A stable 0D/1D photocatalyst constructed by ZnSnO3 quantum dots (QDs) and perylene diimide (PDI) supramolecular nanorods was successfully achieved via a simple in situ deposited method through an electrostatic attraction build-up strategy and exhibited marvel phenol degradation efficiency under visible-light irradiation. By engineering controllable 0D/1D hetero-interfaces, on the one hand, most of the light absorption sites from the PDI component remained exposed and, on the other hand, efficient interfacial charge transfer driven by a giant built-in electric field between the two components successfully led to great enhancement in charge separation. Importantly, besides the evidenced excellent structure and morphology stability, suppressed production of PDI·– after forming the heterostructure was also proved to be responsible for its robust cyclic photocatalytic activity. This stable and efficient visible-light-driven photocatalyst showed great development potential for removal of phenol pollutants with low concentrations.

In the present study, orange peel biochar has been utilized as the adsorbent for the removal of phenol from contaminated water. The biochar was prepared by thermal activation process at three different temperature 300, 500 and 700°C and are defined as B300, B500, and B700 respectively. The synthesized biochar has been characterized using scanning electron microscopy (SEM), X‐ray diffraction (XRD), Fourier transformation infrared spectroscopy (FTIR), RAMAN spectroscopy, X‐ray photoelectron spectroscopy (XPS), and UV–Vis spectroscopy. SEM analysis revealed a highly irregular and porous structure for B700 as compared with others. The parameters such as initial phenol concentration, pH, adsorption dosage, and contact time were optimized, and the maximum adsorption efficiency and capacity of about 99.2% and 31.0 mg/g was achieved for B700 for phenol adsorption. The Branauer‐Emmett‐Teller (BET) surface area and Berrate–Joyner–Halenda (BJH) pore diameter obtained for B700 were about 67.5 m2/g and 3.8 nm. The adsorption of phenol onto the biochar followed Langmuir isotherm showing linear fit with R2 = 0.99, indicating monolayer adsorption. The kinetic data for adsorption is best fitted for pseudo‐second order. The thermodynamic parameters ΔG°, ΔH°, and ΔS° values obtained are negative, which means that the adsorption process is spontaneous and exothermic. The adsorption efficiency of phenol marginally declined from 99.2% to 50.12% after five consecutive reuse cycles. The study shows that the high‐temperature activation increased the porosity and number of active sites over the orange peel biochar for efficient adsorption of phenol. Practitioner Points Orange peel is thermally activated at 300, 500, and 700°C for structure modification. Orange peel biochars were characterized for its structure, morphology, functional groups, and adsorption behavior. High‐temperature activation improved the adsorption efficiency up to 99.21% due to high porosity.

“…Polycyclic aromatic hydrocarbons (PAHs) are well-known persistent organic pollutants owing to their high mutagenicity, teratogenicity, and carcinogenicity, , among which, aromatic amines and phenols are two typical types of pollutants. − Aromatic amines could be specifically and catalytically oxidized by oxidase mimics in proper buffer solution, which is used for designing sensor array to identifying multiple aromatic amines . And also, phenols could be catalytically oxidized by laccase mimics (a kind of oxidase mimics), which are usually utilized to degrade phenols and to design sensors for detecting a single phenol (catechol, hydroquinone, 2-chlorophenol, 4-chlorophenol, and phenol) and even as a sensor array for multiple phenols − because multiple phenols are possibly coexisting in most cases. − As important synthetic industrial chemicals and intermediary products, aromatic amines and phenols are usually coexisting in water, , while the strategy that can simultaneously identify aromatic amines and phenols is rarely reported.…”

Oxidase-mimicking nanozymes are some of the most important nanozymes, which are investigated in various buffer concentrations. However, buffer concentration-dependent catalytic performance is rarely investigated. Herein, with o-phenylenediamine (OPD) as a substrate, the catalytic performance of Cu-Adenine oxidase mimic (fabricated with Cu 2+ as an active center and adenine as a ligand) gradually decreases upon Tris−HCl buffer concentration (C Tris−HCl ) increasing from 10 to 200 mM, exhibiting buffer concentration-dependent catalytic activity. Such buffer concentration-dependent catalytic activity is believed to be because Tris−HCl and OPD competitively bind with Cu-Adenine, leading to differences in catalytic activity. Similarly, with 2,4-dichlorophenol (2,4-DP) as a substrate and 4-aminoantipyrine (4-AP) as a chromogenic agent, the same results are obtained. However, with 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 3,3′,5,5′tetramethylbenzidine (TMB) as substrates, the catalytic oxidation cannot be observed at C Tris−HCl ≥ 50 mM. Tris−HCl and substrate competitively binding with Cu-Adenine produces buffer concentration-dependent catalytic performance. Subsequently, substrates are successfully expanded to other aromatic amines (p-phenylenediamine (PPD), 1,5-naphthalenediamine (1,5-NDA), 1,8-naphthalenediamine (1,8-NDA)) and phenols (phenol, 3-cresol, 1-naphthol). Based on the results, with 50 and 150 mM Tris− HCl buffer solutions as sensing channels, a Cu-Adenine-based colorimetric sensor array is constructed for discriminating four representative aromatic amines (OPD, PPD, 1,5-NDA, 1,8-NDA) and four phenols (2, phenol, as low as 50 μM. The performance is further validated through accurately identifying binary, quaternary, and even senary and octonary mixtures. Finally, the designed sensor array is successfully applied for identifying eight representative aromatic amines and phenols in river water, seawater, and sewage water, presenting great potential and valuable applications for large-scale scanning levels of aromatic amines and phenols in water samples.
