Semiconductor electrodes. 40. Photoassisted hydrogen evolution at poly(benzyl viologen)-coated p-type silicon electrodes
Poly(benzy1 viologen) (PBV) shows two reduction waves in aqueous (at -0.37 and -0.88 V vs. SSCE) or N,Ndimethylformamide (at -0.22 and -0.64 V vs. SSCE) solutions. A film of PBV on the surface of a p-type silicon electrode can be photoreduced at more positive potentials. When metallic Pt is incorporated into the film, the photoproduction of hydrogen occurs with an underpotential of ca. 0.4 V. T...
متن کاملElectrochemical synthesis of NieS/CeO2 composite electrodes for hydrogen evolution reaction
NieS/CeO2 electrodes have been prepared by a composite electrodeposition technique using nickel sulfaminate bath containing suspended microor nano-sized CeO2 particles. The composite electrodes exhibit a high activity for the hydrogen evolution reaction (HER) in alkaline solutions, most likely due to the synergistic effects between Ni and CeO2, as well as the increased surface area of the elect...
متن کاملThe Theory of the Light-Induced Evolution of Hydrogen at Semiconductor Electrodes
The photoelectrode kinetics of the hydrogen evolution reaction is considered, using the WKB approximation for the penetra t ion of the barr ier at the semiconductor-solut ion interface. The absorption characteristics of photons in the eIectrode are introduced and the n u m b e r of electrons produced at the surface is obtained as a function of the semiconductor statistics, and also diffusion an...
متن کاملApplication of Pd-Substituted Ni-Al Layered Double Hydroxides for the Hydrogen Evolution Reaction
Clean production of hydrogen from electrochemical water splitting has been known as a green method of fuel production. In this work, electrocatalytic hydrogen evolution reaction (HER) was investigated at new prepared layered double hydroxides (LDH) in acidic solution. NiAl/carbon black (CB) LDH was monitored using x-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, scannin...
متن کاملPreparation of Ni-P-CeO2 electrode and study on electrocatalytic properties for hydrogen evolution reaction
In this study ternary Ni-P-CeO2 catalysts were first synthesized by the Co-electrodeposition method on a copper substrate and then characterized by means of microstructural and electrochemical techniques toward a hydrogen evolution reaction (HER). Also, for comparison other catalysts such as Ni-CeO2, Ni-P, and Ni were prepared and characterized by the same methods. The microstructure of the inv...
