| Abstract:Current research of photocatalytic hydrogen production mainly focused on modification of semiconductor materials for improving their photocatalytic hydrogen production performance. It was well known that in the process of decomposing water to produce hydrogen, methanol was added as a sacrificial agent to consume photogenerated holes. Therefore, it could be seen that sacrificial agent should also be a very important factor affecting the hydrogen production performance of semiconductor photocatalysts. Xylooligosaccharide was chosen as sacrificial agent and compared with the common used sacrificial agent methanol in photocatalytic hydrogen production performance. The results showed that no hydrogen was detected in photocatalytic hydrogen production by semiconductor materials TiO2 and C3N4 without Pt loading. Semiconductor materials TiO2 and C3N4 loading 1 wt% precious metal Pt i.e Pt-TiO2 and Pt-C3N4 could be used as photocatalysts for hydrogen production based on catalyst mass, 4298.3 μmol/g and 356.5 μmol/g hydrogen were produced respectively with methanol as sacrificial agent after 24 h photocatalytic reaction, 3054.5 μmol/g and 495.6 μmol/g hydrogen were produced respectively after 24 h photocatalytic reaction using xylooligosaccharide as sacrificial agent. The reacts indicated that xylooligosaccharide could be used as sacrificial agent for photocatalytic hydrogen production, especially for Pt-C3N4, its hydrogen production performance was better than that of methanol. |
