Quantification of photocatalytic hydrogen evolution [PDF]

Physical Chemistry Chemical Physics, 2013
A new photoreactor with defined irradiation geometry was developed and tested for the water reduction reaction using carbon nitride ("C(3)N(4)") as a photocatalyst. The hydrogen evolution rate was investigated with a sun simulator (I = 1000 W m(-2)) in two different operation modes: circulation and stirring of the catalyst dispersion.
