Atomic catalyst unlocks the hidden value of plant waste
Researchers have developed a single-atom ruthenium catalyst that efficiently breaks down lignin, a complex plant waste material. This breakthrough allows for the conversion of agricultural and forestry waste into valuable aromatic chemicals.
Why it matters
It provides a sustainable pathway to replace petroleum-based chemicals with renewable biomass, advancing green manufacturing.
Lignin gives plants much of their structural strength and represents the largest renewable source of aromatic chemicals found in nature. It can make up a substantial share (up to 35%) of waste biomass from agriculture and forestry. Yet lignin's complicated molecular structure makes it notoriously difficult to break apart efficiently, which has limited its potential use in sustainable manufacturing.
In a study published in ACS Catalysis , an international team that included Dr. Christopher Parlett, Xinyue Zhou, and Yutao Jiang from the Department of Chemical Engineering developed a highly efficient "single-atom catalyst." The researchers also determined, at the molecular level, how the catalyst breaks the strong chemical bonds that help hold lignin together.
