Since most superamphiphobic coatings contain fluorinated materials, finding eco-friendly alternatives is essential. In recent years, researchers have focused on integrating eco-friendly photocatalytic materials into superhydrophobic coatings to degrade organic pollutants effectively. We successfully designed a porous ZrO 2 @TiO 2 (porous ZT) photocatalyst using a combination of the solvothermal, sol–gel, and calcination methods. Porous ZT was modified with polydimethylsiloxane (PDMS) to create a kind of ZrO 2 @TiO 2 @PDMS (porous ZTP) suspension. The ZTP suspension was then sprayed onto various substrates and heated at 400 °C for 2 min to produce a porous ZrO 2 @TiO 2 @PDMS (porous H-ZTP) composite coating. The porous H-ZTP coating demonstrates extremely low surface energy (2.37 mN/m), allowing it to prevent contamination from various liquids encountered in daily life while exhibiting outstanding superhydrophobic properties (WCA > 160°, SA < 2°). Additionally, it can decompose organic substance (RhB) under light irradiation, showcasing effective physical and chemical self-cleaning abilities. After exposure to ultraviolet light, the coating can decompose oleic acid and restore its initial superhydrophobic state. Further investigation into the mechanism of photocatalytic degradation reveals that the unique heterojunction structure of the porous ZT significantly enhances its photocatalytic activity. The porous H-ZTP applied to stainless steel mesh shows excellent flux (40,000 L·h −1 m −2 ) and efficiency (99 %) for oil–water separation. This research is significant for developing and applying self-cleaning coatings that combine physical superhydrophobic and chemical photocatalytic properties.

Here, an ultrasensitive zirconium oxide/reduced graphene oxide (ZrO 2 /rGO) non-enzymatic electrochemical sensor was developed for discriminating multicomponent (MP: methyl parathion; FEN: fenitrothion; PAR: paraoxon) aromatic OPs. Specifically, ZrO 2 nanosheets of uniform size (∼50 nm) were fabricated using hierarchically structured GO paper as a sacrificial template, and the prepared ZrO 2 nanofilms exhibited layered structure and high specific surface area due to the nano-confinement of the GO sheets. According to the Lewis acid-base theory and the intrinsic electrochemical properties of OPs, the as-prepared ZrO 2 nanosheets exhibited efficient enrichment and sensing of OPs. Meanwhile, coupled with a linear discriminant analysis (LDA) method, it could accurately discriminate complex mixtures of pesticides. Subsequently, a portable ZrO 2 /rGO sensing platform with a high pore structure was constructed by vacuum filtration to further enhance the detection sensitivity for in-situ determination of OPs. Employing cabbage as a real sample to validate the sensing platform, the two typical factor score plots explained 100 % of the total variance, confirming the reliability of the paper-based sensors in distinguishing 13 different proportions of mixed samples. These efforts provide promising strategies for the development of efficient, portable and sensitive electrochemical sensors for OPs.

Crystal structure of catalyst support has great influence on its surface and electronic properties. Thus, tuning the crystal phase may adjust the catalytic activity. Herein, we prepared a series of monoclinic, tetragonal and mixed phase of Co/ZrO 2 catalysts, denoted as Co/m-ZrO 2 , Co/t-ZrO 2 and Co/Mix-ZrO 2 . They showed different hydrogenation and hydrogenolysis activities in conversion of 5-hydroxymethylfurfural (HMF) to 2,5-dimethylfuran (DMF). The characterization and catalytic performance indicated that the interaction between cobalt and t-ZrO 2 resulted in cobalt electron-deficiency and higher concentration of Zr(III) species, which contributed to the higher hydrogenation activity of carbonyl on Co/t-ZrO 2 than Co/m-ZrO 2 . While the hydrogenolysis of C OH group showed higher efficiency on Co/m-ZrO 2 , which was determined by the acid concentration on the surface of catalysts. The combination of both high hydrogenation and hydrogenolysis activities in Co/Mix-ZrO 2 achieved the highest yield of DMF (90.7 %) under mild conditions of 130 °C and 1 MPa H 2 .

