The frequent occurrence of pesticides and nanoparticles in aquatic environments raises ecological concerns. Tebuconazole (TEB) is a widely used triazole fungicide, and zinc oxide nanoparticles (ZnO NPs) are one of the commonly used engineered nanoparticles. Both are frequently detected in the aquatic environment, yet their combined effects on aquatic organisms remain inadequately understood. In this study, we investigated the impacts of coexposure to environmentally relevant concentrations of ZnO NPs on the toxicity and bioaccumulation of TEB in zebrafish (Danio rerio). The 96-h median lethal concentration (LC50) of TEB to zebrafish was 6.45 mg/L. Coexposure to ZnO NPs (1–100 mg/L) led to a slight increase in acute toxicity of TEB. Long-term (28-day) coexposure to environmentally relevant concentrations of TEB and ZnO NPs exacerbated oxidative stress and apoptosis, decreased the activity of the detoxification enzyme carboxylesterase, and upregulated cytochrome P450 activity. Additionally, ZnO NPs did not enhance the accumulation of TEB but prolonged its clearance and altered its bioaccumulation pattern. These results indicate that the presence of ZnO NPs may increase the potential risk associated with TEB exposure in zebrafish, underscoring the need for further investigation of the interactive effects of pesticides and engineered nanomaterials in aquatic ecosystems.

Flexible wearable pressure sensors exhibit great potential in human activity tracking. Designing visual sensors that integrate active luminescence and motion monitoring is a current research focus. This study proposed a novel five-layer mechanoluminescent piezoelectric sensor (MPS) that synergistically combined the piezoelectricity of Nd-ZnO NRs loaded carbonized silk fabric (CSF) with the luminescent capability of ZnS:Cu/PDMS. A low-temperature hydrothermal method was utilized to incorporate Nd 3 + into the ZnO lattice, while loading the ZnO NRs onto CSF. Nd 3+ was used as a p-type dopant to regulate the piezoelectricity of ZnO, yielding a highly sensitive piezoelectric layer. The resulting MPS exhibited high pressure sensitivity ( S = 27.48 mV/kPa, 0–100 kPa), excellent pressure response (Response time = 150 ms), and outstanding stability (>2400 cycles). Experiments demonstrated that MPS can effectively monitor human joint movement. Due to the introduction of ZnS:Cu, MPS emitted pulsed light which intensity was linearly correlated with the applied stress (R 2 = 0.98). During the nighttime running test, MPS emitted electrical and optical signals corresponding to the bending angles and frequencies of human joints. MPS features visual and electrical dual-mode sensing capabilities, enabling simultaneous monitoring of pressure and strain stimuli to achieve stress visualization. This study provides a feasible approach to developing intelligent sensing systems with active luminescence.

In the present work, ZnO quantum dots (QDs) have been prepared by the sol–gel method, and the performance of the QDs has been improved. The effect of Cd concentration on the structural and luminescent properties of the QDs, as well as the effect of the mass ratio of trioctylphosphine oxide (TOPO)/octadecylamine (ODA), has been investigated. The ZnO and Cd-doped ZnO QDs have hexagonal wurtzite structures and are 3 to 6 nm in diameter. When the Cd content was increased, the QD particle size was reduced; this effect was confirmed in the corresponding ultraviolet–visible spectra. The fluorescence intensity was simultaneously enhanced significantly. Both the UV and fluorescence spectra were blue-shifted. The luminous intensity was further enhanced when the QDs were modified with TOPO/ODA. Fourier transform infrared and X-ray diffraction techniques proved that the polymer successfully coated the surfaces of the QDs. A TOPO/ODA mass ratio of 1:2 was determined to result in the best optical performance among the different ratios examined. The results showed that the described synthetic method is appropriate for the preparation of doped QDs with high-fluorescence quantum efficiency.

A highly sensitive surface-enhanced Raman spectroscopy (SERS) method for the detection of acephate was established by using the substrate of silver nanoparticles (AgNPs) modified with N-acetyl-L-cysteine (NAC) and zinc oxide (ZnO). The Raman signal enhancement factor (EF) of acephate by the substrate of ZnO/NAC/AgNPs can be reached 4.95 × 10 6 . The ultraviolet-visible spectroscopy (UV-vis), high-angle annular dark field scanning transmission electron microscopy (HAADF-STEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), zeta potential, Fourier transform infrared spectra (FT-IR) and thermogravimetric analysis (TGA) were used to characterize the substrate of ZnO/NAC/AgNPs. The mechanism of electromagnetic enhancement (EM) assisted by chemical enhancement (CM) was elucidated in detail. The optimal experimental conditions were selected. The interference experiments showed that this method had high selectivity in complex substrates. There was a good linear relationship between acephate concentration and SERS signal intensity in the range of 6.00 × 10 −9 mol L −1 – 8.00 × 10 −7 mol L –1 , and the linear equation was I SERS = 85.02 c + 24712.49 ( r = 0.9982, c : nmol L −1 ) with the limit of detection (LOD) was 3.40 nmol L –1 (3 σ / S ). The SERS method was successfully applied for the detection of acephate residues in vegetable samples, and the recovery was in the range of 95.3% – 104% ( n = 5).

