Poor crystallinity
WebFeb 16, 2024 · The doping concentration increases as the PPy crystallinity becomes poor in experiment, while the carrier density increases as well. Thus, it can conclude that the transport property change from metallic-like to semiconducting is related to the increase of charge carrier density (corresponding to the gradually decrease of FeCl 3 concentration). WebThis can be explained as follow: At low reduction temperature the accumulation of P on the surface of catalyst was serious (Table 2), which would lead to poor CO uptake, while at …

WebNov 20, 2024 · Polymers can be amorphous or crystalline, depending upon a number of factors including the shape of their repeat unit, their molecular weight and their thermal history. Crystallinity in polymers is more complex than in other materials because of the long polymer chains. In some areas, the polymer chains align and pack together to form … WebOxidative coupling of methane (OCM) is a promising method for the direct conversion of methane to ethene and ethane (C 2 products). Among the catalysts reported previously, Mn 2 O 3-Na 2 WO 4 /SiO 2 showed the highest conversion and selectivity, but only at 800° to 900°C, which represents a substantial challenge for commercialization.
