Photoelectrochemical (PEC) urea splitting is of great significance for wastewater remediation and hydrogen production with low energy consumption simultaneously. Nickel hydroxides as electrocatalysts have been widely investigated electrolysis. However, it an open question how to synthesize highly catalytic Ni(OH)2 the PEC splitting. Herein, we take advantage instability metal–organic frameworks...

Mesoporous nanosized titania films modified with Co2+, Ni2+, Mn3+, and Cu2+ ions have been produced by templated sol-gel method and characterized by optical spectroscopy, X-ray diffraction (XRD), and Brunauer, Emmett, and Teller (BET) surface area measurement. Band gap energy and the position of flat band potentials were estimated by photoelectrochemical measurements. The films doped with trans...

Ni0.9Fe0.1 alloy-supported solid oxide fuel cells with NiTiO3 (NTO) infiltrated into the cell support from 0 to 4 wt.% are prepared and investigated for CH4 steam reforming activity and electrochemical performance. The infiltrated NiTiO3 is reduced to TiO2-supported Ni particles in H2 at 650 °C. The reforming activity of the Ni0.9Fe0.1-support is increased by the presence of the TiO2-supported ...

The study compares the photocatalytic behavior of TiO2, NiO-TiO2, and Ni-NiO-TiO2 photocatalysts in hydrogen production from methanol–water solution. TiO2 NiO-TiO2 with theoretical NiO loading 0.5, 1.0, 3.0 wt. % were prepared by sol–gel method. partial reduction at 450 °C. showed significantly higher than photocatalysts. structural, textural, redox, optical properties all studied using XRD, SE...

In the present study, a nanocrystalline Ni-Fe matrix with reinforced TiO2 nanoparticles as functional nanocomposite material was fabricated by pulsed current electroforming in UV-LIGA (lithography, electroplating, and molding). The influences of on deposition were also investigated using scanning electron microscopy, transmission vitro cytotoxicity assay. It found that 5 wt.% showed smooth surf...
