A hybrid carbon fiber electrode (CFE) consisting of TiO2 semiconductor photocatalyst and Pt-Ru catalyst has been developed to boost the performance of direct methanol fuel cells (DMFC). These two catalyst nanoparticles are deposited on opposite sides of the carbon fiber paper such that methanol oxidation is carried out catalytically on Pt-Ru and photocatalytically on TiO2 under UV-light irradia...

In this work, the bilayer Pt/TiO2/Co3O4/Pt and single-layer Pt/TiO2/Pt memory devices were fabricated for investigating their resistive switching characteristics. The statistical parameters revealed enhanced performance in device, instance, more centralized operating voltages current, as well lower power consumption. analysis of conductive mechanisms showed that Schottky emission Ohmic responsi...

Designing efficient anode CO-tolerant electrocatalysts is critical in low-temperature fuel cell catalysts fueled either by H2/CO or alcohol. We demonstrate that the incorporation of TiO2 nanocubes (TiO2NCs) on Carbon Vulcan supports, followed synthesis Pt NPs at their surface (Pt/TiO2NCs-C material), led to improvements performance towards electrooxidation carbon monoxide, ethanol, methanol, et...

Hydrogen evolution coupled with the photochemical oxygenation of cyclohexene with water was observed in the system sensitized by Sn(IV)-porphyrin adsorbed on Pt loaded TiO2 nano-particles in aqueous acetonitrile solution upon visible light irradiation.

Octahedral anatase particles (OAPs) were prepared by hydrothermal (HT) reaction of titanate nanowires (TNWs). OAPs were modified with noble metals (Au, Ag, Cu and Pt) by two photodeposition methods: in the absence and in the initial presence of oxygen in the system. Photocatalytic activities for oxidative decomposition of acetic acid and anaerobic dehydrogenation of methanol under UV/vis irradi...

Titanium dioxide (TiO2) with highly exposed {001} facets was synthesized through a facile solvo-thermal method and its surface was decorated by using reduced graphene oxide (rGO) sheets. The morphology and chemical composition of the prepared rGO/TiO2 {001} nanocomposite were examined by using suitable characterization techniques. The rGO/TiO2 {001} nanocomposite was used to modify glassy carbo...

This study investigated ageing-resistant properties of carboxyl-terminated polyester (polyethylene glycol terephthalate) composites modified with nanoscale titanium dioxide particles (nano-TiO2). The nano-TiO2 was pretreated by a dry coating method, with aluminate coupling agent as a functional grafting additive. The agglomeration resistance was evaluated, which exhibited significant improvemen...

The catalytic oxidation of VOCs is widely acknowledged as the most available technology to reduce air pollution. Among catalysts for VOCs, 1 wt%-Pt/TiO2 using metal a doping element have shown amazing potential in many fields. However, achieving high performance at relatively low temperatures based on activation molecules still formidable challenge owing activity being highly dependent temperat...
