Abstract

A novel visible-light responsive layered perovskite photocatalyst Bi4MO8X (M = Nb, Ta; X = Cl, Br) has been successfully constructed using BiOX (X = Cl, Br) via a solid state method.

A review on photocatalysis in antibiotic wastewater: Pollutant degradation and hydrogen production

“…Past years have witnessed the development of the bismuth-based materials for photocatalytic hydrogen evolution and pollutants degradation [33,34]. Different from the mentioned three main kinds of photocatalysts, bismuth-based materials, such as BiVO4, Bi2O3, have suitable valence band position for visible-light-driven antibiotics degradation.…”

Sonochemical Hydrogen Production as a Potential Interference in Light-Driven Hydrogen Evolution Catalysis

“… 10 , 24 Note that this sonolytic hydrogen evolution capacity is different to photochemical HER formation depending on different types of alcohol, where completely different orders of reactivity were reported. 20 , 21 This could of course lead to dramatic changes in data interpretation depending on the expected versus real mechanism of HER.…”

Facet Coupling Design for Bi4TaO8Cl/g‐C3N4 via Electrostatic Self‐Assembly to Enhance Photocatalytic Activity

“…Moreover, no extra peaks can be detected in CNBi-X and CNBi-2N catalysts, implying that there is no impurity after ball milling treatment. [17] From the patterns, we can see that the phase of g-C 3 N 4 in CNBi-X cannot be well detected, which is because g-C 3 N 4 possesses low diffraction intensity and the peaks of two catalysts overlap. Furthermore, the diffraction peak of CNBi-X at 29.8°shifts to small angle (Figure 3c), manifesting that a tight interfacial connection is established.…”

“…The first two peaks represent the adsorbed H 2 O on surface and CÀ O (C=O) bonds of g-C 3 N 4 , and the last one is owing to the existence of crystal lattice oxygen of Bi 4 TaO 8 Cl. [17,24] The N 1s spectrum (Figure S7b) displays three deconvolution peaks, including: (1) CÀ N=C bond at 398.6 eV, (2) the bridging N at 399.7 eV, and (3) CÀ NÀ H bond at 401.1 eV. [25] The Cl spectrum (Figure S7c) exhibits two classical peaks at 199.5 (Cl 2p 3/2 ) and 197.9 eV (Cl 2p 1/2 ).…”
