We report on the optimized fabrication and electrochemical properties of ternary metal oxide (Ti-Mo-Ni-O) nanoparticles as supercapacitor electrode materials. The structural, morphological, elemental composition fabricated Ti-Mo-Ni-O
To date, most studies on the fabrication and development of photoelectrodes for solar-fuel generation have been based simple binary systems with limited success. However, ternary not explored extensively although they can offer more possibilities band gap alignment tuning that allow efficient photoelectrochemical systems. Herein, we report growth a novel oxide photoanode material composed self-ordered, vertically oriented nanotube arrays titanium-molybdenum-nickel mixed films via anodization...
Abstract The charge storage performance of metal oxides as electrochemical supercapacitor electrodes is limited by their poor conductivity and operating potential window. Herein, we report on the oxygen‐vacancy engineering Ti−Mo−Ni−O nanotubes via hydrogen annealing to boost capacitive performance. Hydrogen treatment resulted in 110% increase specific capacitance compared air‐annealed counterpart with excellent stability over 3700 cycles an exceptional retention 99%. observed enhancement can...
Upon the tremendous spread of coronavirus, there is a need to develop biodegradable, multifunctional, antiviral masks that can be safely used without polluting environment as conventional surgical do. In this study, three-layered mask filter designed and fabricated. The first two layers contain electrospun polyamide with dispersed nanoparticles (NPs) TiO
Rutin, a flavonoid phytochemical compound, plays vital role in human health. It is used treating capillary fragility and has anti-Alzheimer, anti-inflammatory, antioxidant effects. In this study, Ti-Mo-Ni-O nanotubes (NTs) were used, for the first time, an unprecedented plant biotechnology application, wherein vitro Philodendron shoots (Philodendron erubescens) known as “Imperial Red” targeted rutin accumulation. The responses accumulation of evaluated treated erubescens (P. using 5.0 mg/L...
Abstract Point defects play important and crucial roles in the design of high performance photocatalysts. We report on electrochemical fabrication black Ti−Mo‐Ni−O nanotubes as a promising electrode material for solar‐assisted water splitting. The ternary catalyst was annealed hydrogen atmosphere to induce point enhance its conductivity, charge carriers density, performance. effect annealing duration nanotube films investigated. hydrogen‐annealed showed enhanced optical characteristics...
