This study reports on the development of highly-efficient Pt/CuO-Fe 2 O 3 /TiO 2 monolithic catalysts for the low-temperature conversion of NO to N 2 via CO-SCR. In this case, ultrathin TiO 2 nanosheet arrays are designed to in situ grow on flexible Ti mesh to provide more spaces/areas for the loading of highly-dispersed Fe 2 O 3 and CuO active components. Furthermore, Pt nanoparticles with an average size of 1.30 nm are effectively decorated on the surface of CuO-Fe 2 O 3 /TiO 2 . The H 2 -TPR and NO-TPD results demonstrate that the excellent synergistic effect between TiO 2 , CuO, Fe 2 O 3 and trace amounts of Pt is conducive to enhance the adsorption of NO and finally promote the CO-SCR. The obtained Pt/CuO-Fe 2 O 3 /TiO 2 catalysts exhibit excellent CO-SCR performance with 100 % NO conversion, and 100 % N 2 selectivity at 250 °C, showing great potential of de-NO x application by using toxic CO as reductant in industry.

The fabrication of surfaces with varying wettability is crucial for developing Janus materials. In this study, a Janus Cu/Ti mesh with asymmetric wetting surfaces is fabricated using diffusion bonding. The Ti and Cu meshes are bonded through vacuum hot-pressing, forming a two-layer compositing, and the CuTi intermetallic compound is found at the interface. High-density TiO 2 nanostructures are synthesized on the Ti wire via hydrothermal treatment in NaOH. Subsequent immersion in a stearic acid solution, renders the Cu mesh hydrophobic, while the Ti mesh retains its hydrophilic properties, resulting in a Janus Cu/Ti mesh with asymmetric hydrophobic/superhydrophobic behavior. The unidirectional transport properties of this Janus mesh, including water penetration and bubble/oil manipulation, are systematically studied. Additionally, a superhydrophobic/hydrophilic Janus mesh is achieved by synthesizing CuO nanosheets on Cu mesh and applying surface modifications. This approach broadens the technological framework for fabricating Janus materials and enhances the potential applications of diffusion bonding, highlighting its versatile prospects.

Much attention has been focused on the fabrication of TiO 2 microspheres due to their excellent properties and attractive potential in many fields. Here, undoped 3D hierarchical TiO 2 microspheres (TMS) were synthesized in situ on Ti mesh using a hydrothermal method by varying NaOH concentration, reaction time and temperature. The 3D TMS grown along the surface of the woven wires of the Ti meshes, using the metal Ti meshes as a substrate, which resulted in improved conductivity. Meanwhile, the original Ti mesh with the macroporosity (due to the 15 % open area of the mesh) can act as fast proton mass diffusion. As a result, the flexible TMS-Ti photoelectrodes exhibit an excellent current density of 1.63 mA/cm 2 at a potential of 1.23 V (vs Ag/AgCl). Therefore, the in situ synthesis of TiO 2 microspheres on Ti mesh is highly desirable for flexible devices.

The construction of cost-effective, efficient, and sustainable energy storage systems is extremely important for future fuels globally. Nickel borates display important characteristics in electrochemical catalytic applications, whereas few reports have focused on their energy storage properties in supercapacitors . Herein, Ni 3 (BO 3 ) 2 nanospheres (NSs) are fabricated on titanium (Ti) mesh to afford Ni 3 (BO 3 ) 2 NSs@Ti using a simple and scalable electrodeposition technique, whose electrochemical performance is carefully studied. The Ni 3 (BO 3 ) 2 NSs@Ti obtained at 1.2 V (Ni 3 (BO 3 ) 2 NSs-1.2V) exhibits a higher specific capacitance of 663 F g −1 with a current density of 0.5 A g −1 . Furthermore, by directly employing Ni 3 (BO 3 ) 2 NSs-1.2V as the positive electrode and activated carbon as the negative electrode , an asymmetric supercapacitor (ASC) device can be fabricated and displays the energy density up to 30.6 Wh kg −1 at the power density of 400 W kg −1 . Hence, the facile electrodeposited Ni 3 (BO 3 ) 2 NSs can be a potential platform for energy storage applications .

In the present work, Ti mesh loaded with Ag “nanobosk” was prepared through electro-deposition and characterized with X-ray diffraction, scanning electron microscopy and X-ray photoelectron spectroscopy. Then, the surface enhanced Raman scattering of norfloxacin on the Ti mesh loaded with Ag “nanobosk” was directly explored in norfloxacin aqueous solution. In addition, for practical purposes, the surface enhanced Raman scattering of norfloxacin was studied as a function of content of Ag, pH of solution, ions in water, and salinity, respectively. At last, the surface enhanced mechanisms were discussed preliminarily. The results indicate that the Ti mesh loaded with Ag “nanobosk” is an ultrasensitive surface enhanced Raman scattering substrate for trace norfloxacin in water. When the concentration of norfloxacin is 1 × 10 −5 mol L −1 , the enhancement factor is approximately 5.1 × 10 3 at 1389 cm −1 . And the detection limit is up to 1 × 10 -10 mol L −1 for norfloxacin under optimal conditions. Our work provides a new strategy for designing a sensing platform which is sensitive to trace norfloxacin in water and can be applied in the routine detection.

