Solar-driven CO₂ reduction using modified earth-abundant ilmenite catalysts.

ABSTRACT: Photocatalytic CO₂ reduction is an alternative technology to the depletion of highly pollutant fossil fuels through the generation of renewable solar-based fuels. This technology requires that the photocatalysts be obtained directly from nature to scale up the process. Taking that into consideration, this work proposed the fabrication of sodium iron titanate (NaFeTiO₄) photocatalysts from earth-abundant ilmenite mineral. The photocatalysts exhibited full spectrum light response, good electron transfer due to its unique tunnel structure that favored the formation of rod-like morphology. These properties promoted the solar-driven CO₂ reduction to generate formic acid (HCOOH) with high selectivity (157 μmol g^-1 h^-1). It was found that hig
