affects the ability of sorbed oxygen, whereas B-site substitution influences the activity of sorbed oxygen [93]. And their catalytic mechanism for ORR and OER was simply depicted in Figure 2. As shown...: O2+2H2O+2e→OH2-+OH- And the OER on the oxide proceeds through the following mechanism: Mz+OH-→Mz-OH+e Mz-OH+OH-→Mz-H2O2+e H2O2+OH-→HO2-+H2O H2O2+HO2-→H2O+OH-+O2 Figure 2 Illustration of O2 catalyzed......

to the packing theory, only the poorly sorted debris can be packed into deposits with a low porosity and pore-throat size. Based on the analysis of the mechanism, the high strengths of the tested debris......
the change trend of the specific surface area of biochars. This is mainly due to the complex adsorption mechanism of methylene blue by biochar, including ion exchange, functional group complexation, π-π.... The biochars prepared from four SS feedstocks exhibit different adsorption ability of methylene blue, especially at low dosage of biochar.

, coarse ones can speed up the recrystallization through the particle stimulating nucleation (PSN) mechanism [55-57]. As depicted in Fig. 12(c) after the first cycle more elongated and large Mg17Al12 particles exist, which makes the PSN as the major mechanism after the first cycle. However, at the same time, fine particles are available, which plays the role of the pinning effect. The newly nucleated......
