A facile template-free synthesis of Bi₂Sn₂O₇ with flower-like hierarchical architecture for enhanced visible-light photocatalytic activity

Abstract

<p>A novel flower-like structure of Bi₂Sn₂O₇ was synthesized by a facile hydrothermal method which showed enhanced photodegradation of tetracycline.</p>

Preparation of Ag3PO4tetrapods anchored to nitrogen-doped carbon quantum dots for enhanced photocatalytic performance

“…6(d) and Table S1 (ESI†), the time-resolved transient fluorescence plots demonstrate that the separation efficiency of photo-generated carriers has been strengthened. The triple exponential decay kinetics were fitted by the following function: 49 where B is constant, A 1 , A 2 , and A 3 are amplitudes, τ 1 , τ 2 , and τ 3 are radiations. The NCQDs(0.75%)/Ag 3 PO 4 photocatalytic sample with a higher τ value (4.59 ns) increases the fluorescence lifetime and improves the separation efficiency of electron–hole pairs, which ultimately enhances the photocatalytic property.…”