The non-selective decomposition of hydrogen peroxide into hydroxyl radicals often plagues heterogeneous oxidation, critically limiting its chemoselectivity for applications like oxidative desulfurization (ODS). Here, we demonstrate a strategy to program the H 2 O 2 activation pathway by designing a ZrO 2 @W 2 C-WO x heterostructure. Interfacial electron transfer from ZrO 2 to W 2 C establishes a built-in electric field, inducing an amorphous, mixed-valent WO x shell. This unique electronic interface enables synergistic dual-site activation of H 2 O 2 at adjacent Zr and WO x motifs, promoting a surface peroxo-intermediate pathway that selectively yields singlet oxygen ( 1 O 2 ). The catalyst exhibits a high turnover frequency (TOF) of 470 h −1 for ODS under mild conditions. Crucially, it demonstrates exceptional chemoselectivity, with reactive oxygen species (ROS) partitioning dominated by 1 O 2 ( 1 O 2 ≫ •O 2 − > •OH). This selectivity ensures robust performance across high sulfur loadings (500–2000 ppm S) and in the presence of fuel-relevant interferents. The catalyst's proven stability and low leaching highlight its industrial potential. By engineering an interfacial charge-transfer heterojunction with a built-in electric field coupled with a redox-active WO x shell, this work provides a blueprint for steering ROS generation toward non-radical pathways for precise, selective oxidation.

Chlorogenic acid (CGA), a dietary polyphenol with antioxidant and therapeutic benefits, can be harmful at high concentrations, necessitating sensitive detection in food. This study presents a ZrO 2 -ZrC-doped laser-induced graphene (ZrO 2 -ZrC-LIG) electrode prepared via a one-step laser carbonization of UiO-66/polyimide film. Structural analysis reveals a three-dimensional porous network with uniformly dispersed ZrO 2 and ZrC nanoparticles in graphene, which increases defect density, conductivity and surface area. The optimal conditions of laser-induced parameters such as power and carving depth for the electrode fabrication were selected. Under the optimal conditions, the electro-oxidation of CGA on the ZrO 2 -ZrC-LIG electrode was carefully investigated with electrochemical parameters calculated. The presence of ZrO 2 , ZrC and LIG exhibited an enhancement to the CGA oxidation with a pair of well-define redox peaks appeared, which was attributed to the faster electron transfer, higher electrocatalytic activity and synergistic effects. When integrated with a wireless portable electrochemical workstation, the fabricated sensor shows excellent analytical performance for CGA detection, including a wide linear range (0.1 μM to 1.0 mM), a low detection limit of 33 nM (3σ), along with high selectivity, stability, and reproducibility. When applied to apple and Eucommia ulmoides samples, it achieves the recoveries of 99.26–103.14%, confirming good analytical reliability. This simple and scalable method offers a promising strategy for developing flexible, portable electrochemical sensors for food safety and nutrition monitoring.

Fe 2 O 3 /ZrO 2 nanocomposite photocatalyst was successfully prepared by coprecipitation method for the degradation of diesel pollutants in seawater under visible light. The effects of doping ratio, calcination temperature, photocatalyst dosage, initial diesel concentration, H 2 O 2 concentration, and reaction time on the photocatalytic removal efficiency were investigated. Moreover, the optimal conditions for Fe 2 O 3 /ZrO 2 nanocomposite photocatalyst to degrade marine diesel pollution were determined. The removal efficiency of diesel by nanocomposite photocatalyst could reach 97.03%. A photocatalyst-loaded polypropylene polyhedral ball was prepared, and the removal efficiency of diesel by photocatalyst-loaded polypropylene polyhedral ball decreased from 99.35 to 68.84% after four recycling cycles.

