Utilization of waste vanadium-bearing resources in the preparation of rare-earth vanadate catalysts for semi-hydrogenation of α,β-unsaturated aldehydes
文献摘要：
Recycling industrial solid waste not only saves resources but also eliminates environmental concerns of toxic threats.Herein,we proposed a new strategy for the utilization of petrochemical-derived carbon black waste,a waste vanadium-bearing resource(V＞30000 ppm(10-6)).Chemical leaching was employed to extract metallic vanadium from the waste and the leachate containing V was used as an alternative raw material for the fabrication of vanadate nanomaterials.Through the screening of various metal cations,it was found that the contaminated Na+during the leaching process showed strong competitive coordination with the vanadium ions.However,by adding foreign Ce3+and Y3+cations,two rare-earth vanadates,viz.,flower-like CeVO4 and spherical YVO4 nanomaterials,were successfully synthesized.Characterization techniques such as scanning electron microscopy,transmission electron microscopy,X-ray diffraction,energy-dispersive X-ray spectroscopy,Fourier-transform infrared,and N2 physisorption were applied to analyze the physicochemical properties of the waste-derived nanomaterials.Importantly,we found that rare-earth vanadate catalysts exhibited good activities toward the semi-hydrogenation of α,β-unsaturated aldehydes.The conversion of cinnamaldehyde and cinnamic alcohol selectivity were even higher than those of the common CeVO4 prepared using pure chemicals(67.2％vs.27.7％and 88.4％vs.53.5％).Our work provides a valuable new reference for preparing vanadate catalysts by the use of abundant vanadium-bearing waste resources.
