摘要
为了促进油茶粕资源化处理,该文提出了使用油茶粕制备优异碳负电极的研究路线,期望能够推动油茶粕资源化处理持续向好发展.首次利用熔融盐淬火法制备油茶粕衍生碳材料,经研究发现:油茶粕熔融盐650℃下焙烧60 min后淬火制备的碳材料负电极在电流密度为0.5 A/g下,比电容高达232 F/g;熔融盐能作为模板剂保护碳不被氧化,K元素对材料具有刻蚀作用,这可有效提高材料的孔隙结构,淬火过程不能增加碳材料的比表面积,但促进了电子的传质和转移速率.该研究为解决油茶粕增值问题和设计适合实际应用的碳材料提供了可行的方法.
Abstract
In order to promote the resource treatment of camellia seed meal,the research route of using camellia seed meal to prepare excellent carbon negative electrode is proposed in this paper,which is expected to promote the sustainable development of the resource treatment of camelilla seed meal.In this paper,a simple green treatment method was proposed to prepare oil-tea-meal-derived carbon materials by molten salt quenching method for the first time.It was found that the specific capacitance of the carbon negative electrode prepared by the molten salt of camellia seed meal roasted at 650 ℃ for 60 min and then quenched was as high as 232 F/g at a current density of 0.5 A/g;the molten salt could be used as a template agent to protect carbon from being oxidized,the K element has an etching effect on the material,which could effectively improve the pore structure of the material,and the quenching process could not only increase the specific surface area of the carbon material,but also promote the mass transfer and transfer rate of electrons.This study provides a feasible method for solving the problem of increasing the value of camellia seed meal and designing carbon materials suitable for practical application.
