Hydrogen production under visible light by photocatalytic reforming of glucose over an oxide solid solution photocatalyst

Hydrogen production under visible light by photocatalytic reforming of glucose over an oxide solid solution photocatalyst BIx Y1-xVO4 (BYV) was demonstrated for the first time It was found that a certain amount of Y doping would promote the transition of BIVO4 from monoclinic to tetragonal phase and finally lead to the formation of tetragonal BYV solid solution BYV with a B/Y ratio of 11 showed the highest activity for hydrogen production The amount of photoproduced hydrogen lowered after several hours of reaction However when the gas product was replaced with N-2 atmosphere hydrogen production recovered It is supposed that the generated CO2 might participate in the redox reaction and in some way inhibit the hydrogen production Therefore for photocatalylic reforming of glucose removal of gas product in time is indispensable (C) 2010 Elsevier BV All rights reserved
