OP-3-4LOW-TEMPERATURE CONVERSION OF ETHANOL OVERNi-Cu/SiO 2 CATALYSTLapin N.V., Bezhok V.S.Institution of Russian Academy of SciencesInstitute of Microelectronic Technology and High-Purity Materials, RAS,Chernogolovka, RussiaFax: (495)962-8047, E-mail: lapin@iptm.ruHydrogen is promising fuel for various power plants, low-power devices (1-50W)included. However, accumulation and storage of molecular hydrogen nowadayspresent a problem. One of possible pathways to overcome the difficulties can behydrogen production from hydrocarbons, e.g. alcohols (methanol or ethanol), bywater-vapor catalytic conversion. In this case ethanol has a number of advantagesover methanol such as low cost, low toxicity, ease of transporting, exploitation, andproduction from renewable sources (bioethanol). When hydrogen is used to supplyportable fuel cells, integration of a fuel cell and a fuel microchannel converter seemsmost perspective. In this case, the catalyst should be placed on the channel walls,where highly developed catalyst surface can hardly be obtained. In this work westudied low-temperature steam reforming of ethanol over a bimetal nickel-coppercatalyst deposited onto a quartz fiber of small specific surface.The main products of conversion are hydrogen, methane, carbon monoxide andcarbon dioxide. The conversion of ethanol starts at 200 °C and completes almost by90% at 350 °C. As the conversion proceeds, the concentration of all productsincreases. The concentration ratio of hydrogen, methane and carbon monoxideremains constant, with the hydrogen concentration being twice as high as those ofmethane and carbon monoxide. At 300 °C carbon dioxide appears in the gas phase,its content increases abruptly at 350 °C and makes 20 mol% at 400 °C. At thistemperature, the carbon monoxide concentration reaches the maximum and thendrops to 10 mol%, evidently due to the shift-reaction and carbon monoxidedisproportionation. The selectivity of hydrogen and methane slightly decreases (by10-15%) as the temperature rises because of an increase of CO 2 content in the gasphase; the selectivity of carbon monoxide reaches the maximum at 350 °C. Attemperature below 300 °C, the selectivity of carbon dioxide is low but increasesabruptly with temperature. Also the conversion of the ethanol-water mixture shouldproduce 2 moles of hydrogen per 1 mole of ethanol.72
OP-3-5HIGHLY SENSITIVE HYDROGEN GAS SENSORS SEMICONDUCTINGNANO WIRES GRAFTED WITH Pd NANOPARTICLESSeonghwa Ju 1 , Jun Min Lee 2 , Ha-Yeong 1 , Eunsongyi Lee 2 , Ji-eun Park 1 ,Wooyoung Lee 2 , Sung-Jin Kim 11 Department of Chemistry and Nano Science, Ewha Womans University,11-1 Daehyun-Dong, Seodaemun-Gu, Seoul 120-750, Korea, sjkim@ewha.ac.kr2 Department of Materials Science and Engineering, Yonsei University, Seoul 120-749We have investigated the hydrogen gas sensing performance of Pd nanoparticlegrafted single-walled carbon nanotubes (SWCNTs) and tin dioxide NWs. TheSWCNTs were modified with dendrimers and then Pd nanoparticles were grafted onthe dendrimers. The SWCNTs grafted with Pd nanoparticles resulted in highresponse (25%), a fast response time (7 sec) at 10,000 ppm hydrogen gas, and anultra-low concentration H 2 detection of 10 ppm in room temperature. Also, we havesuccessfully investigated hydrogen gas (H 2 ) sensors Pd nanoparticle-decorated tindioxide NWs. The SnO 2 network sensors were found to show ultra-high sensitivity(~ 1.2 × 10 5 %) and a fast response time (~ 2 s) upon exposure to 10,000 ppm H 2 atroom temperature. The hydrogen sensing mechanism in the SnO 2 network sensorshowing «ON–OFF switching» is mainly based on changes in the electricalconductance as the H atoms dissociated from H 2 due to the catalytic activity of PdNPs and «spill-over» effect with oxygen ions at the surface of SnO 2 . Further detailsrelated to the mechanisms of the SnO 2 network sensors will be discussed in thepresentation. This fabrication method using Pd nanoparticles as a catalyst for H 2molecules allows the production of highly-sensitive H 2 sensors that exhibit a broaddynamic detection range, a fast response time, and an ultra-low detection limit.References:[1].
