Effect of plasmonic au nanoparticles on the photoactivity of polyaniline/indium tin oxide electrodes for water splitting

Abstract: Three nanomaterials based on polyaniline (PANI) are prepared on indium tin oxide (ITO) and applied as electrodes for H2 generation due to the water‐splitting process. PANI/ITO films are prepared using oxidation polymerization method at 25°C, then coated with Au nanoparticles with different thicknesses (sputter time from 1 to 2 min). The three prepared electrodes; PANI/ITO (Electrode (0), 1‐min‐Au/PANI/ITO (Electrode (I)), and 2‐min‐Au/PANI/ITO (Electrode (II)) are compared for H2 generation from H2O. Scanning … Show more

“…Besides, most of the absorbed irradiation by the prepared nanostructured electrode from the artificial visible light generates a high density of electron-hole pairs, this matches our recently published literature. [47][48][49] The high value of the produced photocurrent density is an important indicator for successful PEC water splitting under 400 W halide lamp illumination.…”

“…The obtained results are also presented in Bode plots ( Figure 11 b,c). The Nyquist plot of 3.0% Ni-doped SnO 2 :Ir photoelectrode shows that there is a small semicircle with a small diameter in the high-f side, indicating the redox reaction [ 66 ], followed by a linear stage covering the region of middle/low fs. These PEC-IS spectra displayed mixed diffusion/kinetic controlled routes.…”

“…After Au coating, the J ph value becomes stable at about 0.07 mA·cm −2 , Figure 9 b. These values indicate the TiN and Au coating materials have high stability and anticorrosion properties that maintain the produced J ph at the same values with time [ 13 , 61 ]. This means that every small change in the produced J ph value refers to a small corrosion reaction due to the acidity of the sewage water.…”

“…The most used plasmonic materials are noble metals, such as Au, Ru, Rh, and Pt, but these metals are very expensive [ 12 ]. Rabia et al used Au to enhance the water-splitting reaction for H 2 production under light [ 13 ]. Shi et al used Pt to enhance the activity of CdS materials for water splitting, in which the photoactivity is enhanced very much by using Pt metal [ 14 ].…”
