“…As a special nanoarchitecture, the 3DOM structure is a promising candidate for improving the gas sensing properties of materials. The 3DOM structure serves a large surface area owing to its porosity structure [21], which can improve gas sensitivity of material [22,23]. Besides, gas diffusing can beneficiate from the ordered macroporous structure, which can improve sensing property via decreasing response and recovery times [24].…”

“…The first one is to synthesize pure BiOBr with various architectures, such as lamellas, hierarchical microspheres, microflowers, mesoporous microspheres, and self-assembled 3-D architectures [10][11][12][13][14]. Another alternative is relevant to the fabrication of BiOBr hybrids with other semiconductors of suitable energy-band structures and the obtained hybrids normally own unique optical and catalytic properties, thanking to the formation of a positive synergistic effect between these ingredients [15][16][17][18][19].…”

a b s t r a c tExfoliated g-C 3 N 4 (CNs)-BiOBr hybrids with heterojunction structure was fabricated through a chemical deposition-precipitation route. The characterization showed the uniform existence of CNs and BiOBr in hybrids. The fabricated CNs-BiOBr was of enlarged specific surface area, unique optical property, and well-matched energy-band structures. The photocatalytic performance on dye Rhodamine B (RhB) and 2,4-diclorophenol (2,4-DCP) were dramatically improved. Under identical conditions, sample 0.5CNs-BiOBr and CNs-BiOBr were identified as the best candidate, respectively, for catalytic degradation of RhB and 2,4-DCP. The former could show a reaction rate over RhB about 2.7 and 6.8 times as high as BiOBr and CNs alone, and the later exhibited a reaction rate over 2,4-DCP nearly 7.5 and 2.5 times as high as individual BiOBr and CNs. Finally, a possible catalytic mechanism was also proposed through active species trapping experiments.

“…The BET result indicates the surface area for GZnO is 13.2 m 2 g À 1 , much larger than that for ZnO. Large surface area and mesoporous feature can inform more active sites and increase the contact with the dye pollutant, which should be favorable for the improved photocatalytic activity [25]. Moreover, G-ZnO exhibits higher optical absorption at UV region, mainly at the UV light emission region.…”

“…3 presents the isotherm of G-ZnO, and the corresponding pore size distribution curves are given in the inset. G-ZnO exhibits a type IV isotherm of a type H3 hysteresis loop, characteristic of mesoporous materials, according to Brunauer-DemingDeming-Teller (BDDT) classification [25]. The BET specific surface area is determined to be 13.2 m 2 g À 1 .…”
