The microscopic sponge developed at RMIT is a new type of ultra-efficient catalyst that turns complex molecules into raw materials with an unprecedented degree of control over the output.

“Catalysts have previously been developed that can perform multiple simultaneous reactions, but these approaches offer little control over the chemistry and tend to be inefficient and unpredictable,” co-lead investigator Professor Karen Wilson explained in a press release.

“Our bio-inspired approach looks to nature’s catalysts – enzymes – to develop a powerful and precise way of performing multiple reactions in a set sequence. It’s like having a nanoscale production line for chemical reactions – all housed in one, tiny and super-efficient catalyst particle,” he continued.
