185 Nm Photoreduction of CO2 to methane by water. Influence of the Presence of a Basic catalyst

Sastre Calabuig, Francesc; Corma Canós, Avelino; García Gómez, Hermenegildo (American Chemical Society, 2012-08-29)

Photolysis of CO2 at 185 nm using a Hg lamp in the presence of H-2 or H2O leads to the formation of CH4 (after an induction period) and a lesser amount of CO. Using H-2 gas as reducing agent, up to 40% conversion was ...

Sastre Calabuig, Francesc (Universitat Politècnica de València, 2012-01-24)

La Adición de Michael de los compuestos activos de metileno para la obtención de compuestos carbonílicos alfa, beta-insaturados es una reacción general empleada en síntesis orgánica. En el presente trabajo se ha encontrado ...
Complete Photocatalytic Reduction of CO2 to Methane by H2 under Solar Light Irradiation

Sastre Calabuig, Francesc; Puga, Alberto V.; Liu, Lichen; Corma Canós, Avelino; García Gómez, Hermenegildo (American Chemical Society, 2014-05-14)

Nickel supported on silica-alumina is an efficient and reusable photocatalyst for the reduction of CO2 to methane by H-2, reaching selectivity above 95% at CO2 conversion over 90%. Although NiO behaves similarly, it undergoes ...
Conversion of Methane into C1 Oxygenates by Deep-UV Photolysis on SolidSurfaces: Influence of the Nature of the Solid and Optimization of PhotolysisConditions

Sastre Calabuig, Francesc; Fornes Seguí, Vicente; Corma Canós, Avelino; García Gómez, Hermenegildo (Wiley-VCH Verlag, 2012)

[EN] Deep-UV photolysis (either 165 or 185 nm) of surface hydroxy groups leads to homolytic O H bondcleavage with the generation of oxyl radicals that can initiate the room-temperature radical-chain methane activation. ...
Deep UV photocatlytic activation of ethane on silica surfaces

Sastre Calabuig, Francesc; Corma Canós, Avelino; García Gómez, Hermenegildo (Elsevier, 2012-11-30)

Deep UV photolysis (165 or 185 nm) of surface silanol groups leads to the homolytic Osingle bondH bond breaking, generating silyloxyl radicals and hydrogen atoms. Silyloxyl radicals are able to activate ethane through ...

Photocatalytic water gas shift using visible or simulated solar light for the efficient, room-temperature hydrogen generation

Sastre Calabuig, Francesc; Oteri, Marica; Corma Canós, Avelino; García Gómez, Hermenegildo (Royal Society of Chemistry, 2013-07)

Gold nanoparticles supported on P25 TiO2 act as highly efficient photocatalysts for promoting the simultaneous H2O reduction to H-2 and CO oxidation to CO2. This photocatalytic process can be performed using simulated solar ...
Selective room-temperature transformation of methane to C1 Oxygenates by deep UV Photolysis over zeolites

Sastre Calabuig, Francesc; Fornes Seguí, Vicente; Corma Canós, Avelino; García Gómez, Hermenegildo (American Chemical Society, 2011-11)

[EN] Methane can directly be transformed into liquid C 1 oxygenated products with selectivities above 95% at 13% conversion by deep UV photocatalysis, in the presence of H 2O and air. Pure silica zeolites, and more ...
Visible-ligth photocatalytic conversions of carbon monoxide to methane by nickel (II) oxide

Sastre Calabuig, Francesc; Corma Canós, Avelino; García Gómez, Hermenegildo (Wiley-VCH Verlag, 2013-12-02)

Solar Fuels: Different n- and p-type semiconductors have been investigated for sustainable solar fuel production. p-Type semiconductors, such as NiO, Fe3O4, Co3O4, and CuO, are able to reduce carbon monoxide by water or ...
