Editorial

pp. 1

Sónia Carabineiro

It is a pleasure to act as guest editor of this special issue of Boletin del Grupo Español del Carbono (BGEC) dedicated to the recent research carried out on carbon materials in Portugal...


El Grupo Portugués del Carbono (Grupo do Carbono @ SPQ)
The Carbon Group of the Portuguese Chemical Society (Grupo do Carbono @ SPQ)

pp. 2-3

José Luis Figueiredo

The Carbon Group of the Portuguese Chemical Society (Grupo do Carbono@SPQ) was set up in September 2015, upon the request of a number of members of Sociedade Portuguesa de Química (SPQ) from the Universities of Porto, Aveiro, Coimbra, Lisboa, Nova de Lisboa and Évora, and also from the Polytechnic Institute of Bragança...


Materiales de carbono @LCM: una actualización
Carbon materials @ LCM: an update

pp. 4-11

José Luis Figueiredo

LCM's main achievements towards the development of carbons for catalysis, energy and environmental applications were previously reviewed in Boletin nº 39 (March 2016). In the present report, we will provide an update, focusing only on our most recent work...


Hybrid/Doped Carbon-Based (Nano)materials for Advanced Applications: Eco-Sustainable Catalysis, Biomass Valorization, Energy Technologies & Smart Devices

pp. 12-26

Cristina Freire, Andreia F. Peixoto, Diana M. Fernandes, Bruno Jarrais, Marta Nunes and Ruben Ramos

Carbon-based (nano)materials are remarkable building blocks that have been boosting innovation in a multitude of advanced applications, ranging from Catalysis and Environment to Energy and Smart Technologies...


The role of carbon materials as supports for transition metalbased catalysts

pp. 27-32

Luísa M.D.R.S. Martins

In this communication, a brief overview of the studies developed by the Coordination Chemistry and Catalysis (CCC) Group of Centro de Química Estrutural (Instituto Superior Técnico, Universidade de Lisboa) related to the use of carbon materials as catalysts supports is presented...


Acid-chars - versatile materials for adsorption and catalysis

pp. 33-38

Ana Paula Carvalho & Ana Sofia Mestre

In this communication an overview of the most recent studies developed in the Adsorption and Adsorbent Materials Group related with the use of acid mediated carbonization (AMC) to prepare carbon materials is presented. The chars obtained by this methodology – acid-chars – have been explored for different purposes...


Simple routes for the functionalization of carbon nanoparticles and potencial applications

pp. 39-43

María C. Paiva1 and M. Fernanda Proença

The interest in the field of carbon materials started for M.C. Paiva in the early nineties with the emerging ideas for the development of carbon fibers that could reach the automotive industry. After a brief investigation on the surface characterization of vapor grown carbon fibers produced by J. L. Figueiredo research group, the focus turned into pitch and PAN-based carbon fibers...


A short review on carbon-based nanomaterials and their hybrids

pp. 44-54

Bohdan Kulyk, Alexandre Faia Carvalho, Nuno Santos, Antonio José Fernandes, Florinda Mendes Costa

A wide range of carbon allotropes exists, each with different properties and characteristics that make them appealing for various practical applications. In this brief review, our work on carbon-based nanomaterials is presented. Particular attention is given to hybrid materials, characterized by a simultaneous growth of different carbon allotropes...


An Overview of CVD Diamond Growth on Ceramics and Synthesis of CNTs at the University of Aveiro

pp. 55-65

Eduardo Silva, Sérgio Pratas, aneeta Jaggernauth, Ricardo Silva, Miguel Neto, Filipe Oliveira, Rui Silva

The Carbon and Ceramic Composites Group from the University of Aveiro has been active for almost 25 years, working mostly on applied research. Led by Professor Rui Silva, it all started with a study about the wear properties of tungsten carbide coated CVD diamond...


Bamboo-Like Carbon fibers growth mechanism

pp. 66-69

Luis Sousa Lobo

Bamboo-like growth behavior of carbon fibers is explained. There is a requirement to have this type of growth: to operate above the Tammann temperature of the catalyst. The metal nanoparticle can change shape during reaction (sintering-like behavior) so that CNT growth adjusting geometry...


Preparation of submicron carbon fibers from lignocellulosic waste for energy and environmental applications

pp. 70-72

Francisco José García Mateos

The objective of this PhD Thesis was the preparation of advanced fibrous carbon materials to be used in energy and environmental applications. For this purpose, coaxial electrospinning technique, a simple and versatile method, was used to prepare submicron diameter fibers. Alcell lignin was used as carbon precursor for the preparation of carbon fibers. In this Thesis work...


Pt-Sn Electrocatalysts for the ethanol oxidation reaction

pp. 73-75

Rubén Rizo

Electrochemical energy conversion and storage play essential roles in addressing the global energy challenge. In particular, direct ethanol fuel cells (DEFC) represent an attractive alternative to resources based on fossil fuel combustion for portable power generation. Ethanol is an eco-friendly and renewable fuel (naturally available in large quantities from biomass), and its complete oxidation to CO2 and H2O would lead to high energy densities...
