Abstract
Facile construction of Ag, In2O3, or Nd2O3 nanoparticles (NPs) incorporated mesoporous LaNaTaO3 nanocrystalline using Pluronic F-127 were explored for photocatalytic H-2 generation compared to pristine LaNaTaO3 nanocrystalline. The mesoporous LaNaTaO3 was achieved a little H-2 generation similar to 40 mu molg(-1); however, H-2 generation extremely promotes with the incorporation of Ag, In2O3, and Nd2O3 NPs compared to pristine LaNaTaO3. The yield of the H-2 generation of Ag/LaNaTaO3 photocatalyst was greater 75 times than pristine LaNaTaO3. A maximum H-2 generation-1755, 2281.5, and 2965.9 mu molg(-1) was achieved for Nd2O3, In2O3, or Ag/LaNaTaO3 photocatalysts, respectively. The H-2 generation rate for Ag/LaNaTaO3 photocatalyst was calculated to be 329.5 mu molg(-1)h(-1), 110 times greater than that of pristine LaNaTaO3 (3 mu molg(-1)h(-1)). The H-2 generation rate of Ag/LaNaTaO3 photocatalyst was faster 1.7 and 1.3 times than that either Nd2O3 or In2O3/LaNaTaO3 photocatalysts, respectively, indicating the highly promoted photocatalytic H-2 generation of Ag/LaNaTaO3 photocatalyst. The impact of Ag, In2O3, or Nd2O3 NPs on the morphology, crystal structure, optical, photoelectrochemical, photoluminescence measurement of mesoporous LaNaTaO3 nanocrystalline, and their H-2 generation in the existence aqueous glycerol solution were studied in detail.
