“…According to above points, boric acid functional composites based on magnetic chitosan can be used as adsorbent, offering efficient enrichment and separation of shikimic acid via boronate affinity technique. Moreover, boric acid groups are capable of enhancing the recognition and adsorption selectivity towards the target when compared with hydroquinone and p‐Nitrophenol and other analogues without cis‐diol structure.…”

Recently, shikimic acid (SA) has aroused great concern as the starting raw material for the synthesis of antiviral drug (Tamiflu) against the spread of influenza virus in the body. In this work, magnetic chitosan composite modified with boric acid and its application in SA recognition and separation was described. Chitosan (CT) with plenty of hydroxyl and amino groups was first coated on the surface of magnetic core Fe3O4, then carboxylic groups were grafted to the surface of Fe3O4@CT via anhydride modification, followed by the introduction of 3‐aminophenylboronic acid (APBA). The uniform morphology and composition analysis of the adsorbent (Fe3O4@CT‐COOH‐BA) were characterized by FT‐IR, XRD, XPS, SEM, TEM and UV–visible spectroscopy. The adsorption capacity of as‐prepared material was explored in detail by batch mode experiments. The adsorption kinetics fitted well with a pseudo‐second order model, and the adsorption isotherms was well described by the Langmuir model with a maximum adsorption capacity of 23.8 mg g−1 at 25 °C. Solution pH plays a crucial role in adsorption process and the optimized pH was 8.0. In addition, Fe3O4@CT‐COOH‐BA could be easily reused through an external magnet and the adsorption capacity reduced by only 4% after five adsorption–desorption cycles. These results prove that boric acid modified magnetic chitosan composite is an effective and practical adsorbent for specific recognition and selective adsorption of cis‐diol‐containing compounds.

“…Moreover, the g‐C 3 N 4 contents of g‐C 3 N 4 /Bi 2 WO 6 nanocomposites synthesized with grind‐calcination method are closer to the initial value than those from solvothermal method. Moreover, the stability of g‐C 3 N 4 /Bi 2 WO 6 nanocomposites can be confirmed with the similar modified microstructures with XRD and the following TEM . The microstructures of g‐C 3 N 4 nanosheets, Bi 2 WO 6 nanoparticles and g‐C 3 N 4 /Bi 2 WO 6 nanocomposites were characterized by TEM in Figure .…”

Photocatalytic g‐C3N4/Bi2WO6 nanocomposites were synthesized by solvothermal method and grind‐calcination method, and then the phases, microstructure, components and photodegradation to ciprofloxacin (CIP) were studied in detail. The surface area of g‐C3N4/Bi2WO6 nanocomposites decreases with the increasing g‐C3N4 content. Bi2WO6 nanoparticles prepared with solvothermal method present the smaller grain size and the higher effective interface with the similar components. The photocatalytic activity of g‐C3N4/Bi2WO6 nanocomposites is higher than those of pristine g‐C3N4 nanosheets and Bi2WO6 nanoparticles, which the optimized CIP removal percent reaches about 98% in 120 min under visible light irradiation. The Z‐scheme g‐C3N4/Bi2WO6 heterojunctions facilitate the effective separation and accumulation of photogenerated electrons at conduction band of g‐C3N4 and holes at valence band of Bi2WO6, resulting in hydroxyl and superoxide radicals for the redox of CIP. S‐CN‐40presents the highest CIP removal percent due to the effective heterogeneous interface and C–CN‐20 possesses the good application prospects in practice for the simple preparation process.

“…7(a)). 56,57 Furthermore, in the blank test, no change in the absorption intensity was observed for a long period with NaBH 4 , which indicates that the reduction reaction did not occur without the addition of the catalyst. Aer the addition of the Au/ATGO composites, the absorption peak at 400 nm owing to 4-nitrophenolate ions gradually decreased; at the same time, a new peak was observed at 296 nm indicating the formation of 4-AP.…”
