Photoelectrochemical Production of Hydrogen Peroxide with TiO2 and 1,5-Di(thien-2-yl)-9,10-anthraquinone via a Selective Two-Electron Oxygen Reduction Reaction in the Two-Compartment Cell

“…The performance of PEC water oxidation is also determined by the solar-to-hydrogen (STH) conversion efficiency (η STH ). Figure S9c (blue) shows that the η STH value calculated for the photoelectrode is 0.65% for TiO 2 NRs using eq S7 …”

“…Figure S9c (blue) shows that the η STH value calculated for the photoelectrode is 0.65% for TiO 2 NRs using eq S7. 50 3.3.4. Photoelectrochemical Studies in a Two-Compartment Cell (TiO 2 ||CC/AQTh).…”

Plasma Electrolytic Oxidation of Titanium in Ni and Cu Hydroxide Suspensions towards Preparation of Electrocatalysts for Urea Oxidation

“…At the same time, the current response of the Cu sample was twice as high as observed for a similar material prepared by covering the nickel foam with TiO 2 paste [ 53 ]. However, the addition of nickel to the TiO 2 system to form the photocatalyst for urea oxidation can lead to much higher current responses, such as the 360 μA cm −2 observed at 1.965 V [ 65 ] or the 10 mA cm −2 observed at 1.58 V [ 66 ], which shows that the activity of the prepared material can still be increased.…”

Hydrogen-bonded linear chain assemblies of palladium(ii)-selenoether complexes: solid state aggregates as templates for nano-structural Pd17Se15 leading to efficient electrocatalytic activity

“…The Nyquist plots depict the chargetransfer resistance, and a variation in the semicircle width with a bias voltage demonstrates that these semicircles are connected to the electrode kinetics, meaning that the width of the semicircle changes depending on the bias voltage. 51 The kinetics of the hydrogen evolution reaction for catalyst PSNP1 nanostructures is investigated by employing potentiostatic EIS.…”

“…The Nyquist plots depict the charge-transfer resistance, and a variation in the semicircle width with a bias voltage demonstrates that these semicircles are connected to the electrode kinetics, meaning that the width of the semicircle changes depending on the bias voltage. 51 The kinetics of the hydrogen evolution reaction for catalyst PSNP1 nanostructures is investigated by employing potentiostatic EIS. The reduction in the diameter of the semicircle that occurs with changing the bias suggests that electrocatalytic processes have control over the charge transfer processes that occur during the HER.…”
