Photoelectrochemical water splitting: silicon photocathodes for hydrogen evolution
The development of low cost, scalable, renewable energy technologies is one of today’s most pressing scientific challenges. We report on progress towards the development of a photoelectrochemical water-splitting system that will use sunlight and water as the inputs to produce renewable hydrogen with oxygen as a by-product. This system is based on the design principle of incorporating two separa...
متن کاملSilicon Nanowire Photocathodes for Photoelectrochemical Hydrogen Production
The performance of silicon for water oxidation and hydrogen production can be improved by exploiting the antireflective properties of nanostructured silicon substrates. In this work, silicon nanowires were fabricated by metal-assisted electroless etching of silicon. An enhanced photocurrent density of -17 mA/cm² was observed for the silicon nanowires coated with an iron sulphur carbonyl catalys...
متن کاملHydrogen evolution from Pt/Ru-coated p-type WSe2 photocathodes.
Crystalline p-type WSe(2) has been grown by a chemical vapor transport method. After deposition of noble metal catalysts, p-WSe(2) photocathodes exhibited thermodynamically based photoelectrode energy-conversion efficiencies of >7% for the hydrogen evolution reaction under mildly acidic conditions, and were stable under cathodic conditions for at least 2 h in acidic as well as in alkaline elect...
متن کاملSilicon nanowire arrays coupled with cobalt phosphide spheres as low-cost photocathodes for efficient solar hydrogen evolution.
We demonstrate the first example of silicon nanowire array photocathodes coupled with hollow spheres of the emerging earth-abundant cobalt phosphide catalysts. Compared to bare silicon nanowire arrays, the hybrid electrodes exhibit significantly improved photoelectrochemical performance toward the solar-driven H2 evolution reaction.
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...
