Hollow core-shell structured mesoporous MWCNT/carbon nanofiber composites by electrospinning and silica template as counter electrodes for dye-sensitized solar cells
The multi-walled carbon nanotube (CNT)-embedded carbon nanofibers with hollow core/highly mesoporous shell stucture (CNT/Meso-HACNF) are prepared by concentric electrospinning using poly(methyl methacrylate) (PMMA) as a pyrolytic core precursor with either CNT/polyacrylonitrile (PAN) or fumed silica [...]
