Photothermal conversion capability characterizations of BiVO4/Fe3O4@PDA SPs. Temperature increments vs. the proportions of Fe3O4 in BiVO4/Fe3O4@PDA SPs (200 µg/mL SPs; 1 W/cm2 irradiation) (a), the power densities of incident laser (200 µg/mL BiVO4/Fe3O4-2@PDA SPs) (b), the concentrations of SPs (BiVO4/Fe3O4-2@PDA SPs; 1 W/cm2 irradiation) (c). The molar ratios of BiVO4:Fe3O4 in SPs from BiVO4/Fe3O4-1 to BiVO4/Fe3O4-3 are 10.5:1, 5.4:1 and 3.6:1
