Enhanced Visible‐light Photocatalytic Dye Degradation Ability of CdS/O‐CNTs Nanocomposites

Abstract

The rapid developpment of industrialization and urbanization has caused extensive environmental pollution, especially water pollution. Here, a bud-like shaped CdS (cadmium sulfide), with O-CNTs (oxidized multiwalled carbon nanotubes) homogeneously embedde (BCO), were synthesized by a facile hydrothermal process. The surface properties of the composites and the photocatalytic performances were studied systematically. The photocatalytic degrading anionic dye Methyl orange (MO) and cationic dye Rhodamine B (RhB) under visible light (λ � 420 nm) unveiled that BCO nanocomposites exhibited much better photocatalytic decolorization activity than bud-like shaped CdS. Due to the delaying time of electron recombination to the hole and the participation of holes (h + ) and * superoxide radicals ( * O 2 À ) by loading O-CNTs, BCO-3 wt% could decolorize 98.5 % RhB in 30 min and 95.5 % MO in 90 min, implying potential applications prospect.
