“…The higher the catalyst dose is, the higher the photocatalytic efficiency. However, with increasing photocatalyst dosage, the increase in the methyl orange degradation rate decreased, [42] indicating that the degradation effect of methyl orange is not always be positively correlated with the dosage of the Ag 3 PO 4 /GO/NiFe 2 O 4 photocatalyst. There is an optimal photocatalyst dosage.…”

A new type of modified catalyst was prepared by a silver ammonia‐assisted precipitation method through a custom‐built electrochemical reactor, and the catalytic degradation of the azo dye methyl orange was studied under the synergistic effect of visible light. The optimum doping ratio for the loading of graphene oxide (GO) is 1.0 %. Under the optimum conditions, the degradation rate of Ag3PO4/GO/NiFe2O4 to methyl orange is 97.56 % when the light reaction time is 50 min. After three cycles, the degradation rate of methyl orange by Ag3PO4/GO/NiFe2O4 is 94.47 %. Through the free radical capture experiment, it is known that the contribution degree of the main active substances in the photocatalytic degradation of methyl orange is h + >⋅O2− >⋅OH. By forming a Z‐type heterojunction between Ag3PO4 and NiFe2O4, the recombination probability of photogenerated carriers is greatly reduced, and the stability of Ag3PO4 is improved.

“…In curve b, the intense peak at 669 cm −1 corresponds to the stretching vibration formed by O−Sn−O bond of Eu‐SnO 2 quantum dots. The abnormal peak at 535 cm −1 may be due to the defects on the nanocrystal surface, since lattice dislocation changes the local symmetry of the crystal, allowing the occurrence of forbidden vibration mode [43] . Amides I (1653 cm −1 ) and II (1540 cm −1 ) regions shown in curve c are typical peaks of the Lox polypeptide bonding.…”

“…The abnormal peak at 535 cm À 1 may be due to the defects on the nanocrystal surface, since lattice dislocation changes the local symmetry of the crystal, allowing the occurrence of forbidden vibration mode. [43] Amides I (1653 cm À 1 ) and II (1540 cm À 1 ) regions shown in curve c are typical peaks of the Lox polypeptide bonding. Particularly, the amide I absorption peak is ascribed to stretching vibrations of the peptide carbonyl groups, while the amide II absorbance region is attributed to NÀ H bending and CÀ N stretching of the polypeptide bonds.…”

In this work, Eu3+‐doped SnO2 nanoparticles are prepared and embedded into MXene (Ti3C2) laminates, and Ti3C2@Eu‐SnO2 composites are obtained. Cyclic voltammetry (CV) and scanning electron microscopy (SEM) characterization show that the composites have excellent electrochemical properties and unique morphology. The electrochemical impedance spectroscopy (EIS) and Fourier transform infrared spectrometer (FTIR) results of lactate oxidase (Lox) immobilized on Ti3C2@Eu‐SnO2 indicate that Eu‐SnO2, Ti3C2, and Lox have a good hybrid coordination and biocompatibility. The enzymatic electrochemical biosensor constructed with Ti3C2@Eu‐SnO2/Lox on glassy carbon electrode (GCE) reveals an excellent linear relationship in the lactate concentration ranging from 1.0×10−9 to 1.0×10−4 mol L−1. It has a low detection limit of 3.38×10−10 mol L−1 and high sensitivity of 4.815 mA nmol−1 L cm−2. Furthermore, the fabricated biosensor has a reasonable recovery rate for determining lactate in human serum.

“…The literature [61][62][63][64][65] contains photodegradation studies using various SnO 2 modified photocatalysts for the removal of organic pollutants in aqueous solutions. When compared with previous studies (Table 2), it can be concluded that the time required for the maximum removal of dye (20 μM) was less, at 180 min.…”

In this study, n‐type SnO2 was synthesized and modified with p‐type NiWO4 to create a new NiWO4/SnO2 p–n heterojunction photocatalyst for effective organic dye degradation (Amaranth). X‐ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV–Vis diffuse reflection spectroscopy (DRS), and Brunauer–Emmett–Teller (BET) surface area analysis were all used to evaluate the synthesized materials. Through its internal electric field and strong driving force, the composite photocatalyst with p–n heterojunction considerably enhances charge generation and suppresses photogenerated electron–hole recombination, which would be beneficial to boost their photocatalytic performance. At 180 min, the NiWO4/SnO2 photocatalyst had the maximum efficiency for degrading Amaranth, up to 93%. Finally, the experimental results were used to rationally analyze the photodegradation mechanism.
