“…[ 13 ] In contrast to Pt, carbon-based materials can be produced in scalable quantity at low cost, and they have better corrosion stability in DSSCs. As a result, carbon blacks, [ 14 ] carbon nanoparticles, [ 15 ] carbon nanotubes, [ 16,17 ] and graphene nanosheets [18][19][20][21][22] have been widely studied in hopes of fi nding promising alternatives to Pt-based materials. Their electrocatalytic activities are not comparable to Pt for the conventional I − /I 3 − redox couple, but graphene-based CEs outperformed the conventional Pt CEs in the Co-based mediators that have been reported.…”

Challenging precious Pt-based electrocatalysts for dye-sensitized solar cells (DSSCs), graphene nanoplatelets that are N-doped at the edges (NGnPs) are prepared via simply ball-milling graphite in the presence of nitrogen gas. DSSCs based on specific nanoplatelets designated "NGnP5" display superior photovoltaic performance (power conversion efficiency, 10.27%) compared to that of conventional Pt-based devices (9.96%). More importantly, the NGnP counter electrode exhibits outstanding electrochemical stability and electrocatalytic activity with a cobalt-complex redox couple.

“…A method formed carbon shells on silica nanoparticles templates under extreme heat which was etched away using harsh chemicals [8]. Nitrogen doped hollow carbon nanoparticles have been assembled by detonation-assisted chemical vapor deposition method [9,10]. Hollow fluorescent carbon nanoparticles were produced by the carbonization of acetic acid using a highly exothermic reaction between water and P 2 O 5 , which only formed cross-linked carbon nanoparticles [11].…”

“…These could be attributed to the large void space yielded from the removal of iron nanoparticles, which is in good agreement with TEM results. Remarkably, a sharp drop at P/P 0 = 0.5 in the desorption branch of GCS-1000 (after Fe removal) depicts the phenomenon of a large pore encapsulated by a matrix with relatively small pore sizes [20,21]. Therefore, hierarchical pore size distribution in the micro-and macroporous regions is recognized, which endows a high the BET surface area of 381 m 2 g -1 and a large pore volume of 0.45 cm 3 g -1 for GCS-1000 (after Fe removal).…”

Graphitic carbon spheres (GCS) with uniform particle diameter have been synthesized by K 3 [Fe(CN) 6 ] catalytic graphitization of resorcinol/formaldehyde (RF) precursors. XRD and Raman spectra reveal that highly graphitic structure is developed by catalytic graphitization at 1000°C successfully. The catalytic graphitization by K 3 [Fe(CN) 6 ] maintains the spherical morphology of the RF resins, resulting in GCS-1000 (1000 = catalytic graphitization temperature of 1000°C) with graphitic spherical morphology (625 nm in diameter). Besides conventionally microporous structure of carbonized RF resins, macropores with the diameter about 100 nm are yielded from the removal of iron particles, leading to hierarchical micro/macroporous structure and high surface area (381 m 2 g -1 ). With a high degree of graphitization and prominent hierarchical porous structure, GCS exhibit a high capacitance of 155 F g -1 and a good electrochemical stability, which make this type of GCS promising candidates as electrode materials for supercapacitors.
