Project Title (1): Synthesis and characterization of fullerene and carbon nano-onion derivatives for diverse purposes: from catalytic to biological applications
Project Description (1): Carbon based nanomaterial have shown to have enhanced catalytic properties for several electrochemical reactions (HER, ORR, OER, NRR) and have proved to act efficiently against several diseases. It was recently shown by our group that fullerene derivatives can act against HIV in the late stages of the cycle, inhibiting further infection to other cells. On the other hand, several reports have shown that fullerene derivatives and other carbon-based materials can efficiently prevent and treat Alzheimer’s disease. In this project we are focused on the rational design, synthesis and characterization of fullerene and carbon nano-onions to be used as nanocatalysts and also as potential agents against HIV and Alzheimer’s disease.
Project Title (2): Perovskite Solar Cells
Project Description (2): In less than a decade Perovskite Solar Cells have experienced an incredible rise in power conversion efficiencies (PCE) starting from 3.8% in 2009 to 25.2% in 2019. Due to their electron transporting properties and low-cost deposition techniques, fullerene derivatives are the most attractive semiconductors used as electron transporting materials (ETMs) in PSCs. In this project we synthesize, characterize new fullerene derivatives and use them as ETMs in inverted and regular PSCs.
Project Title (3): Comprehensive study of the reactivity of Higher Fullerenes
Project Description (3): Fullerenes have always been an attractive allotrope of carbon due to their amazing properties, mainly C60 and C70 due to their easy of obtention and good yields. Intensive studies about their reactivity have been done since their discovery. Nevertheless, there is still a lot of unexplored field when it comes to higher fullerenes. In this project, we study the reactivity and electrochemistry of one of the most abundant higher fullerenes, C90 and C100.
Project Title (4): Fullerene based MOFs
Project Description (4): Metal–organic frameworks (MOFs) are compounds consisting of metal ions or clusters coordinated to organic ligands to form one-, two-, or three-dimensional structures. These are porous material capable of storage different gases, in particular, hydrogen. On the other hand, fullerenes are also known for storage hydrogen. Therefore, in this project we are working on the synthesis of fullerene derivatives with a very well define regioselectivity in order to use them to create a fullerene-based MOF with an enhanced hydrogen storage capability.
