Then the extra VO3− around the FeVO4 colloidal particles can react with unstable Fe(OH)3, resulting the phase transformation from α-Fe2O3 (47.99–7.16%) into FeVO4 (52.01–92.84%), promoting photocarriers' generation capacities. After final carbonization, a part of C atoms enter into...
A composite of γ–Fe2O3 γ–Fe2O3 and acetylene black (AB) was fabricated by the thermal treatment of a composite of γ–FeOOH γ–FeOOH and AB synthesized by an aqueous solution method. In the composite, acicular γ–Fe2O3 γ–Fe2O3 particles (20×200nm) (20×200nm) were o...

After final carbonization, a part of C atoms enter into lattices of α-FeOand FeVO, forming impurity levels and oxygen vacancies to increase effective light absorptions. Another part of C sources turn into interfacial carbon layers to bring fast charge transfer by decreasing the charge transition ...
According to this analysis it is found that for Fe2O3 the z.p.c. agrees with the pH of minimum solubility of the oxide and with the isoelectric pH as determined by the positively and negatively charged Fe(III) hydroxo-complexes in solution. Although limited experimental data are available,...

The zero-point-of-charge of a natural specular hematite in aqueous sotution has been determined as pH 8.68 ± 0.12, and that of synthetic zirconia as pH 6.05 ± .04. The adsorption density of the potential-determining ions was found by potentiometric titration and the surface charge and diffe...
As one of the most prevalent metal oxides on Earth, iron oxide, especially α-Fe2O3 or hematite, has been the subject of intense research for several decades. In particular, the combination of a relatively small bandgap and related visible light absorption, natural abundance, low cost, and ...
