What Makes the Photocatalytic CO2 Reduction on N-Doped Ta2O5 Efficient: Insights from Nonadiabatic Molecular Dynamics.

Abstract: Recent experimental studies demonstrated that photocatalytic CO2 reduction by Ru catalysts assembled on N-doped Ta2O5 surface is strongly dependent on the nature of the anchor group with which the Ru complexes are attached to the substrate. We report a comprehensive atomistic analysis of electron transfer dynamics in electroneutral Ru(di-X-bpy) (CO)2Cl2 complexes with X = COOH and PO3H2 attached to the N–Ta2O5 substrate. Nonadiabatic molecular dynamics simulations indicate that the electron transfer is faster in complexes with COOH anchors than in complexes with PO3H2 groups, due to larger nonadiabatic coupling. Quantum coherence counteracts this effect, however, to a small extent. The COOH anchor promotes the transfer with significantly higher frequency modes than PO3H2, due to both lighter atoms (C vs P) and stronger bonds (double vs single). The acceptor state delocalizes onto COOH, but not PO3H2, further favoring electron transfer in the COOH system. At the same time, the COOH anchor is prone to decom...

Control device for vehicular power transmitting apparatus

Abstract: A control device is disclosed which can obtain increased fuel economy performance depending on a kind of fuel in a vehicle having an internal combustion engine and an electric motor when the kind of fuel supplied to the internal combustion engine is altered. A determining vehicle speed (V1) and determining output torque (T1), representing a boundary value with which a step-variable control region and a continuously variable control region of a shifting mechanism (10) are demarcated, are altered such that the higher the mixing ratio of ethanol, the lower will be the determining vehicle speed (V1) and determining output torque (T1). Therefore, the determination is made whether to operate a first electric motor (M1) depending on the mixing ratio of ethanol, making it possible to obtain increased fuel economy performance in line with the mixing ratio of ethanol.
