Raül Díaz4, Carmen Force5, Aziz Genç6, Jordi Arbiol6, Pietro Siciliano1, Elisabetta Comini7,8 & Isabella Concina9 SnO2 nanocrystals were prepared by precipitation in dodecylamine at 100 °C, then they were reacted with vanadium chloromethoxide in oleic acid at 250 °...
Third, ethanol is a typical reductive gas, so when the sensor is exposed to ethanol gas, ethanol can react with the adsorbed oxygen species leading to the release of adsorbed electrons, the thinning of depletion layer at the oxides surface, and the decrease of energy barrier height at the ...
These molten salts infiltrate through any TBC defects such as pores and cracks, and react mainly with the Y 2 O 3 phase, promoting the destabilization of the t′-phase [12], [13], [14]. This failure mechanism is known as salt-induced hot corrosion (HC) attack, the main reactions ...
Many kinds of NH3 forms present on the catalyst surface, but only NH4+ on Brønsted acid sites and a small portion of NH3 on Lewis acid sites are reactive with NO at 250 °C or below, and most of the NH3 on Lewis acid sites does not react with NO, regardless the presence of ...

This may be due to the fact that the catalyst prepared by the low-temperature in-situ growth method does not cause sintering, and MnOx is dispersed in the catalyst carrier evenly. The surface dispersibility is good, so that the active component is more easily contacted with the reducing gas ...
Likewise, photogenerated holes can directly interact with RB molecules. Figure 11. Quenching experiments of the proposed mechanism. The resulting holes bear a positive charge, which attracts the adsorbed water molecules on the surface of the nano-catalysts and reacts with them to introduce OH- ...
The reason behind the superior corrosion resistance of GdYb-YSZ coatings when compared to YSZ coatings can be explained by the Lewis acid–base mechanism. According to this mechanism, acidic V2O5 reacts more easily with oxides having a higher basicity [40]. GdYb–YSZ coatings contain more rare-...
