Abstract:
The activity of many water‐splitting photocatalysts could be improved by the use of Rh III –Cr III mixed oxide (Rh 2− x Cr x O 3 ) particles as cocatalysts. Although further improvement of water‐splitting activity could be achieved if the size of the Rh 2− x Cr x O 3 particles was decreased further, it is difficult to load ultrafine ( 〈 2 nm) Rh 2− x Cr x O 3 particles onto a photocatalyst by using conventional loading methods. In this study, a new loading method was successfully established and was used to load Rh 2− x Cr x O 3 particles with a size of approximately 1.3 nm and a narrow size distribution onto a BaLa 4 Ti 4 O 15 photocatalyst. The obtained photocatalyst exhibited an apparent quantum yield of 16 %, which is the highest achieved for BaLa 4 Ti 4 O 15 to date. Thus, the developed loading technique of Rh 2− x Cr x O 3 particles is extremely effective at improving the activity of the water‐splitting photocatalyst BaLa 4 Ti 4 O 15 . This method is expected to be extended to other advanced water‐splitting photocatalysts to achieve higher quantum yields.
