Gas selective sensors that are capable of sensing at hot-gas environment increasingly gaining importance for the monitoring combustion and thermal processes releasing NO, NO2 H2 containing hot gases temperatures exceeding 600 °C. Despite some drawbacks, TiO2 is operating as a gas sensor above 500 In this context, Ni-doped TiO2, Co-doped Rh-doped BaTiO3 have been prepared by oxalate coprecipitat...

Although liquid products derived from the pyrolysis of biomass are promising for production petroleum-like hydrocarbon fuels, catalytic burden hydrodeoxygenation must be reduced to achieve feasible upgrading processes. Herein, mild hydrotreating an acid-rich oil (bio-oil) with unusually high total acid number (588 mg KOH/g bio-oil) was performed stabilize low-quality bio-oil. Ru-added TiO2-supp...

The current work focuses on working a comparison between two solar cells made with the combination, n-TiO2/p-CuO, and n-TiO2/p-Cu2O devices. structural, optical, photovoltaic characteristics were detailed. In optical section, measurements for TiO2 (120 nm), CuO (200 Cu2O nm) thin films illustrated, then energy of transition was calculated based Tauc formula each layer. direct gap energies TiO2,...

A series of diketopyrrolopyrrole (DPP) dyes with a terminal phosphonic acid group for attachment to metal oxide surfaces were synthesised and the effect of side chain modification on their properties investigated. The organic photosensitisers feature strong visible light absorption (λ = 400 to 575 nm) and electrochemical and fluorescence studies revealed that the excited state of all dyes provi...

The growth and characterization of an n-GaP/i-GaNP/p+ -GaP thin film heterojunction synthesized using a gas-source molecular beam epitaxy (MBE) method, and its application for efficient solar-driven water oxidation is reported. The TiO2 /Ni passivated n-GaP/i-GaNP/p+ -GaP thin film heterojunction provides much higher photoanodic performance in 1 m KOH solution than the TiO2 /Ni-coated n-GaP sub...
