«Since the
photoelectrochemical cell is built for the purpose of hydrogen production and HMF oxidation simply replaces
oxygen production at the anode, in essence, no resources are
used specifically for HMF oxidation,» says Choi.
These include electrolysis, which
uses electricity to split water into hydrogen and
oxygen, and
photoelectrochemical (PEC) cells, which
use sunlight to do the same thing.
