原始语种摘要: Abstract(#br)Rational designs of photocatalysts with high activity and stability in redox reactions have been an imperative requirement for practical applications. Herein, a hetero-structured photocatalyst, namely Mn 0.25 Cd 0.75 S/WO 3 , has been synthesized via an in-situ growth. This hybrid material presents a significantly improvement for hydrogen evolution and stability with respect to the Mn 0.25 Cd 0.75 S sample. These improvements can be attributed to the formation of a direct Z-scheme, and this formation has been confirmed by the photoluminescence (PL) detection of hydroxyl radicals trapping and charge flow tracking by photo-deposition of Pt and PbO 2 nanoparticles. A few measurements reveal that the charge transfer mechanism of the Z-scheme leads efficiently spatial separation...
