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 <img border="0" alt="radical dot" data-inlimg="/entities/rad" src="/sd/grey_pxl.gif" class="glyphImg imgLazyJSB">OH oxidation process.
