摘　　要：Efficient and applicable catalysts are highly desirable for advanced biomass transformation industry,here,we fabricated a series of Nd-Co-P catalysts for hydrogenation of furfural(FAL)to furfuryl alcohol(FOH).By comprehensive characterizations,it is demonstrated that the prepared Nd-Co-P samples are structured as(NdPO_(4))_(m)/Co_(2)P nanocomposites with molar ratio(m)in range of 0.24-1.1;by manipulating m,the outstanding catalytic efficiency comparable with the performance of precious metal catalysts,such as turnover frequency(TOF)up to 0,50 s^(-1)(being ten-fold higher than Co_(2)P)and FOH yield up to97%,is achieved on the reusable(NdPO_(4))_(m)/Co_(2)P composites.Te mperature programmed desorption(TPD),in-situ infrared spectroscopy(IR)and kinetic-mechanism studies further disclose that Co_(2)P is decisive for activating FAL,instead,NdPO_(4)possesses unique capability of activating hydrogen which readily facilitate the selective hydrogenation of FAL to FOH through a rapid Langmuir-Hinshelwood process over(NdPO_(4))_(m)/Co_(2)P catalyst.These results indicate that rare-earth phosphates like NdPO_(4)can act as the promising and reliable catalytic component to activate hydrogen,which can be of interest not only for innovating novel and applicable non-metallic catalysts for sustainable biomass transformation analogous to hydrogenation of FAL,but also for expanding material base for other green mass transformation techniques involving hydrogen.
