Photoelectrochemical reforming of biomass for hydrogen generation†
Abstract
In this communication, photoelectrochemical (PEC) reforming of glucose was accomplished on hierarchical TiO2 nanotube arrays (TiO2 NTs). The presence of glucose significantly enhanced the PEC performance of TiO2 NTs, due to a negative shift of the onset potential and a lengthening of the electron lifetime, thus reducing the recombination of photogenerated electrons and holes.
