文摘
- •
Bi2Se3 and Ni doped Bi2Se3 were synthesized by solvothermal approach.
- •
Presence of nickel was confirmed by X-ray photoelectron spectroscopy (XPS) measurement.
- •
Complete degradation of malachite green (MG) dye was achieved by Ni doped Bi2Se3 with H2O2.
- •
Remarkable photo-catalytic degradation by doped bismuth selenide has been explained.
- •
Scavenger tests show degradation of MG is mainly dominated by
OH oxidation process.