To further advance the application of flexible piezoelectric materials in wearable/implantable devices and robot electronic skin, it is necessary to endow them with a new function of antibacterial properties and with higher piezoelectric performance. Introducing a specially designated nanomaterial based on the nanocomposite effect is a feasible strategy to improve material properties and achieve multifunctionalization of composites. In this paper, carbon dots (CDs) were sensitized onto the surface of ZnO to form ZnO@CDs nanoparticles, which were then incorporated into polyvinylidene fluoride-hexafluoropropylene (PVDF-HFP) to obtain a multifunctional composite. On the one hand, the antibacterial property of ZnO was improved because CDs had good optical absorption of visible light and their surface functional groups were favorable for electrostatic adsorption with bacteria. Therefore, ZnO@CDs endowed the composite with an outstanding antibacterial rate of 69.1% for Staphylococcus aureus. On the other hand, CDs played a bridging role between ZnO and PVDF-HFP, reducing the negative effect of ZnO aggregation and interface incompatibility with PVDF-HFP. As a result, ZnO@CDs induced β-phase formation of 80.4% in PVDF-HFP with a d33 value of 33.8 pC N–1. The multifunctional device exhibited excellent piezoelectric and antibacterial performance in the application of energy harvesters and self-powered pressure sensors.

The exploration of advanced electrochemical sensors towards highly toxic arsenic(III) has attracted growing interest in recent times. Herein, a ZnO decorated nanoporous Au (NPG) microelectrode was fabricated via a facile electrochemical alloying/dealloying method followed by thermal treatment, and developed for the electrochemical sensing of toxic As(III). Inspired by the electrochemical deposition of Zn and the formation of Au-Zn nanostructure on the surface of the Au microelectrode during the alloying/dealloying process, the in-situ evolution of the formed Au-Zn nanostructure to ZnO nanoparticles wrapped on the nanoporous Au surface was achieved. The ZnO/NPG microelectrode exhibited excellent electrochemical performance towards As(III) detection in near-neutral conditions (0.1 M phosphate buffer solution (PBS), pH: 5.0). A high sensitivity of 1.366 μA·ppb −1 ·cm −2 with a low limit of detection of 0.30 ppb (S/N = 3) was achieved at concentrations ranging from 1.0 ppb to 260 ppb. Moreover, the prepared ZnO/NPG microelectrode was successfully applied in the analysis of As(III) in tap and lake water samples with satisfactory recovery rates. The ZnO/NPG microelectrode presented exciting prospects for the electrochemical analysis of As(III) in near-neutral conditions.

In this paper, a MOD (Metal organic decomposition) Al doped ZnO (AZO) ink was directly used for inkjet printing transparent and conductive AZO films. The ink was synthesized by using zinc acetate dihydrate and aluminum nitrate nonahydrate as precursor, 1,2-diaminopropane as a complexing agent, ethyl alcohol as solution, ethyl cellulose as addition agent. The thermal decomposition behavior of the MOD ink was investigated. The various MOD AZO inks were inkjet printed and heated at different temperatures for different times. The films were studied by X-ray diffraction, scanning electron microscopy, resistivity measurements and ultraviolet–visible spectroscopy. The results demonstrated that 0.2 M AZO (2 at%) film heated at 250 °C for 120 min showed highly preferential growth along the c -axis, uniform microstructure with a resistivity of 0.03 Ω cm and high transmittance more than 90% in the visible range of the spectrum with an optical band gap at 3.326 eV.

Semiconductor-based photocatalysis is of great practical significance to degrade persistent organic pollutants (POPs). However, it still faces challenges and always in pursuit to construct a photocatalyst system with efficient charge separation and strong redox capacity. Herein, a Z-scheme energy band configuration in a hierarchical heterostructure composed of two-dimensional (2D) ZnIn2S4 nanosheets and zero-dimensional (0D) ZnO nanoparticles was fabricated for the degradation of tetracycline (TC)—one of the typical POPs. On the one hand, the Z-scheme heterojunction inhibits the recombination of charge carriers and preserves the strong redox capacity of ZnIn2S4 and ZnO. On the other hand, the hierarchical microstructure and the 2D/0D subunits endow the ZnIn2S4/ZnO photocatalyst with good light harvesting, intimate interface contact, and short charge transfer. As a result, the hybrid photocatalyst exhibited a high reaction rate constant of 0.074 min−1 for TC degradation, which is 5.4 and 2.8 times that of the pure ZnIn2S4 and ZnO, respectively. This work provides new insight into the integration of energy band engineering and morphology modulation to design advanced photocatalytic systems for POP treatment.

