Facet-dependent photocatalytic reduction of CO2 on BiOI nanosheets

We first report the facet controllable synthesis of BiOI nanosheets with exposed {0 0 1} (BiOI-001) and {1 0 0} (BiOI-100) facets by adjusting reaction time of hydrothermal process. Photocatalytic results revealed the facet-dependent photocatalytic property for CO2 reduction on BiOI nanosheets.95
