Herein, the adsorbed oxygen species on the surface of GdFeO3 rods reacts with the target gas of reducing molecules, increasing the concentration of hole carriers, thus contributing to the response value of the sensor. In addition, the defect oxygen can act as active sites for molecule ...
This finding shows that the ratio of the fly ash mixture and biosorbent alone did not significantly impact the effectiveness of Hg removal—a small addition of material with an enriched chemical composition is sufficient and should be used in different applications such as carriers for carbon in ...
The size of spherical particles varied from 40 to 70 nm, while rod-shaped particles were more than 70 nm in length and 10–20 nm in width. The EDS spectra in Figure 8a have peaks for Fe, O and C, where Fe was 63% and O was 31%, which indicates the high purity of the ...
