WebAs shown in Figure 9e, due to the difference in electronegativity between P and B, the production of partially positively charged Co (Co δ+) is promoted. In the Volmer step, the undercoordinated Co δ+ and the dangling P (P δ− ) interact with O and H in H 2 O, respectively, which enhances the adsorption of H 2 O and weakens the HO H bond of the … WebTranscribed Image Text: 1/what is the main difference between hydrothermal and Solvothermal methods for synthesis of Nanoparticles? which of them is cheaper ?
