摘要

Ru/Nb2O5对糠醛的水还原转化有较好的效果。系统表征、动力学研究和原位漂移实验表明，钌+的丰度与底物、关键中间体和产物（糠醛、2-环戊酮和环戊酮）的吸附行为高度相关，从而决定了FFR的转化率和类环戊酮的选择性。

Correlation of the catalytic performance with Ruδ+ species on Ru/Nb2O5 in furfural aqueous reductive conversion†

Ru/Nb₂O₅ is effective for furfural aqueous reductive conversion. Systematic characterization, kinetic studies and in situ DRIFT tests demonstrated that the Ru^δ+ species abundance is highly correlated with the adsorption behavior of the substrate, key intermediate and product (furfural, 2-cyclopentenone, and cyclopentanone), which governs the FFR conversion rate and cyclopentanoid product selectivity.
