Simultaneous hydrogen production and pollutant degradation by photocatalysis of wastewater using liquid phase plasma

Ethanolamine released from a nuclear power plant was degraded by photocatalytic decomposition using plasma in the liquid phase with metal-incorporated photocatalysts. Metal-incorporated titanium dioxide photocatalysts were employed with carbon nanotubes and carbon nanofibers as a support. The photocatalytic decomposition of ethanol amine-contained water induced the degradation of ethanolamine and H₂ evolution, simultaneously. The degradation of ethanolamine and H₂ evolution were elevated by incorporating Ni on titanium dioxide nanocrystallites. The rate of H₂ evolution in the ethanolamine-containing water was higher than that in pure water, which was attributed to the additional H₂ evolution by the photodecomposition of ethanolamine in water.
