Enhanced photocatalytic activity of AgCl/BiOCl heterostructures synthesized by a one-pot combustion method

Visible-light-driven photocatalytic degradation of rhodamine B using Bi2WO6/GO deposited on polyethylene terephthalate fabric

“…It is found that the specific surface areas of pure Bi 2 WO 6 and Bi 2 WO 6 /GO particles are 51.52, 46.15, 47.15, 54.06, 48.82 and 42.44 m 2 /g, respectively. This result shows that the surface area of Bi 2 WO 6 rises and then reduces with an increase of content of GO, which contributes to adsorb more active substances and further could enhance the photocatalytic properties [35].…”

Synthesis, Functional Modifications, and Diversified Applications of Hybrid BiOCl-Based Heterogeneous Photocatalysts: A Review

“…221,222 For example, AgCl NPs decorated on the surface of BiOCl nanosheets can be synthesized through a combustion strategy, which displayed an enhanced photocatalytic activity for RhB under UV light irradiation. 222 Moreover, AgCl nanotubes modified on BiOCl nanosheets can be facilely fabricated by a hydrothermal process, which demonstrated that the controllable Ag/Bi molar ratio could adjust the band gap of BiOCl in AgCl/BiOCl composites. 223 Furthermore, Qi and coworkers have confirmed that the decoration of AgBr NPs onto the {001} surface of BiOCl can boost an effective separation of charge carriers under visible light irradiation.…”

“…As a sensitizer, AgX (X = Cl, Br, I) generally exhibits a narrow band gap and high pollutant degradation efficiency, but it is easily decomposed to form Ag NPs under visible light irradiation, which will exert a negative influence for photocatalysis . However, it has been confirmed that combining AgX with UV light-response semiconductors is an outstanding strategy for enhancing the stability of AgX. , For example, AgCl NPs decorated on the surface of BiOCl nanosheets can be synthesized through a combustion strategy, which displayed an enhanced photocatalytic activity for RhB under UV light irradiation . Moreover, AgCl nanotubes modified on BiOCl nanosheets can be facilely fabricated by a hydrothermal process, which demonstrated that the controllable Ag/Bi molar ratio could adjust the band gap of BiOCl in AgCl/BiOCl composites .…”

Novel one-pot synthesis and sensitisation of new BiOCl–Bi2S3 nanostructures from DES medium displaying high photocatalytic activity

“…Typical hydro/solvothermal based approaches require moderate to high temperatures (80-200 o C), often extended reaction times (12-24 h) and the use of specific reaction vessels. [4][5][6]9,11,14 The precipitation at room temperature, the synthesis assisted by ultrasound and the combustion methods requires subsequent calcination at 300-400 o C. 15,18,19 In order to increase the photocatalytic performance and extend the absorption to the visible range, several strategies have been used in order to improve the efficiency of semiconductor photocatalysts, for example by controlling crystal facets, doping, organic and inorganic sensitization, and preparation of hybrid structures. It has been shown that the photocatalytic activity of BiOCl depends not only on its particle dimensions but also on the crystallographic orientation of its surface.…”
