B-Doped Cbo Solid Solution: Synthesis, Characterization, and Their Application in Water Splitting

A series of boron -doped cerium - bismuth oxide (CBO) solid solutions were fabricated by combustion method by using unimolecular mixture of nitrides of cerium and bismuth in presence of fuel i.e., urea at low temperature 300 C-degrees. The combustion product possesses Bi3+ ion and Ce3+ and crystallized in a fluorite FCC phase . As-produced fine yellow powder crystallize in almost 13-32 nm size needle -shape particle, clustered in cotton-wool form. The photocatalytic water splitting activity was observed for the entire B -doped CBO series and the maximum hydrogen production was observed for 8 % B -doped CBO sample i.e. 332.43 mu mol g(-1) h(-1).
