The team have developed a more efficient and simpler process that – when combined with flow chemistry - does away with the need to filter out catalysts.
It was the first successful example of a combined catalyst and flow reactor technology that could make the leap from the laboratory to industry.
"Before now, making catalytic chemical reactions faster and more scalable has been a challenge, but this smarter process, that gives a better result in a short period, lends itself to more efficient scale up," Dr Gardiner said.
Normally in chemical processing a powdered metal catalyst is added to a mixture to ensure a chemical reaction takes place.
The catalyst is then removed at the end – an often tedious, time-consuming and costly task.
They were then placed inside the flow reactor, allowing reactions to occur without the catalyst leaching into the product.
"This breakthrough means that any industry doing complex catalyst processes can now use a process that is smarter, faster and more efficient," CSIRO Research Director for Advanced Fibres and Chemicals Dr John Tsanaktsidis said
"We've developed a method for chemical processing that combines all the benefits of flow chemistry with a much simpler way of using metal catalysts in them, reducing the number of steps that need to be taken."
