Bandgap engineering approach for designing CuO/Mn3O4/CeO2 heterojunction as a novel photocatalyst for AOP-assisted degradation of Malachite green dye

“…These peaks were coherent with the monoclinic system with an end-centered lattice structure of CuO nanomaterial, as well as the results matched with the previously reported literature (JCPDS 89–5899) presenting the cell parameters of the monoclinic CuO with the space group of Cc 9 , are a = 4.689 Å, b = 3.420 Å, c = 5.130 Å, and β = 99.57° 38 , 39 . Peaks were observed at 2Ɵ values of 18.01°, 28.9°, 31.0°, 32.3°, 36.1°, 44.4°, 58.5°, and 63.2° corresponding to diffraction planes of (101), (112), (200), (103), (211), (220), (321), and (116), respectively and these peaks were consistent with the tetragonal system with body-centered lattice structure of Mn 3 O 4 nanomaterial, and the data best fit with the earlier reported JCPDS file number 89–4837 40 , 41 . With the space group of I41/amd [141], the cell parameters of the tetragonal Mn 3 O 4 are a = 5.763 Å and c = 9.…”

Construction of a hydrangea-like Bi2WO6/BiOCl composite as a high-performance photocatalyst

“…3b-e 002), ( 101), ( 110), ( 102), ( 003), ( 112), ( 200), (113), (211), ( 212) and (214) planes of highly crystalline BiOCl (JCPDS No. 06-0249), 36,37 respectively. In the patterns of the Bi 2 WO 6 /BiOCl-1/1, Bi 2 WO 6 /BiOCl-1/2 and Bi 2 WO 6 /BiOCl-2/1 composites, the diffraction peaks are a combination of characteristic peaks of Bi 2 WO 6 and BiOCl.…”

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

“…According to previous research, BiOCl-based photocatalysts can be divided into three main categories: metal/BiOCl, semiconductor/BiOCl, and carbon/BiOCl heterogeneous structures. − ,,,,− ...…”

“…The synthesis of type-II and Z-scheme junctions in metal oxide (sulfide)/BiOCl systems is a promising method to acquire higher photocatalytic performances, which provides a better opportunity to understand the transfer pathways of photoinduced charge carriers and further reveals the photocatalytic mechanisms. In recent years, the controllable synthesis of metal oxide (sulfide)/BiOCl and other oxysalts/BiOCl photocatalysts has been extensively reported, and the relationships between structure and property as well as performance of products have also been amply elucidated. − …”

“…Additionally, other single metal oxide/BiOCl composites were investigated in recent years, such as Fe x O y /BiOCl, − ZnO/BiOCl, , TiC/PDMS/ZnO/BiOCl, WO 3 /BiOCl, ,, CuO/BiOCl, Cu 2 O/BiOCl, Mn 3 O 4 /BiOCl, CeO 2 /BiOCl, − SiO 2 /BiOCl, − Al 2 O 3 /BiOCl, MoO 2 /BiOCl, Co 3 O 4 /BiOCl, In 2 O 3 /BiOCl, and NiO/BiOCl …”
