In-situ infrared and X-ray absorption spectroscopy were used to investigate the effect of Li and Mn promoters on the catalytic and structural properties of Rh/TiO2 for CO hydrogenation.  Our results show that both promoters decrease the reducibility of supported Rh, which correlates strongly with increased selectivity to ethanol.
