为实现生物质与废塑料高效资源化协同利用,以水稻秸秆(RS)与聚氯乙烯(PVC)为原料,采用共热解方法,制备高性能电容炭材料(PR),探讨共热解工艺的反应路径及PR的结构与性能之间构效关系。采用焦耳加热装置进行快速共热解实验,通过改变热解温度(
t
=500、600、700、800 ℃)和原料配比(
m
(PVC)∶
m
(RS)=3∶1、2∶1、1∶1、1∶2、1∶3),制备一系列多孔PR。采用热重分析仪(thermogravimetry-derivative thermogravimetry,TG-DTG)、扫描电子显微镜(scanning electron microscope, SEM)、拉曼光谱(Raman spectroscopy, Raman)及傅里叶变换红外光谱(Fouri
er transform infrared spectroscopy, FTIR)等表征PR的微观形貌、石墨化程度及官能团特征;采用三电极体系测试PR的双电层电容储能性能及电催化析氢反应(hydrogen evolution reaction,HER)性能。结果表明,在RS、PVC共热解体系中存在显著正协同效应,RS能够有效降低PVC的起始分解温度,提高热解速率;随着
t
升高,PR的石墨化程度和缺陷密度(

To achieve the efficient and synergistic resource utilization of biomass and waste plastics, a co-pyrolysis method of rice straw (RS) and polyvinyl chloride (PVC) was employed to prepare high-performance capacitor carbon materials (PR). This study investigates the reaction pathways of the co-pyrolysis process and the structure-performance relationship of PR. A Joule heating device was used for rapid co-pyrolysis experiments, where the pyrolysis temperature (
t
=500, 600, 700, 800 ℃) and the material ratio (
m
(PVC)∶
m
(RS)=3∶1, 2∶1, 1∶1, 1∶2, 1∶3) were adjusted to produce a series of porous PRs. The micro-morphology, graphitization degree, and functional group characteristics of PR were characterized using thermogravimetry-derivative thermogravimetry (TG-DTG), scanning electron microscopy (SEM), Raman spectroscopy, and Fourier transform infrared spectroscopy (FTIR). The electrochemical double-layer capacitance storage performance and hydrogen evolution reaction (HER) performance were tested using a three-electrode system. The results indicate a significant positive synergistic effect in the RS and PVC co-pyrolysis system, where RS effectively lowers the initial decomposition temperature of PVC and enhances the pyrolysis rate. As the
temperature increases, the graphitization degree and defect density (
I
D
/
I
G
) of PR increase; however, when
t
>
700 ℃, the pore structure of PR collapses, hindering ion transport in the electrolyte. When
t
=600 ℃ and
m
(PVC)∶
m
(RS)=1∶3, the pyrolyzed PR exhibits a hierarchical porous structure and suitable defect structure (

/

G
≈2.0), demonstrating optimal electrochemical performance, with the electrochemically active surface area corresponding to the double-layer capacitance (
C
dl
) reaching its maximum value (1.318 5 μF/cm²) and exhibiting the lowest hydrogen evolution overpotential. The incorporation of RS not only constructs a developed ion transport channel but also mitigates the adverse effects arising from the PVC pyrolysis process through the synergistic effect, providing a reference for the development of low-cost, high-performance carbon-based energy storage materials.
