BiOI can be used for photocatalytic reduction of CO{sub 2} into hydrocarbon fuels under sunlight. - Highlights: • Room temperature synthesis of BiOI flowerlike hierarchical structures. • BiOI can be used for photocatalytic reduction of CO{sub 2} into hydrocarbon fuels under sunlight. • The photocatalytic activity of BiOI is higher than that of P25 TiO{sub 2}. - Abstract: BiOI flowerlike hierarchical structure was synthesized by the direct hydrolysis method – hydrolysis at room temperature in the presence of polyvinyl pyrrolidone. As-synthesized BiOI was characterized by powder X-ray diffraction, UV–vis diffuse reflectance spectra, X-ray photoelectron spectroscopy spectra, scanning electron microscopy, transmission electron microscopy, and high-resolution transmission electron microscopy. It is a facile way to obtain BiOI flowerlike hierarchical structure photocatalyst for photocatalytic reduction of CO{sub 2} into hydrocarbon fuels under simulated sunlight irradiation without cocatalyst. And the photocatalytic activity of as-synthesized BiOI is higher than that of P25 TiO{sub 2} and bulk BiOI.