Recent advances in the fabrication of organic–inorganic hybrid membranes have received a lot of attention in membrane technology for oily wastewater treatment. In this work, a hydrophilic PVDF hybrid membrane based on poly(N-acryloylmorpholine)-grafted ZrO2 nanoparticles (ZrO2-g-PACMO), was prepared via a simple phase inversion method. PACMO was firstly grafted onto the ZrO2 nanoparticles via radical polymerization, avoiding the aggregation of ZrO2-g-PACMO nanoparticles that was characterized by a sedimentation test. Then, the effects of the ZrO2-g-PACMO nanoparticles on the structures and performances of resultant hybrid membranes were systematically investigated. The cross-section and surface morphology of the hybrid membranes were observed by field emission scanning electron microscopy and atomic force microscopy. The results indicated that the higher concentration of ZrO2-g-PACMO nanoparticles in the casting solution led to a thicker sponge-like sub-layer and a rougher surface of hybrid membranes. The prepared PVDF/ZrO2-g-PACMO hybrid membrane exhibited a lower amount of adsorbed protein than that of the pristine PVDF membrane. This behavior was revealed by pure water contact angle measurement and force–extension curves. It was also found from the oil/water filtration that the total fouling (Rt) and irreversible fouling (Rir) were remarkably reduced, because of the higher hydrophilicity of hybrid membranes. Furthermore, the as-prepared membranes possessed also improved separation efficiency against oil/water mixtures and the rejection ratio was as high as 99.9%. Generally, a PVDF/ZrO2-g-PACMO membrane may provide potential application for efficient oil/water separation.

Based on the previous work on Si 3 N 4 -ZrB 2 , the addition of 2.5 vol.% ZrB 2 promoted α - to β -Si 3 N 4 phase transformation, bimodal microstructure, and toughness and strength improvement after hot-pressing at 1500 °C. However, the mechanism needed to be further explored. In the present work, the effect of ZrB 2 and its oxide impurities (ZrO 2 and B 2 O 3 ) on phase composition, microstructure and mechanical properties of Si 3 N 4 ceramics with MgO-Yb 2 O 3 additives were studied. Results showed that the addition of B 2 O 3 had no influence on Si 3 N 4 ceramics, whereas the addition of ZrO 2 inhibited the α - to β -Si 3 N 4 phase transformation, formed an uniform equiaxed microstructure, and deceased the toughness and strength. The positive effect of oxide impurities can be eliminated. Based on the STEM analysis , the possible reason was that the addition of ZrB 2 led to the formation of Si-Mg-O-N-Yb-Zr-B liquid phase , and then promoted α - to β -Si 3 N 4 phase transformation.

The selective oxidation of furfural (FF) to 2-furoic acid (FA) represents a significant route toward sustainable chemical production. However, existing catalytic systems often suffer from limitations such as low substrate concentrations, harsh reaction conditions, and inadequate selectivity. In this study, a series of Ag/ZrO 2 catalysts with varying Ag loadings were prepared via a deposition–precipitation method and were used for the aerobic oxidation of FF to FA under mild conditions. The effects of metal loading, catalyst mass, reaction temperature, reaction time, and oxygen pressure on FF conversion and FA selectivity were systematically investigated. Under optimized conditions, nearly 100% FA was achieved under 10 wt% FF concentration at low-temperature (ca. 5 °C), while a high selectivity of 90.3% toward FA was maintained even at 20 wt% FF. The catalysts also exhibited excellent recyclability, retaining over 85% FA selectivity after five consecutive cycles. Comprehensive characterization techniques, including XRD, XPS, and HRTEM, were employed to elucidate the structure-activity relationship of the catalysts. The experimental and characterization findings propose a possible reaction mechanism involving synergistic effects of Ag 0 sites for dehydrogenation and ZrO 2 oxygen vacancies for O 2 activation. This work represents a notable advance in the field, as it develops the high efficient catalytic system under high FF concentrations and low-temperature conditions for the first time.

