Catalysis is used in almost all industries. For instance, about 80% of chemical products are manufactured using catalysis. Catalysis is key for sustainable social development since it ensures more efficient use of natural resources. In this regard, nanocatalysts (catalysts with nano sized particles) have attracted tremendous interest in various fields due to their extraordinary efficiency as compared to conventional catalysts. We recently showed that, the combination of ultrasmall nanoparticles and pseudo-single atoms of gold (Au) and fibrous nanosilica (KCC-1) catalyzes the transformation of organosilanes to silanols, with a turn over number of approximately half a million. That means, just one mole of Au converts 5,91,000 moles reactant to product.
