The most efficient solar hydrogen production schemes, which couple solar cells to electrolysis systems, reach solar-to-hydrogen (STH) energy conversion efficiencies of 30% at a laboratory scale3. Photocatalytic water splitting reaches notably lower conversion efficiencies of only around 1%, but the ...
Carlsson , Kazunari Domen * and Markus Antonietti The production of hydrogen from water using a catalyst and solar energy is an ideal future energy source, independent of fossil reserves. For an economical use of water and solar energy, catalysts that are sufficiently efficient, stable, ...

Hydrogen production through water electrolysis is of considerable interest for converting the intermittent electricity generated by renewable energy sources into storable chemical energy, but the typical water electrolysis process requires a high working voltage (>1.23 V) and produces oxygen at the anod...
All the samples with Mo additive exhibited a better redox performance than those without Mo, and the Mo–Zr additive in iron oxide was the best effective one enhancing hydrogen production from water decomposition. For Fe2O3–Mo–Zr, the average H2 production temperature could be significantly ...
