We present a theoretical study using Halgren-Lipscomb algorithm assisted by DFT + U to determine the catalytic mechanism for hydrogen production by steam reforming of methanol over CeO2 and Ni/CeO2 model catalytic surfaces. Our main goal is to descri

The reactivity of the PtNi supported on CeO2-nanorods was performance on methanol steam reforming (MSR). COads revealed that outer of the PtNi-catalyst could be mainly Pt-terminated and, COads was slightly attenuated on the surface of the CeO2-R. The
