UV light-activated decomposition/cleaning of concentrated biomass wastes involving also solid suspensions with remarkably high quantum efficiency

Abstract UV light-activated decomposition/cleaning of high concentration (>10 3 –10 4  ppm) biomass model and wastes in water involving also solid suspensions into CO 2 and N 2 were achieved by using a specially designed biophotochemical cell (BPCC) comprising a nanoporous semiconductor (TiO 2 ) film photoanode/an O 2 -reducing cathode unit and a large volume bulk aqueous phase with a remarkably high internal quantum efficiency over 80 (=8000%) for pig urine.
