Photoelectrochemical conversion of NO3(-) to N2 by using a photoelectrochemical cell composed of a nanoporous TiO2 film photoanode and an O2 reducing cathode.
Photoelectrochemical conversion of nitrate anions into dinitrogen was successfully achieved by using a photoelectrochemical cell composed of a nanoporous TiO2 film photoanode and an O2 reducing cathode in the presence of NH3, which can be regarded as a model of denitrification and is of importance for environmental cleaning.
