Abstract
A photocatalyst can be regenerated with increasing efficiency, turnover number and turnover frequency in the presence of air by irradiating the photocatalyst with a first range of wavelengths of light that excite the photocatalyst to an intermediate and irradiating the intermediate with a second range of wavelengths of light that turns the intermediate to the photocatalyst.
