Editorial

pp. 1

Dra. Elizabeth Rojas García y Dr. Ricardo López Medina

En el presente volumen del Grupo Español de Carbón (GEC) se presentan algunas de las investigaciones que se llevan a cabo en la Universidad Autónoma Metropolitana (UAM) y su colaboración con otras instituciones como el Instituto Politécnico Nacional (ESIQIE-IPN) y el Instituto de Catálisis y Petroleoquímica (ICP)...


Materiales compositos MWCNT@MOF FeBTC para la reducción fotocatalítica de CO2 a combustibles limpios: fotosíntesis artificial
MWCNT@MOF FeBTC composites materials for CO2 photocatalytic reduction to clean fuels: artificial photosynthesis

pp. 2-7

Gloria Pérez-Soreque, Ana M. Maubert-Franco

MWCNT/FeBTC composites materials were synthesized by one-step solvothermal method. The MWCNT were incorporated in situ during composites synthesis. The incorporation of MWCNT to MOF did not show a change in the microcrystalline structure of Fe-BTC...


Bimetallic PdCo and PdFe electrocatalysts for the electrochemical oxidation of formica acid
Catalizadores bimetálicos de PdCo y PdFe para la oxidación electroquímica de ácido fórmico

pp. 8-12

L. Juárez-Marmolejo, S. Pérez-Rodríguez, M. G. Montes de Oca-Yemha, M. Palomar-Pardavé, M. Romero-Romo, A. Ezeta-Mejía, M. V. Martínez-Huerta, M. J. Lázaro-Elorri

Pd, PdCo and PdFe catalysts were prepared by the impregnation method, using sodium borohydride (NaBH4) as the reducing agent and a commercial carbon material (Vulcan XC-72R) as support. The synthesized electrocatalysts were tested for the formic acid oxidation reaction (FAOR) in acid medium (H2SO4 0.5 M)...


Study of the TiO2-graphene system in the generation of hydrogen by means of photocatalytic process in the decomposition of the water molecule without the assitance of sacrifical agents
Estudio del sistema TiO2-grafeno en la generación de hidrógeno por medio de procesos fotocatalíticos en la descomposición de la molécula de agua sin asistencia de agentes de sacrificio

pp. 13-18

Bianca Yazmin Alejandre Zúñiga, José Luis Contreras Larios, Ricardo López Medina

The production of hydrogen by means of the photocatalytic decomposition of the water molecule and its use as an energy vector is one of the most important subjects of study at present, in addition, if in this process a TiO2-graphene catalyst system is used and the use of solar energy without the addition of any sacrificial agent...


Procedure to obtain activated carbons from Pecán nutshell

pp. 19-22

K. Uribe1, A. L. Cortés, J. L. Contreras, L. Nuño1 Berenice Quintana, Ricardo López M. and Tamara Vázquez R.

In the present study, activated carbons were obtained from vegetable Pecán nutshell by physical activation with water vapor, for which an electric furnace and a steam generator were adapted to a tubular rotary pyrolysis reactor where the carbonization of the particles was carried out to proceed immediately to activation...


Recent advances of nanacarbons-MOFs composite materials and their application in photocatalysis
Avances recientes en materiales compositos nanocarbon-MOFs y su aplicación en fotocatálisis

pp. 23-27

E. Rojas-García, A.M. Maubert-Franco, J.M. Barrera-Andrade, E. Albiter, M.A. Valenzuela

This article reviews the recent advances in composite materials based on nanocarbons (graphene oxide (GO), reduced graphene oxide (RGO), carbon nanotubes (CNTs)) and metal-organic frameworks (MOFs) and their application in the photocatalytic degradation of organic-inorganic pollutants and hydrogen photocatalytic production...


Synthesis of carbon nanotubes by acetylene decomposition in MCM-41 and SBA-15 materials modified with Ni, Fe & Co for H2 adsorption

pp. 28-31

L. Soto Soto

The severe pollution problems in urban areas due to the burning of fossil fuels and greenhouse gases, in particular the Metropolitan Zone of the Valley of Mexico, affect the population, the ecosystem and the economy. Recently, higher energy consumption, the decline of conventional reserves and the dramatic increase in the price of gasoline, have activated research to find new sources of energy...


Development of filters based in nanostructured carbon materials for gas separation and purification

pp. 31-32

José Francisco Vivo-Vílches

The aim of the Ph.D. was to develop carbon materials and apply them in processes related to the control of volatile organic compounds (VOCs) emissions from automotive vehicles and the refining and upgrading of biofuels and biogas through selective adsorption. Herein, the use of traditional activated carbons obtained from agricultural wastes (olive stones and pine wood) is complemented by the synthesis of more advanced carbon materials, such as carbon gels obtained...
