Study of hydrogen production from aqueous glycerol solution on RuO 2 -loaded LaNaTaO 3 has been studied. This research aim is to investigate the influence of co-catalyst RuO 2 and glycerol as a sacrificial reagent on the photocatalytic process of hydrogen production. La-doped NaTaO 3 was prepared via sol-gel route. The RuO 2 was loaded onto the LaNaTaO 3 surface by impregnation method. The sample was characterization by Scanning Electron microscopy (SEM) and X-ray Diffractometer (XRD). From XRD spectrum shows that the La-NaTaO 3 photocatalyst has high crystallinity. The SEM analysis indicates that the size of La-NaTaO 3 photocatalyst is ranging from 100 to 250 nm without agglomeration and RuO 2 as a co-catalyst is well loaded into the La-NaTaO 3 surface. The rate of hydrogen production increased significantly with a glycerol concentration. Loading RuO 2 on La-NaTaO 3 photocatalyst is proved to increase the rate of hydrogen production of 3.2 times with the addition of glycerol as a sacrificial reagent. The highest hydrogen production activity was obtained for 0.3 wt.% ruthenium loading. The role of co-catalyst RuO 2 and glycerol as a sacrificial reagent has enhanced the performance of La-NaTaO 3 photocatalyst since both play an active role in the separation efficiency of electrons and holes and the reaction of hydrogen formation.
