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

Photocatalytic CO 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 (NaFeTiO) photocatalysts from earth-abundant ilmenite mineral.
