Bruno Silveira de Souza is an Associate Professor of Chemistry at the Federal University of Santa Catarina (UFSC), Brazil, where he has been developing research in catalysis and organic reaction mechanisms since 2013. He holds a BSc, MSc and PhD in Chemistry from UFSC, with a specialization in Organic Chemistry. In 2015, he conducted postdoctoral research at the Massachusetts Institute of Technology (MIT), USA, focusing on protein-selective hydrogels.
His research focuses on the development of catalytic systems for sustainable chemical transformations, spanning homogeneous and heterogeneous catalysis. His work encompasses polymer-supported metal catalysts, nanoparticle-based catalytic systems, hydrogenation, C–C coupling reactions, and the conversion of renewable feedstocks. He is also interested in understanding reaction mechanisms through kinetic and mechanistic investigations, linking catalyst structure and composition to catalytic performance and selectivity.
At the Hanse-Wissenschaftskolleg, he will collaborate with researchers at the University of Bremen to investigate nanoporous gold as a catalyst for the liquid-phase oxidation of biomass-derived 5-hydroxymethylfurfural (HMF) into 2,5-furandicarboxylic acid (FDCA), a promising building block for renewable polymers. This research aims to advance the mechanistic understanding of gold catalysis and contribute to the development of more sustainable catalytic processes.
This project explores how nanoporous gold (NPG) can be used as a catalyst to convert a plantbased compound, hydroxymethylfurfural (HMF) into 2,5-furandicarboxylic acid (FDCA), a key building block for producing sustainable plastics. Conducted in collaboration with the University of Bremen and the Hanse-Wissenschaftskolleg, the research focuses on improving understanding of how the reaction works and how to make the process more efficient. FDCA has the potential to replace petroleum-based terephthalic acid in the production of biodegradable plastics, helping to reduce our reliance on fossil fuels. However, current manufacturing methods are costly and energy intensive. NPG’s unique sponge-like structure makes it an ideal material for studying catalytic processes without the influence of supporting materials. This project includes making and analyzing NPG, tracking the reaction process, and evaluating catalyst durability. Ultimately, the goal is to support the development of cleaner, more accessible technologies for turning renewable materials into everyday products, advancing environmental sustainability and equitable access to green innovations.
