Abstract: Spectral up-conversion (UC) has been attracting growing interest for the effective harvesting of the near-infrared (NIR) part of sunlight for photocatalytic hydrogen production and environmental purification. We present evidence of NIR-to-UV-VIS photon conversion for degradation of organic dyes and hydrogen and oxygen evolution via water-splitting by TiO<subscript>2</subscript> and Rh–Cr oxide-loaded SrTiO<subscript>3</subscript>:Al photocatalysts, respectively.
