Phosphorus-doped reduced graphene oxide as an electrocatalyst counter electrode in dye-sensitized solar cells

Few-layered ReS2 Nanosheets Grown on Carbon Nanotubes for Improved Hydrogen Evolution Reaction

“…The core 1s level peak of C can be deconvoluted into two peaks, as shown in Figure 1d. The sharp peak at 284.6 eV is attributed to the sp 2 hybridized graphite-like carbon atom [8]. The other peak at 286.0 eV is owing to the carbon atom bound to one oxygen atom.…”

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

“…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. Among the different doping atoms, S‐doped graphene (SGN) has to date yielded the most efficient electrocatalyst for IRR (also found in our preliminary investigation, see Supporting Information (SI)) .…”

Recent Progress on the Synthesis of Graphene-Based Nanostructures as Counter Electrodes in DSSCs Based on Iodine/Iodide Electrolytes

“…In similar works, heteroatom-doped graphene was obtained either by annealing graphene oxide in the presence of precursor substances or by pyrolysis of chemically modified graphene derivatives. In the former case, typical precursors include triphenylphosphine (P-doped material) [30], cobalt phthalocyanine (CoN x -doped material) [31], and elemental sulfur (S-doped material) [32]. In the latter case, B,N-doped graphene nanostructures were obtaining by pyrolysis of graphene oxide grafted with 1-aminopropyl-3-methylimidazolium tetrafluoroborate ionic liquid [33].…”
