The results of this study demonstrate that deoxidized PdO thin films can be applied for use in the creation of high-sensitivity hydrogen sensors.
The results of the present study have significance to heterogeneous catalysis on such supported metal catalysts.It does not show up in our cata- lysts, even in those subjected to a re- crystallizing heat treatment at 1100C under an inert atmosphere.This process is experimental and the keywords may be updated as the learning algorithm improves.In the case of WO, the presence of pal- ladium produced a relatively smaller de- crease of reduction temperature (30C) to both the intermediate oxide and the metal.1 for the three oxides show that the presence of 1 wts palladium caused a decrease in the tem- perature required for onset of reduction.Acta 2, 216-218 (1968).Chemistry experiments, burning, palladium with hydrogen, danger: Coolness: Difficulty: Published on Fire, heating with fire, explosion, poisoned gas, organic.300 notes, references.Oxide 25 1 I I 0 loo.Umanskii, X-Ray Diffraction Investigation of Metals in Russian, Metallurgizdat, Moscow (1960).At lower temperatures, reduction to inter- mediate oxidation states is apparent from the inflections in the curves and marked carte cadeau spirit liste magasin by arrows.By means of thermogravimetric analysis (TGA we investigated the effect of palladium on the rates of hydrogen re- duction of three powdered metal oxides, Moos, WO, and Fe, Oy (Matheson, Cole- promo code for t mobile apple watch man and Bell, reagent; Sylvania Electric Products ; and Baker, reagent; respec- tively).Palladium was applied to the oxides by slurrying 1 g of each of the metal oxides with 1 ml of a solution of palladium chloride.06 N HCl, and by subsequent evaporation of the solution to dryness at 130C in air for.The sensitivity of the PdO thin films was found to be as high.H., The Chemistry of Some Hydrodesulfurization Catalysts Containing Molybdenum, Climax Molybdenum.

The only known mixed sulfide, CoMoS, (7, 8 has a very low catalytic activity when tested under the same ccn- ditions.
By this criterion intermediate oxide reduction of MoOa appears to start 400C lower than it does in the absence of palladium.Electricity, solution, oxidation reduction, color change, precipitate.Received March 9, 1971.First, cer- tain metal oxide impurities, either indige- nous to the catalyst or deposited from the feedstream, may be reduced readily and alter the character of the catalyst.Blokhin asnoyarsk Institute of Nonferrous Metalsussr, cite article.Met., Krasnoyarsk (1984 Manuscript.The final weight losses measured corre- spond to complete reduction to metal, within -tO.7 of the theoretical values.2010 Apr 1;48(4 347-352).
Thermogravimetric analyses during hy- drogen reduction of the metal oxides MoOa, WO, and FezOa (Curve A) and of the metal oxides with 1 wt palladium (Curve B).
Under these conditions, the X-ray patterns showed the lines of the hexagonal and rhombohedral forms of MO and those of the cubic form of co,.
