Synthesis and characterization of BiOI/BiOBr heterostructure films with enhanced visible light photocatalytic activity

Solvothermal synthesis of CdS QDs/MWCNTs nanocomposites with high efficient photocatalytic activity under visible light irradiation

“…Fig. 6a shows the temporal changes in To quantify the photocatalytic abilities of as-prepared samples and understand the reaction kinetics of MG degradation, the apparent pseudo-first-order model, ln(C 0 /C t ) =k app t, is applied, where t is the irradiation time and k app is the rate constant [35]. …”

Microwave-Assisted Synthesis of BiOCl/BiOBr Composites with Improved Visible-Light Photocatalytic Activity

“…The autoclave was then heated at 140 •C for 8 h and cooled down to room temperature. 5 The final product was separated as the above steps. The as-prepared samples were used for further characterizations.…”

“…[1][2][3][4] As a traditional photocatalyst, TiO 2 can be activated by UV irradiation ( λ < 390 nm). 5 However, its efficiency in solar energy conversion is limited by its large band gap (3.2 eV). [1][2][3][4][5][6] So far, composite photocatalysts may be more photocatalytically active than a single photocatalyst, as they can reduce the recombination and enhance the separation of electron-hole pairs.…”

A novel Bi-based oxybromide SrBiO2Br: Synthesis, optical property and photocatalytic activity

“…As a new family of promising photocatalysts, Bi-based ternary compounds, such as BiOX (X¼Cl, Br, I) [9][10], Bi 2 MoO 6 [11,12], Bi 2 WO 6 [13][14][15], and BiVO 4 [16] have demonstrated remarkable photocatalytic activities owing to their uniquely layered structures with an internal static electric field perpendicular to each layer, which can effectively promote the separation of photogenerated electron-hole pairs, and thus exhibit a high photocatalytic performance [17]. Recently, Bi-based quaternary compounds have been investigated and show good photocatalytic ability under UV and visible light irradiation for the degradation of organic dyes solution, such as PbBiO 2 Br [18], CdBiO 2 Cl [19], Bi 4 NbO 8 Cl [20] and PbBiO 2 Cl [21].…”