Precise control over the structure and morphology of nano/microarchitectures is the topic of immense interest to tune their physical features and chemical aspects for desired applications. In this work, a novel and effective Ni(OH) 2 three-dimensional nanosheet-coated marigold-like ZnO microflower (mg-ZnO@Ni(OH) 2 NSs) hybrid is designed for the nonenzymatic electrochemical determination of glucose. The morphological evolution of mg-ZnO and mg-ZnO@Ni(OH) 2 NSs was achieved by a one-pot solvothermal strategy through control over the reaction conditions without any assistance of an external shape-controlling surfactant. Furthermore, the as-fabricated mg-ZnO and mg-ZnO@Ni(OH) 2 NSs were systematically evaluated by different spectroscopic, microscopic and electrochemical characterization tools. The results indicate that highly exposed homogeneous nanocorners of mg-ZnO and the synergetic effect of Ni(OH) 2 coating, collectively improve the electrocatalytic efficiency of the designed catalyst. The mg-ZnO@Ni(OH) 2 NS-based sensing electrode exhibits excellent amperometric performance for glucose monitoring, comprising satisfactory sensitivity (259.78 and 62.82 μA mM −1 cm −2 ), wide linear range (0.084–0.941 mM and 0.941–6.50 mM), low limit of detection (0.06 µM, S / N = 3), good stability and high detection selectivity. Moreover, the designed sensor is promising for the potential application in the real-time glucose detection of human serum samples.

The utilization of metal oxide-zeolite catalysts in the syngas-to-olefin reaction is a promising strategy for producing C 2 –C 4 olefins from non-petroleum resources. However, the effect of the crystal phase of metal oxides on the catalytic activity of these oxides is still ambiguous. Herein, typical metal oxides (ZnO/ZrO 2 ) with different crystal phases (monoclinic ( m -ZrO 2 ) and tetragonal ( t -ZrO 2 )) were employed for syngas conversion. The (ZnO/ m -ZrO 2 +SAPO-34) composite catalyst exhibited 80.5% selectivity for C 2 –C 4 olefins at a CO conversion of 27.9%, where the results are superior to those (CO conversion of 16.4% and C 2 –C 4 olefin selectivity of 76.1%) obtained over (ZnO/ t -ZrO 2 +SAPO-34). The distinct differences are ascribed to the larger number of hydroxyl groups, Lewis acid sites, and oxygen defects in ZnO/ m -ZrO 2 compared to ZnO/ t -ZrO 2 . These features result in the formation of more formate and methoxy intermediate species on the ZnO/ m -ZrO 2 oxides during syngas conversion, followed by the formation of more light olefins over SAPO-34. The present findings provide useful information for the design of highly efficient ZrO 2 -based catalysts for syngas conversion.

Multi-component promoters may efficiently improve the catalytic performance of the primary Cu-based catalysts in the Rochow-Müller reaction, but this approach is not well explored, and the roles of the promoters are not very clear. Herein, we report the ZrO 2 -supported CuO catalyst (CuO/ZrO 2 ) modified with a co-promoter of ZnO, Sn, and CuP prepared by a simple dry ball-milling method. The co-promoter could significantly increase the amount of surface adsorbed oxygen and improve the reducing ability of catalysts, facilitating the formation of the active Cu 3 Si phase and further advancing dimethyldichlorosilane ((CH 3 ) 2 SiCl 2 , M2) selectivity and Si conversion in the Rochow-Müller reaction. Compared to the state-of-the-art commercial catalyst, these CuO/ZrO 2 catalysts with the co-promoters all showed enhanced catalytic activity. Especially, the CuO/ZrO 2 catalyst with the co-existence of ZnO, Sn, and CuP promoters achieved the highest M2 selectivity and Si conversion, attributed to its most abundant surface adsorption oxygen and the strongest reducibility. This work opens up a new avenue to improve the catalytic activity of Cu-based catalysts for the Rochow-Müller reaction.

The heterogeneous catalytic activation of peroxymonosulfate (PMS) for wastewater treatment is attracting increased research interest. Therefore, it is essential to find a sustainable, economical, and effective activated material for wastewater treatment. In this study, metal–organic framework (MOF)-5 was used as the precursor, and a stable and recyclable material ZnO@Ni 3 ZnC 0.7 that exhibited good adsorption and catalytic properties, was obtained by the addition of nickel and subsequent calcination. To investigate and optimize the practical application conditions, the elimination of rhodamine B (RhB) in water was selected as the model process. This study demonstrated that the degradation of organic matter in the system involved a coupling of the adsorption and degradation processes. Based on this, the mechanism of the entire process was proposed. The results of scanning electron microscopy, infrared spectrum analysis, and theoretical analysis confirmed that the van der Waals forces, electrostatic attraction, and hydrogen bonding influenced the adsorption process. Electron paramagnetic resonance analysis, masking experiments, and electrochemical tests conducted during the oxidative degradation process confirmed that the degradation mechanism of RhB included both radical and non-free radical pathways, and that the surface hydroxyl group was the key active site. The degradation of the adsorbed substrates enabled the regeneration of the active sites. The material regenerated using a simple method exhibited good efficiency for the removal of organic compounds in four-cycle tests. Moreover, this material can effectively remove a variety of organic pollutants, and can be easily recovered owing to its magnetic properties. The results demonstrated that the use of heterogeneous catalytic materials with good adsorption capacity could be an economical and beneficial strategy.