Producing the strong metal-support interaction (SMSI) interface and highly reactive oxygen species is a great challenge for catalytic oxidation of formaldehyde (HCHO) at room temperature over supported metal catalysts. Herein, we report a conceptual oxygen vacancy ( V O ) associated SMSI interface of Pt-ZrO 2 nanoparticles for HCHO catalysis at room temperature, exhibiting interfacial dependent reactive oxygen species (O*) formation. The V O on the ZrO 2 support captures and activates the molecular O 2 , then proceeds to generating the reactive oxygen atom (O*) with a lower activation barrier of 0.3 eV. The generated O* tends to link the (1 1 0) surface of ZrO 2 and the (1 1 1) surface of Pt as an electronic transmission channel for the selective catalytic oxidation of HCHO adsorbed on the (1 1 0) surface of ZrO 2 , accelerating the direct generation of formate species and mineralization of HCHO. The Pt- V O -ZrO 2 achieves high HCHO removal and HCHO conversion (>95%) at 20 °C. These findings will consolidate the fundamental theories of room temperature catalytic reactions via constructing the SMSI interface engineering for wide environmental applications.

The development of efficient photocatalysts for selective organic transformations under visible light remains a major challenge in sustainable chemistry. In this study, we present a straightforward solvothermal strategy for fabricating a defect-engineered ZrO 2 /UiO-66-NH 2 hybrid material with abundant oxygen vacancies, enabling the visible-light-driven oxidation of benzyl alcohol to benzaldehyde. By optimizing the solvothermal treatment duration, the composite (UiO-66-NH 2 -2 h) achieves a 74.1% conversion of benzyl alcohol with > 99% selectivity toward benzaldehyde under mild conditions, substantially outperforming pristine UiO-66-NH 2 . Structural and mechanistic studies reveal that the solvothermal process induces the in situ formation of ultrasmall, uniformly dispersed ZrO 2 nanoparticles (~ 2.3 nm) within the MOF matrix, while simultaneously generating abundant oxygen vacancies, as confirmed by XPS, EPR, and HRTEM analyses. The defect-mediated electronic structure of the ZrO 2 /UiO-66-NH 2 hybrid enhances visible-light absorption, facilitates charge carrier separation, and promotes efficient activation of O 2 into superoxide radicals (·O 2 − ), the primary reactive species. Transient photocurrent measurements and electrochemical impedance spectroscopy further verify the improved charge separation efficiency. The synergistic interplay between oxygen vacancies and the intimate ZrO 2 /UiO-66-NH 2 interface provides a unique defect-mediated charge transfer pathway, distinguishing this system from conventional heterojunctions. This study demonstrates a facile, one-step approach to integrate defect engineering with interfacial hybridization in MOF-based photocatalysts, offering a scalable route for solar-driven organic synthesis.

Metallic nanoparticles can generate photoexcited hot carriers on the femtosecond scale under light excitation, which holds immense significance for applications such as optical communication and ultrafast imaging. In this study, a tunnelling junction structure with ZrO2 as the dielectric layer is designed and fabricated to achieve efficient hot hole collection between Au nanoparticles and P-type Si. Through characterizations of photoconductive atomic force microscopy, the electrical transition from an ohmic contact to a tunneling junction is confirmed, and the transfer pathway of Au hot holes to P-type Si upon 520 nm excitation is clearly observed. The impact of the tunneling structure on device performance is investigated through the fabrication of Si/ZrO2/Au/TiO2 photodiodes. The performance tests show that hot hole collection by the tunneling effect significantly enhances a range of parameters, e.g., external quantum efficiency by 250%. Noticeably, the external quantum efficiency attributed to photogenerated hot carriers under 520 nm excitation is estimated to exceed 2.5%. Moreover, the transient photoresponse of the photodiodes is examined with a typical rising time of less than 20 ns.
