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, ...
Citrate adsorption on gold: Understanding the shaping mechanism of nanoparticles

Gisbert-González, José M.; Cheuquepán, William; Ferre Vilaplana, Adolfo; Herrero, Enrique; Feliu, Juan M. (Elsevier, 2020-10-15)

[EN] Advanced applications of colloidal nanoparticles (NPs) become to depend on their specific shape, which is controlled by the adsorption behavior of the capping agent involved in their synthesis. To understand the way ...
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 ...
Glutamate adsorption on gold electrodes at different pH values

Gisbert-González, José M.; Ferre Vilaplana, Adolfo; Herrero, Enrique (Elsevier, 2021-09-01)

[EN] Advanced medical applications of gold nanoparticles can use amino acids as surface modifiers. For this reason, understanding the adsorption of amino acids on gold is crucial to improve these applications. Here, the ...
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 ...
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 ...
Why Methanol Electro-oxidation on Platinum in Water Takes Place Only in the Presence of Adsorbed OH

Mekazni, Dalila S.; Arán-Ais, Rosa; Ferre Vilaplana, Adolfo; Herrero, Enrique (American Chemical Society, 2022-02-04)

[EN] Untangling the mechanism of the methanol electro-oxidation on platinum in water as a model reaction is essential to optimize fuel cells using alcohols as fuel. Recent experiments unexpectedly suggested that this ...
Why nitrogen favors oxygen reduction on graphitic materials

Ferre Vilaplana, Adolfo; Herrero, Enrique (Royal Society of Chemistry, 2019-09-01)

[EN] Nitrogen-doped graphitic materials as promising catalysts for the oxygen reduction reaction in fuel-cells have been mainly investigated under the graphitic versus pyridinic nitrogen-dopant dichotomy approach. However, ...
Why the activity of the hydrogen oxidation reaction on platinum decreases as pH increases

Briega-Martos, Valentín; Ferre Vilaplana, Adolfo; Herrero, Enrique; Feliu, Juan M. (Elsevier, 2020-09-10)

[EN] Platinum is a very effective electrode for the hydrogen evolution and oxidation reactions (HER/HOR) in acidic media. However, the activity for the HOR on platinum falls two orders of magnitude from acidic to alkaline ...
