电化学还原处理对碳纸形貌和电化学电容的影响
Electrochemical Reduction Effects on the Morphology and Electrochemical Capacity of Carbon Paper
摘要
Abstract
We studied the changes in the morphology and electrochemical capacity of carbon paper caused by the electrochemical reduction. SEM images show that the electrochemical reduction caused the decomposition of reduced carbon papers( rCPs) into carbon particles and rough surface. Raman spectra show the surface disorder as evidenced by higher ID/IG ratio for treating time as short as 1 min. BET tests reveal the markedly increased specific surface area caused by the electrochemical reduction of carbon paper. XPS analyses show a higher quantity of surface hydroxyl species( C—OH) on rCPs. The capacitance of rCP( treated at-1. 6 V for 5 min) is 15 times that of the pristine car-bon paper, and this outstanding capacitance is rather stable even after prolonged charge-discharge 1500 cycles.关键词
