Graphene-based cathodes for liquid-junction dye sensitized solar cells: Electrocatalytic and mass transport effects

“…From other carbon-based materials and works (not listed in Table 1) we should mention hard carbon spherules [94], activated carbon [95], graphene [96][97][98][99][100][101], nitrogen-doped graphene [102], HNO 3 treated graphene [103], graphene-W composite [104], Pt-reduced graphene oxide composite [105], SWNT [106], MWNT [107][108][109] and N-doped nanotubes [110]. MWNT were also assembled in composites with conducting polymer [107] and TiN [111].…”

Facile synthesis of decorated graphene oxide sheets with WO3 nanoparticles

“…So far, several methods have been reported to attach nanoparticles to graphene oxide or graphene [16][17][18]. Nanostructure of tungsten trioxide (WO 3 ) is one of the metal oxide nanoparticles, which can modify the GO properties [17][18][19][20].…”

“…It was reported that the combination of WO 3 with graphene oxide sheets improves significantly its conductivity [17,25]. Several methods were studied to synthesize graphene-based nanocomposites, including grinding method [26], chemical synthesis [17,27] and sonochemical method [18]. In these methods, the nanoparticles usually attach to the GO sheets by formation of weak bond.…”

Sulfur‐Doped Graphene with Iron Pyrite (FeS2) as an Efficient and Stable Electrocatalyst for the Iodine Reduction Reaction in Dye‐Sensitized Solar Cells

“…The ideal CE materials for DSSCs should possess not only high electrical conductivity, but also excellent catalytic activity and stability . A wide range of alternative materials have been explored as electrocatalysts for IRR in DSSCs . Graphene nanosheets doped with heteroatoms, such as sulfur (S), nitrogen (N), boron (B), phosphorous (P), show great promise as catalysts for the IRR in DSSCs owing to their high surface area and good conductivity.…”
