Five selected publications
  • Margarida M. Antunes, Patrícia Neves, Auguste Fernandes, Sérgio Lima, Andreia F. Silva, Maria Filipa Ribeiro, C. M. Silva, Martyn Pillinger, Anabela A. Valente, “Bulk and composite catalysts combining BEA topology and mesoporosity for the valorisation of furfural”, Catalysis Science & Technology 6 (2016) 7812-7829. DOI: 10.1039/C6CY00223D. IF=5.81.

In this work, the materials synthesis and catalytic studies were carried out by M. M. A. A collaboration with a different institution was required for acid properties measurements, which helped understand the influence of material properties on the catalytic reactions. Improved selectivity of the bioproducts was managed by using materials, which were strategically prepared via impregnation of nanocrystaline Zr-Beta into a TUD-1 type mesoporous matrix, or, alternatively, using a mesoporous version of Zr-beta. The materials enhanced the acid sites accessibility and facilitated internal diffusion.

IF=8.87.

 

This work is an example where complex chemical reactions are integrated in one-pot synthesis, using a multifunctional catalyst. The idea was to prepare eco-friendly heterogeneous catalysts in terms of composition (e.g. zirconium instead of tin), and an inorganic mesoporous oxide matrix of the type TUD-1 was used for the incorporation of Zr, being advantageously prepared via a green, low-cost and non-surfactant templating routes.

IF=7.61.

This work is an example of collaborations at an international level, involving institutions from three different countries. The idea was successful in obtaining biofuel additives (alkyl furfuryl ethers or levulinate esters) directly from furfural in one-pot. Bifunctional catalysts possessing Al and Sn enabled the reduction and acid reactions. The catalysts were prepared via up-scalable post-synthesis modifications of commercially available precursor materials.

This work was internationally selected by J. Evans for Technology news, “Graphene catalyst: Wonder material makes wonder biofuel catalyst”, Biofuels, Bioproducts and Biorefining, 8 (2014) 301. DOI: 10.1002/bbb.1492. It involved three different groups of CICECO. It deals with carbon-based materials. The carbon materials have the advantages of being metal-free, stable, cheap, and recyclable, contributing for green and sustainable catalytic transformations. A partially reduced graphene oxide prepared via functionalisation on both sides of the carbon sheets, and was very active, selective and stable for the production of alkylfufuryl ethers and ethyl levulinate from Hmf.

Review in which I was a co-author. This review followed a work in collaboration with the company Merck. It focused on ionic liquids used as catalyst and/or solvents for the acid catalysed hydrolysis/dehydration of saccharides to furanic aldehydes, due to their ability for solubilizing polysaccharides (important for process intensification).
