Nanoparticles and Catalysis
Host: Elisabete R. Silva
Nanoparticles have emerged as remarkable entities in the field of catalysis, revolutionizing our approach to chemical reactions and paving the way for transformative advancements in various industries. [1-2] At the nanoscale, materials exhibit unique properties and reactivity due to their high surface area, size-dependent quantum effects, and tunable surface chemistry. These characteristics have opened up new frontiers in catalysis, enabling more efficient and sustainable processes with broad applications ranging from energy production and environmental remediation to pharmaceuticals and materials science [3-5].
In this exploration of nanoparticles and catalysis, minuscule particles catalyze chemical transformations with unprecedented precision and efficiency is fascinating. [6] The implications are profound, with the potential to address critical challenges facing our world, including environmental pollution, energy sustainability, food technology, and the development of novel therapeutic agents. [7-8]
The applications of nanoparticle catalysis are diverse and far-reaching. From catalytic converters that reduce harmful emissions in automobiles to the production of clean energy through fuel cells and the synthesis of complex molecules in pharmaceutical manufacturing, nanoparticles have left an indelible mark on these industries. Moreover, the emerging field of photocatalysis harnesses the unique properties of nanoparticles to drive chemical reactions using sunlight, offering a sustainable pathway for clean energy and environmental remediation. [9]
In particular, catalytic application of nanostructured materials have strong relevance in the last years, especially in the fight against pathogens, by the inhibition and destruction of important enemies such as viruses, e.g. SARSCoV2 in the last pandemic, emergence new variants or new viruses, but also against bacterial infections and the problem of antibiotic resistance. [10-13] In order for these materials to be as effective as possible, synthetic techniques are crucial.
The development of sustainable systems that reduce the pollution problems or deterioration due to biocorrosion, building constructions or heritage conservation are other important application of nanoparticles. [12]
I will present some of the most recent advances related to the development and application in catalysis of nanobiohybrids, a novel pioneer strategy developed in our lab.
