Influence of Pt particle size and reaction phase on the photocatalytic performances of ultradispersed Pt/TiO2 catalysts for hydrogen evolution
(2019-07-01)
Article
Restricted access - publisher's policyPt/TiO2 photocatalysts were prepared by incipient wetness impregnation followed by oxidative and/or reductive thermal treatments. By varying the TiO2 form (commercial P25 and P90, and homemade shape-controlled), the Pt ... -
Dynamic reorganization of bimetallic nanoparticles under reaction depending on the support nanoshape: the case of RhPd over ceria nanocubes and nanorods under ethanol steam reforming
(2019-04-05)
Article
Restricted access - publisher's policyBimetallic catalysts exhibit high performance compared to that of their monometallic counterparts in a wide range of catalytic reactions. Both geometric and electronic phenomena yield unique properties that cannot be ... -
Carbonation of high-calcium fly ashes and its potential for carbon dioxide removal in coal fired power plants
(2018-08)
Article
Restricted access - publisher's policyCarbonation of industrial wastes rich in earth-alkali oxides is found to have a significant potential for CO2 sequestration. This process opens new perspectives not only for carbon dioxide mitigation, but also for the ... -
Effect of TiO 2 nanoshape on the photoproduction of hydrogen from water-ethanol mixtures over Au 3 Cu/TiO 2 prepared with preformed Au-Cu alloy nanoparticles
(2019-07-05)
Article
Restricted access - publisher's policyA series of TiO2 nanoshapes (microurchins, nanobelts, nanowires, microrods and nanotubes) were prepared and decorated with preformed nanoparticles of Au-Cu alloy (Au:Cu¿=¿3:1 molar, 1¿wt.% metal content). The resulting ... -
Catalytic ammonia decomposition for hydrogen production on Ni, Ru and Ni–Ru supported on CeO2
(2019-05-13)
Article
Restricted access - publisher's policyCeria-supported Ni, Ru and NiRu catalysts have been tested in the catalytic decomposition of ammonia to yield hydrogen and their performance in long-term tests has been compared to alumina-supported Ni and Ru samples. The ... -
Utilization of high-calcium fly ashes through mineral carbonation: the cases for Greece, Poland and Spain
(Elsevier, 2019-07)
Article
Restricted access - publisher's policyLimited utilization possibilities of high–calcium fly ashes (HCFA) are a serious issue not only in Europe, but also worldwide. The properties of such waste from coal-fired power plants could be conveniently treated in order ... -
Oxidation by H2O(g) in the presence of H2(g) of UO2 doped with Pd nanoparticles
(2018-09-28)
Article
Restricted access - publisher's policyThis work studies the influence of epsilon particles and metallic precipitates, simulated through the deposition of Pd nanoparticles on non-irradiated UO2, on the oxidation of the spent nuclear fuel (SNF). The presence of ... -
A nafion film cover to enhance the analytical performance of the CuO/Cu electrochemical sensor for determination of chemical oxygen demand
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-02-06)
Article
Open AccessWe modified and evaluated the performance of a CuO/Cu electrochemical electrode for chemical oxygen demand (COD) determination by covering it with a Nafion (Nf) film. The resulting modified CuONf/Cu electrode sensor was ... -
Effect of Ce and Mn co-doping on photocatalytic performance of sol-gel TiO2
(2019-02-01)
Article
Restricted access - publisher's policyCo-doped titanium dioxide was synthesized by doping with manganese (Mn) and cerium (Ce) through a sol-gel method for the degradation of diclofenac (DCF). The synthesized products were successfully characterized by X-ray ... -
A comparative study of water-immiscible organic solvents in the production of furfural from xylose and birch hydrolysate
(2019-04-25)
Article
Restricted access - publisher's policyFurfural (FUR) was produced from xylose using a biphasic batch reaction system. Water-immiscible organic solvents such as isophorone, 2-methyltetrahydrofuran (2-MTHF) and cyclopentyl methyl ether (CPME) were used to promptly ... -
Partial oxidation of methane to syngas using Co/Mg and Co/Mg-Al oxide supported catalysts
(2018-04-03)
Article
Restricted access - publisher's policyPartial oxidation of methane (POM) was studied over a series of Co/Mg-Al catalysts. Various commercial hydroxides with different Mg/Al ratios were used as precursors of the oxides employed as catalytic supports, as well ... -
Tin diselenide molecular precursor for solution-processable thermoelectric materials
(2018-11-06)
Article
Restricted access - publisher's policyIn the present work, we detail a fast and simple solution-based method to synthesize hexagonal SnSe2 nanoplates (NPLs) and their use to produce crystallographically textured SnSe2 nanomaterials. We also demonstrate that ...
