“…5 These observations demonstrate that Ag 3 PO 4 plays a vital role on the formation of nanoplate morphology of a-Fe 2 O 3 . In our previous report (Liu et al, 2015), a similar nanoplate structured aFe 2 O 3 film was formed during hydrothermal process in an aqueous solution of FeCl 3 and Na 2 HPO 4 . Phosphate ions were preferentially adsorbed on certain planes of the initial nuclei, and iron ions (or iron oxides units) continued to grow and aggregate along other planes, resulting in formation of the nanoplate structure.…”

“…Therefore, the Ag-doped a-Fe 2 O 3 nanoplates via solid-phase synthesis will be predicted to be effective in PEC water splitting. Furthermore, phosphate ions absorbed on the surface of a-Fe 2 O 3 nanoplates will build up a negative electrostatic field, which can promote charge separation and extraction of holes to the electrode surface, resulting in minimizing surface charge recombination (Kim et al, 2014;Liu et al, 2015). A schematic diagram for conversion of FeOOH nanorods to a-Fe 2 O 3 nanoplates mediated by Ag 3 PO 4 was shown in Fig.…”

“…Samples mediated with varied concentrations of NaMoO 4 of 0.3, 0.45, 1.5, 3 mmol/L were referred to as Fe to the FeOOH [49], which would affect the crystallization of FeOOH. In our earlier study [50], the adsorption of phosphate groups (PO 4 3+ ) on the certain planes of FeOOH nuclei was also found to affect the growth of FeOOH, leading to the formation of an ultrathin nanocube-structured FeOOH film. FIG.…”
