to enhance the light extraction efficiency. Sub-micron surface texture composed of spin on glass (SOG) is directly imprinting onto the top of transparent conductive layer (TCL). The electrical performances of LED chips are not damaged after applying the sub-micron structure...
