Large Electrical Resistance Variation at Low Temperature in Transition Metal-Doped Ge Single Crystals

Many transition metal oxides supported on TiO2 have been studied for selective catalytic reduction (SCR) of NO with NH3. However, the trade-off exists between the low-temperature activity and N2 selectivity....

Metal Doped

Mn-Ce based catalysts doped with transition metal were synthesized via a sol-gel method for low-temperature Selective catalytic reduction DeNOx. NOx conversion of these catalysts was evaluated under 100 OC-300 OC. H2-Temperature Programmed Reduction was used to investigate the reduction capability effect on NOx conversion. On this basis, sulfur resistance of catalysts was analyzed and Fourier Transform Infrared (FI-IR) spectra were used to discuss sulfur poisoning mechanism of catalysts. The results indicated that NOx conversion of catalysts was Mn-Ce-W0.03 Mn-Ce-Y0.03 > Mn-Ce-Zr0.03 > Mn-Ce >Mn-Ce-La0.03 > Mn-Ce-Pr0.03.W, Zr, Y elements was doped to improve catalytic activity at low-temperature and enhance anti-sulfur ability of catalysts. Especially, W element can restrain sulfate formation and reduce the channel blocking of the catalyst and Mn-Ce-W0.03 catalyst displays optimal performance of resistance to sulfur poisoning.

Reversible Phase

An effective and convenient method about molybdenum metal thin film microcircuit was developed on diamond anvil cell(DAC) under high pressure. Alumina film was used as the protective layer and sputtered on DAC. By using this method, we studied the electrical resistance variation about nanoparticles ZnS power up to 36GPa. The reversible phase transition had been reflected clearly by the electrical resistance measurements with sample.
