An Aza-Fused pi-Conjugated Microporous Framework Catalyzes the Production of Hydrogen Peroxide

Briega-Martos, V.; Ferre Vilaplana, Adolfo; de la Peña, Alejandro; Segura, J.L.; Zamora, F.; Feliu, Juan; Herrero, Enrique (American Chemical Society, 2017-02-03)

[EN] In order to produce hydrogen peroxide in small-scale electrochemical plants, selective catalysts for the oxygen reduction reaction (ORR) toward the desired species are required. Here, we report about the synthesis, ...
Charge transfer, bonding conditioning and solvation effect in the activation of the oxygen reduction reaction on unclustered graphitic-nitrogen-doped graphene

Ferre Vilaplana, Adolfo; Herrero, Enrique (Royal Society of Chemistry, 2015-05)

The monodentate associative chemisorption of molecular oxygen on unclustered graphitic-nitrogen-doped graphene requires two nitrogen dopants per activated molecule. Significant charge transfers fromregions corresponding ...
Formic acid oxidation on platinum electrodes: A detailed mechanism supported by experiments and calculations on well-defined surfaces

Ferre Vilaplana, Adolfo; Perales, Juan Víctor; Buso-Rogero, Carlos; Feliu, Juan; Herrero, Enrique (The Royal Society of Chemistry, 2017-11-07)

[EN] In spite of the fact that the formic acid oxidation reaction on electrode surfaces has been extensively investigated, a detailed mechanism explaining all the available experimental evidence on platinum has not been ...
On the electrochemical properties of platinum stepped surfaces vicinal to the (100) pole. A computational study

Ferre Vilaplana, Adolfo; Gisbert, Ruben; Herrero, Enrique (Elsevier, 2014-04-10)

DFT studies on platinum stepped surfaces have been carried out in order to understand the differences in the electrochemical behavior between the surfaces with (111) and (100) terraces. Thus, adsorption energies of different ...
Oxidation mechanism of formic acid on the bismuth adatom-modified Pt(111) surface

Perales Rondón, Juan Victor; Ferre Vilaplana, Adolfo; Feliu, Juan; Herrero, Enrique (American Chemical Society, 2014-09-14)

In order to improve catalytic processes, elucidation of reaction mechanisms is essential. Here, supported by a combination of experimental and computational results, the oxidation mechanism of formic acid on Pt(111) ...
The role of formic acid/formate equilibria in the oxidation of formic acid on Pt(111)

Busó-Rogero, Carlos; Ferre-Vilaplana, Adolfo; Herrero, Enrique; Feliu, Juan M. (Elsevier, 2019-01)

[EN] The formic acid oxidation reaction has been studied in concentrated perchloric acid solutions (up to 9.14M (60%)) on the Pt (111) surface to explore the relationships between interfacial properties and kinetics. It ...
Understanding the chemisorption-based activation mechanism of the oxygen reduction reaction on nitrogen-doped graphitic materials

Ferre Vilaplana, Adolfo; Herrero, Enrique (Elsevier, 2016-06-20)

[EN] To optimize nitrogen-doped graphitic materials as metal-free catalysts for the oxygen reduction reaction mechanisms have to be better understood. Here, the role played by pyridinic nitrogen-dopants in the chemisorption-based ...
Understanding the effect of the adatoms in the formic acid oxidation mechanism on Pt(111) electrodes

Ferre Vilaplana, Adolfo; Perales Rondón, Juan Víctor; Feliu, Juan M.; Herrero, Enrique (American Chemical Society, 2015-02)

The engineered search for new catalysts requires a deep knowledge about reaction mechanisms. Here, with the support of a combination of computational and experimental results, the oxidation mechanism of formic acid on ...
Why Citrate Shapes Tetrahedral and Octahedral Colloidal Platinum Nanoparticles in Water

Gisbert-González, J.M.; Feliu, Juan; Ferre Vilaplana, Adolfo; Herrero, Enrique (American Chemical Society, 2018-08-23)

[EN] The performance of many advanced catalytic systems depends not only on the size and composition but also on the specific shape of the metal nanoparticles (NPs) from which they are assembled. In turn, the shape of ...
