研究目的
Investigating the enhancement of supercapacity under sun illumination of electrodes fabricated from cavitated nanoporous carbon carbonized from iodine doped β–cyclodextryn.
研究成果
The study demonstrates a significant enhancement of supercapacity under sun illumination for electrodes fabricated from cavitated nanoporous carbon carbonized from iodine doped β–cyclodextryn. This effect is attributed to light-generated carriers in low-dimensional nano-interfaces, which increase the concentration of delocalized electrons and unlock the Helmholtz layer capacity. The findings suggest a promising direction for the development of high-performance supercapacitors.
研究不足
The study does not explore the long-term stability of the supercapacity enhancement under continuous illumination or the scalability of the synthesis process for industrial applications.
