不同浓度Na2CO3催化的木聚糖衍生炭的结构与电化学性能研究
Comparative study on the structural properties and electrochemical performance of xylan-derived char catalyzed by Na2CO3 at various concentrations
摘要
Abstract
In this study,the catalysis function of Na2CO3 to the structural properties of xylan char was well investigated with Na2CO3 on,and the electrochemical performance of xylan char as an anode material for sodium-ion batteries was tested.The characterization of X-ray microscopy and scanning electron microscopy demonstrated that the morphological structure of xylan char was altered due to the addition of Na2CO3 catalyst.The increasement of the Na2CO3/xylan ratio resulted in a slenderization of the triangular prism shape of the char skeleton and a reduction in porosity.X-ray diffraction analysis revealed that Na2CO3 promoted the growth of the(004)crystal plane of graphite during xylan pyrolysis,while inhibiting the formation of the(100/101)crystal planes.Raman spectroscopy analysis indicated that the presence of Na2CO3 had changed the graphitization degree of xylan char.Electrochemical tests further showed that char prepared with a Na2CO3/xylan mass ratio of 1∶1 exhibited the highest sodium storage capacity.This study provides a pathway for the rational design carbon materials derived from xylan for future applications in energy storage devices.关键词
