New composites consisting of decahedral anatase particles exposing {0 0 1} and {1 facets coupled with accordion-like layered Ti3C2 boosted photocatalytic activity towards phenol carbamazepine degradation were investigated. The photocatalysts characterized X-ray diffraction (XRD), diffuse reflectance spectroscopy (DR/UV–Vis), Brunauer-Emmett-Teller (BET) specific surface area, Raman spectroscopy, scanning electron microscopy (SEM), paramagnetic resonance (EPR) emission luminescence decay...
Abstract This work presents results on structuring of thin gold/silver (AuAg) composite film by laser pulses with different pulse durations. Laser systems that generate millisecond (50 ms), nanosecond (15 ns), picosecond (10 ps), and femtosecond (100 fs) are used in the experiments. The wavelength is 1064 nm for ms, ns, ps regime 800 one. metal films deposited pulsed deposition technique quartz substrates using pulses. surface morphologies induced variation processing parameters as duration...
This work presents results on nanosecond laser ablation of a titanium (Ti) plate immersed in liquid medium using the fundamental wavelength (1064 nm) Nd:YAG system. The radiation was focused target surface as scanning accomplished by an XY translation stage. processing Ti targets took place two organic liquids—liquid paraffin and diesel oil. morphology structured surfaces structure phase composition samples were studied; their dependences parameters are discussed. With both media used, crack...
Titanium dioxide nanotubes gain considerable attention as a photoactive material due to chemical stability, photocorrosion resistance, or low-cost manufacturing method. This work presents scalable pulsed laser modification of TiO2 resulting in enhanced photoactivity system equipped with motorized table, which allows for modifications both precisely selected and any-large sample area. Images obtained from scanning electron microscopy along Raman UV–vis spectra laser-treated samples good...
Electrochemical anodization is regarded as a facile and easily scalable fabrication method of titania nanotubes (TiO2NTs). However, due to the extended duration calcination further modifications, much faster alternatives are highly required. As response growing interest in laser modification nanotube arrays, comprehensive investigation pulsed-laser irradiation its effect onto TiO2NT properties has been carried out. The impact surface being placed at different angles respect beam was studied...
Abstract The detection of glucose at low concentrations using electrochemical sensors is great importance due to the possibility different human body fluids than blood, such as e. g. urine, saliva, sweat or tears. interest behind those biofluids related their utility in non‐invasive sugar determination. In this work, we present flexible, fully biocompatible electrode material based on Au nanoparticles immobilized onto titanium dimples. Au−Ti heterostructures were obtained via anodization...
Au-Cu nanostructures offer unique optical and catalytic properties unlike the monometallic ones resulting from specific interaction. Among others, they have ability to exhibit surface plasmon resonance, electrochemical activity towards oxygen hydrogen evolution reaction (OER, HER) as well improved photoresponse in relation monometalic but those depend highly on substrate where bimetallic structures are immobilized. In this work, gold-copper mosaics over conducting structured titanium were...
In this study, Ti3C2Tx underwent laser treatment to reshape it, resulting in the formation of a TiO2/Ti3C2Tx heterojunction. The interaction with light induced spherical TiO2 composed an anatase-rutile phase on surface. Such heterostructure was loaded over titania nanotube (TNT) layer, and surface area enhanced through immersion TiCl4 solution followed by thermal treatment. Consequently, photon-to-electron conversion efficiency exhibits 10-fold increase as compared bare TNT. Moreover, for...
