Synthesis gas can be converted into a number of important energy carriers and fuels and it is playing a growing role in the energy sector. In this work oxy-steam reforming of methane was performed over a modified 5%Ni/SiO2 catalyst in a fixed bed reactor at atmospheric pressure with the aim of producing syngas with high yield. The modified catalyst was synthesised by oleylamine-assisted impregnation...
Capacitive humidity sensors were fabricated using countersunk interdigitated electrodes coated with amorphous nanostructured TiO2, SiO2, and Al2O3 thin films grown by glancing angle deposition. The capacitive response and response times for each sensor were measured. The sensor utilizing TiO2 exhibited the largest change in capacitance, increasing exponentially from ~ 1 nF to ~ 1muF for an increase...
The main conditions of physical model of hydrogen influence on Pd-SiO2-n-Si MOS-diodes are presented. It is proposed that hydrogen atoms (Ha) occurred due to dissociation of H2 molecules on the surface of Pd electrode diffuse through Pd and SiO2 layers and are adsorbed on Pd-SiO2 and SiO2-n-Si boundaries. It has been showed that in contrast to MOS-capacitor the response to hydrogen is generated due...
We have investigated the infrared spectra for CO adsorbed on silica supported Ru/Fe alloys at various CO partial pressures and varying mole fractions of Ru and Fe within the frequency range of 1500 cm/sup -1/ /spl sim/ 2500 cm/sup -1/. Four bands (2080.0 cm/sup -1/, 2028.0 cm/sup -1/, 1934.0 /spl sim/ 1970.9 cm/sup -1/, 1621.8 cm/sup -1/) were apparently observed for the 4% Ru/Fe-SiO/sub 2/ sample...
