Ultra-stable Bi4O5Br2/Bi2S3 n-p heterojunctions induced simultaneous generation of radicals OH and O2− and NO conversion to nitrate/nitrite species with high selectivity under visible light

In situ construction of a C3N5 nanosheet/Bi2WO6 nanodot S-scheme heterojunction with enhanced structural defects for the efficient photocatalytic removal of tetracycline and Cr(vi)

“…Generally, a larger arc radius corresponds to a greater inherent resistance. [77][78][79][80][81][82][83] Excitingly, 10CN/BWO shows the smallest arc radius among the samples, showing that 10CN/BWO has the lowest charge-transfer resistance, greatly boosting its efficient charge separation.…”

Enhancing Green Product Generation of Photocatalytic NO Oxidation: A Case of WO3 Nanoplate/g-C3N4 S-Scheme Heterojunction

“…The NO 3 – selectivity ratio of WO 3 /g-C 3 N 4 is significantly different and much higher compared to the pure materials under visible irradiation, which is about 10.63. This result is explained by the existence of oxygen defects in WO 3 materials, which are easily formed by the hydrothermal synthesis method, supplying many NO 2 adsorption sites for the NO 3 – conversion. − This result also proved that WO 3 /g-C 3 N 4 is the most optimal and efficient besides significantly improving the photocatalytic ability for NO removal and decreasing the NO-to-NO 2 conversion yield drastically.…”

Novel Z‐scheme 2D/2D Bi4O5Br2/BiOCl heterojunction with enhanced photocatalytic activity for RhB degradation

“…The O 1 s asymmetric signal of Bi 4 O 5 Br 2 in Fig. 5(b) was deconvoluted into two peaks located at about 529.9 and 530.8 eV which corresponded to BiO bonds and oxygen‐containing species adsorbed on surface, respectively 43 . In comparison with Bi 4 O 5 Br 2 , the Br 3d 5/2 and 3d 3/2 peaks of BC2 shifted from 68.7 and 69.8 eV to higher 68.8 and 69.9 eV, may due to the decreased electron cloud density of Bi 4 O 5 Br 2 after contact with BiOCl 44,45 .…”
