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

Abstract

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.
