Plasmonically enhanced hydrogen evolution with earth-abundant aluminum
Our paper on “Plasmonically enhanced hydrogen evolution with an Al-TiO2-based photoelectrode” has been published in J. Phys. Chem. C. as part of a virtual special issue “Honoring Michael R. Berman”.
In this work, we demonstrate a n-TiO2/aluminum (Al) nanodisk/p-GaN sandwiched photoelectrode architecture that efficiently exploits the hot carrier generation in Al nanodisks and the plasmonic near-field enhancement to drive H2 evolution in neutral aqueous solution with the photoelectrode performance being on par or better than previous reports of plasmonic photoelectrodes using Au nanoparticles in combination with cocatalyst species.
