“…The chemical structures and lattice planes of BiOBr and CLB x were determined by X‐ray diffraction. As shown in Figure 1, the detection peaks of all samples can be well matched with BiOBr (JCPDS 09‐0393) [29,30] . The diffraction peaks at 10.9, 21.9, 25.2, 31.7, 32.2, 57.2 and 76.8° belong to (001), (002), (101), (102), (110), (212) and (310) lattice planes, respectively.…”

Photocatalysis is a green technology with important application prospects in environmental fields such as wastewater treatment. Here, we synthesized chrysanthemum‐like BiOBr microspheres (CLB0.45) under introduction of structure guide and soft‐template. Natural biomass chitosan (CS) in the precursor of BiOBr successfully suppressed the growth of both (001) and (102) lattice planes through solvent effect, and promote the expose of (110) lattice planes that dominated the photocatalytic performance. Significantly, the polymer chains regulated the nanosheets of BiOBr to accurately self‐assemble. The obtained CLB0.45 had narrower band gap and more active sites due to surface defects, and the photocatalysts have higher photo‐electron hole pairs separation efficiency. And the degradation performance towards RhB (99.7%, 30 min) of the CLB0.45 was increased, which was 4.6 times higher than that of pure BiOBr. The degradation rate of tetracycline (TC) also exhibited excellent (85.3%). The photodegradation mechanism of CLB0.45 was proposed and verified. In summary, the prepared CLB0.45 through structure guiding and soft‐template have a promising future in the photocatalytic purification of organic pollutants.

“…29 The peaks at 1460 and 1350 cm −1 are related to the C–N mode in the trace CTAB. 30 The PbMoO 4 sample's FT-IR spectrum shows a broad peak at 3400 cm −1 that is related to the O–H stretching vibration of adsorbed water. 31 A slight peak vibration at 1384 cm −1 was observed, which was related to the vibration mode of the Mo–OH bond.…”

Without any chemical agent, gold nanosheets (AuNSs) were controllable synthesized through a facile photo-induced reduction within bacterial cellulose (BC) biopolymers. Compared with traditional polymers, AuNSs modified BC biopolymers (AuNSs@BC) biopolymers exhibited similar levels of softness, ductility, and better tensile strength. The in situ constructing of AuNSs@BC biopolymers was demonstrated to provide great reusability and antibacterial activities and towards both of Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) . The optimized AuNSs@BC biopolymers remain at least 95% antibacterial activities after three cycles. The facile and shape-controlled synthesis of AuNSs@BC biopolymers is believed to be useful for the design and application of biomass-based medical dressing.
