A Brief Perspective on the Fabrication of Hierarchical Nanostructure for Solar Water Splitting Photoelectrochemical Cells

摘要

Water splitting photoelectrochemical (PEC) cells are a promising method for solar energy generation. PEC cells can generate hydrogen gas through natural sunlight by harnessing the unique electrical, optical and electrochemical properties of nanostructured metal oxides. However, careful choice of the metal oxides used must be made to ensure efficient hydrogen generation. The choice of metal oxide for PEC cells must take into account the bandgap size/position and the effect of nanostructuring on these properties. Kwon et al. from Korea have published