Interfacial solar driven water evaporation (ISDWE) technology has been widely studied to desalinate seawater in aiming to alleviate the scarcity of clean water. In this paper, the ISDWE performance of Ti mesh was enhanced by anodized TiO 2 nanotube film and applied voltage, and the water evaporation rate increased from 1.20 kg•m −2 •h −1 to 2.48 kg•m −2 •h −1 . Due to hydrophilic and nanoporous nature of TiO 2 nanotube film, the solar absorptivity, wettability of Ti mesh was improved, the water evaporation enthalpy was reduced, and the water evaporation rate reached 1.98 kg•m −2 •h −1 . For the superior ISDWE performance with applied voltage, electrothermal effect and internal electrical filed were proved to be contributing factors. The solar irradiation can enhance the electrothermal effect for the semiconducting nature of TiO 2 . The internal electrical field can optimize the solar absorptivity and water evaporation enthalpy through doping TiO 2 and breaking water clusters. Moreover, the applied voltage also increased the salt-resistance property of Ti mesh coated with TiO 2 nanotube film. When increasing NaCl concentration, stable water evaporation rate was attainable under 1.2 V, whereas continuous deceleration of water evaporation occurred without external voltage. Therefore, our study provides strategies for achieving high efficient and salt-free seawater desalination by ISDWE technology.

In this work, a template-free hydrothermal strategy has been developed to fabricate 3D hierarchical MoS 2 microflowers on macroporous Ti mesh (MoS 2 MF-Ti) as a binder-free electrode for hydrogen evolution reaction (HER). It is found that the Ti mesh is able to provide an ideal platform for self-assembly of the MoS 2 nanosheets into the hierarchical microflowers. The as-prepared MoS 2 MF-Ti electrode is characteristic of meso/macro porous structures, abundant active edges and good conductivity. As a result, the MoS 2 MF-Ti demonstrates greatly enhanced electrocatalytic activity and stability toward HER due to its desirable structural features.

Graphical Hydrogen generation : The catalytic dehydrogenation of NaBH 4 in alkaline media for on-demand hydrogen generation can be effectively driven by self-supported Co(CO 3 ) 0.5 (OH)⋅0.11 H 2 O nanowire array on Ti mesh (CHNA/Ti), with a high hydrogen generation rate of 4000 mL min −1 g Co −1 and a low activation energy of 39.78 kJ mol −1 . In this work, for the first time, a cobalt carbonate hydroxide (Co(CO 3 ) 0.5 (OH)⋅0.11 H 2 O) nanowire array on Ti mesh (CHNA/Ti) was applied to drive the dehydrogenation of alkaline NaBH 4 solution for on-demand hydrogen production. Compared with other nanostructured Co-based catalyst systems, CHNA/Ti can be activated more quickly and separated easily from fuel solutions. This self-supported cobalt salt nanowire array catalyst works as an efficient and robust 3D catalyst for the hydrolysis reaction of NaBH 4 with a hydrogen generation rate of 4000 mL min −1 g Co −1 and a low apparent activation energy of 39.78 kJ mol −1 and offers an attractive system for on-demand hydrogen generation.

Highly efficient metal–organic framework (MOF)-based oxygen evolution reaction (OER) catalysts are desirable for water splitting, but their development remains challenging due to poor accessibility of coordinatively unsaturated metal (cum) sites and low intrinsic activity. A large-area three-dimensional (3-D) macroporous interconnected nanosheet array of Ni-1,3,5-benzenetricarboxylate has been in situ self-assembled on Ti mesh (TM) by using ethanol as the solvent and high-affinity oxide layer on TM to promote in situ nucleation. The obtained nanoarchitecture exhibits much superior catalytic activity compared to most reported catalysts including MOF-based catalysts, other precious-metal-free ones, and Ir/Ru-based ones. Additionally, this electrode undergoes no current decay after 300 cyclic voltammetry (CV) cycles and can maintain at 250 mA cm −2 for over 266 h. The excellent catalytic performance is mainly due to the 3-D macroporous and interconnected nanosheet array structure improving cum site exposure and charge transport and in situ activated cum cations enhancing OH − adsorption. This work not only develops a facile and economical approach to synthesize 3-D macroporous interconnected MOF nanosheet arrays to simultaneously increase the number, exposure, and intrinsic activity of active sites and facilitate charge transport for high-performance eletrocatalysis, but provides scientific insights into the mechanisms for self-assembly of this unique nanoarchitecture and for the high OER performance.

A scalable strategy with commercial feasibility was developed to in situ generate TiO 2 nanowires/amorphous CuS@TiO 2 nanolayer (TiO 2 /CuS@TiO 2 ) composites on the surface of titanium mesh through a sequent hydrothermal method, successive ionic layer adsorption and reaction (SILAR), and atomic layer deposition (ALD) techniques. The TiO 2 /CuS@TiO 2 composites could respectively harness the incident light with different spectra at the photothermal center (CuS, visible and near-infrared light) and photocatalytic center (TiO 2 , UV and visible light), which leads to the effective utilization of the solar energy. Benefiting from the CuS photothermal-induced local heating effect of CuS, the adjacent micro-zone temperature could be elevated and the activation energy barrier could be reduced by 10.5 kJ mol −1 , which promotes the activation of surface lattice oxygen and dissolved oxygen in the photocatalytic process. Meanwhile, the ALD generated TiO 2 nanolayer could both serve as reactive centers but also protecting armor for the CuS, which prohibited the peeling and oxidation of the thermal centers, leading to a high stability of the photocatalyst, which exhibits no obvious fading after 20-cycle reuse. A flow reactor was conceived and made by 3D print and the Ti-mesh based photocatalyst was integrated, which demonstrates high photocatlytic performances, manifesting its great potential for large-scale water treatment.
