Fig. 4. (a) The peak area of hydroxyls in FTIR normalized by SBET (×103) on 2.5 wt% RhFeLi/TiO2 NRs, 2.5 wt% RhFeLi/TiO2 Com and 2.5 wt% RhFeLi/TiO2 NRs-CO. (b) CO-TPD profiles of 2.5 wt% RhFeLi/TiO2 NRs. Pretreatment: H2 reduction at 400 °C. (c) CO-TPD profiles of 2.5 wt% RhFeLi/TiO2 Com. Pretreatment: H2 reduction at 400 °C. (d) CO-TPD profiles of 2.5 wt% RhFeLi/TiO2 NRs. Pretreatment: CO reduction at 350 °C.
