Polypyrrole deposited on titanium mesh (PPy–TiM) was fabricated via a galvanostatic method with titanium mesh as the substrate to electrochemically deposit polypyrrole (PPy) doped with p -toluene sulfonate anions. The influence of the deposition time on the characteristics of the PPy–TiM samples was investigated. Then, semitransparent flexible electrochemical capacitors were assembled with the optimal samples of PPy–TiM as electrodes and H 3 PO 4 –poly(vinyl alcohol) as the gel electrolyte. The testing results show that PPy in the optimal PPy–TiM electrode had a specific capacitance of about 326 F/g, and the capacitance of the assembled cells still remained unchanged or up even after 20,000 cycles. Just as expected, the cells possessed semitransparent and good flexibility, and three cells connected in series could drive an LED device. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2017

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.

Films of polypyrrole/graphene on titanium mesh were prepared by electrochemical reduction of the fresh dried foam films of graphene oxide followed by an electrochemical polymerization of pyrrole. The as-obtained composite had highly surface area, conductivity, and could be used as the electrode for supercapacitors, especially directly used as the active materials in free of binders while the Ti mesh worked as the collector. Plenty of polypyrrole nanoparticles formed on the surface of reduced graphene film, and some fiber-like aggregates could be formed during the polymerization, which worked as the material for pseudo-capacitance. The specific capacitance of the supercapacitor reached 400 F/g and showed high stability with retaining capacitance of 82% after 5000 cycles, indicating that the nanocomposite is a suitable active material for supercapacitors.

In this work, we demonstrate the first use of NiCoP nanosheet array on Ti mesh (NiCoP NA/Ti) as an efficient catalyst for hydrolysis of NaBH 4 in alkaline media . This catalyst shows a low activation energy of 52.68 kJ/mol for NaBH 4 hydrolysis meanwhile the hydrogen generation rate can achieve 3016.79 mL/min/g (NiCoP) at 303 K, outperforming most reported Co-based noble-metal-free catalysts and some noble-metal catalysts. Remarkably, the catalyst exhibits high recyclability , durability and controllability for on-demand hydrogen generation in alkaline NaBH 4.

The development of advanced materials with superwettability has captured much research interest, because of the increasing environmental concerns and technological requirements. In this work, a titanium mesh coated with copper micro/nanostructures was fabricated via chemical immersion and annealing treatment. The resulting mesh surface consists of titanium and copper oxides with special dendritic and island-like micro-nano binary structures and exhibited remarkable superhydrophobic/superoleophilic property. The superhydrophobic/superoleophilic Ti mesh (SSTM) proved to be efficient for the separation of various water-oil mixtures and exhibited an excellent reusability in repeating separation cycles of water-carbon tetrachloride. Moreover, the SSTM sample displayed great icephobic property including ice-over delay and low ice adhesion. The self-cleaning properties of the SSTM sample were demonstrated using simulated chalk powder that can be easily washed off by injecting water droplets. It also exhibited superior stability in air atmosphere or water over months and great durability under a continuous tap-water flow impacting or abrasion test.

The issues of hydrogen generation and storage have hindered the widespread use and commercialization of hydrogen fuel cell vehicles. It is thus highly attractive, but the design and development of highly active non-noble-metal catalysts for on-demand hydrogen release from alkaline NaBH 4 solution under mild conditions remains a key challenge. Herein, we describe the use of CoP nanowire array integrated on a Ti mesh (CoP NA/Ti) as a three-dimensional (3D) monolithic catalyst for efficient hydrolytic dehydrogenation of NaBH 4 in basic solutions. The CoP NA/Ti works as an on/off switch for on-demand hydrogen generation at a rate of 6,500 mL/(min·g) and a low activation energy of 41 kJ/mol. It is highly robust for repeated usage after recycling, without sacrificing catalytic performance. Remarkably, this catalyst also performs efficiently for the hydrolysis of NH 3 BH 3 .

The Ni–W–S nanoparticles (NPs) were synthesised on Ti mesh through the typical hydrothermal method. The obtained Ti/Ni–W–S was characterised on morphology, composition and electrocatalytic property. It showed good electrocatalytic performance towards glucose oxidation in strong alkali electrolyte, exhibiting the potential application in the field of fuel cell. The excellent electrocatalytic activity of Ni–W–S NPs, the favourable electron transfer between electrode and catalysts, as well as the high conductivity of Ti contributed to its final catalytic performance of Ti/Ni–W–S.

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 .

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.

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.
