Assessing the feasibility of reduced graphene oxide as an electronic promoter for photocatalytic hydrogen production over Nb-Ta perovskite photocatalysts

Visible-light photocatalytic hydrogen production in a narrow-bandgap semiconducting La/Ni-modified KNbO3 ferroelectric and further enhancement via high-field poling

“…By comparison (Fig. 1f), [9][10][11][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] the visible-light PHE rate of the poled semiconducting La/Ni-modied KNbO 3 ferroelectrics was superior to that of most perovskite ferroelectric oxides, such as KNbO 3based, BaTiO 3 -based and PbTiO 3 -based ferroelectric photocatalysts. These results provide a reference for further investigating high-performance ferroelectric-based oxide photocatalytic materials.…”

Interconnected Periodic Macroporous NaNbO3 for High-Efficiency Solar-Driven Photocatalytic Hydrogen Evolution

“…Perovskite niobates, particularly NaNbO 3 , have emerged as highly promising candidates for photocatalysts due to their cost-effectiveness, excellent chemical stability, and environmentally friendly characteristics. − However, their photocatalytic performance is hindered by insufficient light absorption, low specific surface area, and pronounced electron–hole recombination. Consequently, diverse modification strategies such as morphological control, , heteroatom doping, , and heterojunction construction , have been employed to enhance the photocatalytic activity for hydrogen generation.…”

Spectroscopic Analyses of Changes in Photocatalytic and Catalytic Activities of Mn- and Ni-Ion Doped and Base-Treated Reduced Graphene Oxide

“…New catalysts based on rGO supports are being used widely in redox reactions [18][19][20][21][22]. In particular, rGO is being employed for photocatalytic degradation (PCD) in advanced reaction processes such as those involved in fuel cells and photosensors because of its low cost [23][24][25][26][27].…”
