“…Previously, photoelectrochemical properties of zinc oxide (ZnO), titanium oxide (TiO 2 ) and nanodiamond (ND) with RRP3HT structures were investigated at length [26,27]. The ND-RRP3HT hybrid films showed 8 to 10 times superior photochemical properties compared to the ZnO-RRP3HT and TiO 2 -RRP3HT hybrid structures [26]. The size of ND particles is varied for ND-RRP3HT hybrid film for photoelectrochemical studies.…”

Recently, we have studied photoelectrochemical properties of films of nanodiamond (ND)regioregular polyhexylthiophene (RRP3HT), ND-poly(3-dodecylthiophene), polyaniline, and other derivatives of polythiophene. The ND-RRP3HT, BN-RRP3HT and microdiamond (MD)-RRPHTH films were characterized using ultraviolet-visible spectroscopy, Fourier transform infrared spectroscopy, scanning electron microscopy, Raman spectroscopy and x-ray diffraction techniques, respectively. The short circuit current, fill factor, and power conversion efficiency (PCE) for MD-RRP3HT, ND-RRP3HT and hexagonal boron nitride (hBN)-RRP3HT films were compared. The ND-RRP3HT nanostructured film revealed 8 to 20 times more photocurrent than most other nanostructured RRP3HT films in a photoelectrochemical cell. The ND-RRP3HT and hBN-RRP3HT films revealed improved efficiency compared to the MD-RRP3HT film. Due to the increased band gap, the hBN-RRP3HT have a higher PCE than ND as well as MD films. ND-RRP3HT and hBN-RRP3HT hybrid films exhibited comparable photoelectrochemical properties.

“…The colloidal α-Fe 2 O 3 -TiO 2 materials were used to coat on ITO glasses (2cm ×2.5 cm) and were cured at 100 °C for an hour. The counter electrode was fabricated by immersing pieces of Si-wafer in RRPHTh-ND colloidal solution [19].…”

Recently, photoelectrochemical (PEC) water splitting using semiconductor photoanode has received great attention due production of hydrogen through clean energy. The alpha hematite (α Fe 2 O 3 ) is one of the candidate amongst photoanodic materials, which is chemically stable, abundant in nature with a band gap of 2.0-2. 2eV allowing to be harvesting in the visible light. However, it has also drawn back due to high recombination rate of electron-hole pair revealing the low concentration of charges and lower device performance. In common with α-Fe 2 O 3 , the titanium dioxide (TiO 2 ) has been known as one of the most explored photoanode electrode material due to its physical and chemical stability in aqueous and non-toxicity. However, TiO 2 has large bandgap (3.0-3.2 eV) that results in absorbing UV light and very small part of visible region. Incorporation of TiO 2 in α-Fe 2 O 3 could achieve better efficiencies as photoanode materials by enhancing the electric conductivity, limited hole diffusion length, and both materials can absorb light in both UV and visible spectrum range. However, the photoanodic properties of α-Fe 2 O 3 with different concentrations of TiO 2 are mostly unknown. Under this work, -Fe 2 O 3 -TiO 2 nanomaterial was synthesized using a hydrothermal method. The -Fe 2 O 3 -TiO 2 nanomaterials containing different weight percentage (2.5, 5, 16, 25, and 50) of TiO 2 to -Fe 2 O 3 were characterized using SEM, XRD, UV-Vis, FTIR and Raman techniques, respectively.

Supramolecular composites composed of fullerene C60 and carbon nanodiamond (ND) were constructed through spontaneous complexation of C60 aggregates onto the surface of ND aggregates in N‐methylpyrrolidone (NMP). The resulting C60‐ND composite was assembled onto a nanostructured SnO2 electrode by an electrophoretic deposition method. Formation of the C60‐ND composite was confirmed by dynamic light scattering (DLS) and field‐emission scanning electron microscopy (FESEM). The C60‐ND composite on the SnO2 electrode showed high incident photon‐to‐current efficiencies (IPCEs) in the visible region as compared with the single component system of C60 or ND. The improved photocurrent generation of the C60‐ND composite may result from the photoinduced charge separation at the interface between C60 and ND. These results obtained here will provide valuable information on the design of optoelectronic devices based on all‐nanocarbon materials.
