A team of researchers led by Marc Porosoff at the University of Rochester has made a breakthrough in using tungsten carbide as a more sustainable and cost-effective catalyst for petrochemical processes. By precisely controlling the atomic structure of tungsten carbide, the team has found that a specific phase, β-W₂C, can be as effective as platinum in converting carbon dioxide and breaking down plastic waste, without the high costs and supply constraints of precious metals.

Why it matters

The petrochemical industry's reliance on scarce and expensive precious metal catalysts has long been a challenge for sustainable and affordable production of everyday materials. This discovery of a viable alternative in tungsten carbide could revolutionize the industry, reducing costs and environmental impact.

The details

Porosoff's team developed a precise method called temperature-programmed carburization to manipulate the atomic structure of tungsten carbide, optimizing its catalytic performance. They found that certain phases of tungsten carbide, like β-W₂C, are more stable and effective as catalysts compared to others. This breakthrough allows tungsten carbide to potentially match the efficiency of platinum in key processes like converting carbon dioxide and hydrocracking plastic waste.

  • The research was published in April 2026 in the journal ACS Catalysis.
  • The team's work on precise temperature measurement in chemical reactors was published in EES Catalysis.

What they’re saying

“The key to tungsten carbide's effectiveness lies in its atomic arrangement, or phases. The lack of understanding of tungsten carbide's surface structure has been a major hurdle.”

— Sinhara Perera, PhD student

“Accurate temperature measurement is vital for controlling chemical reactions. Traditional measurements can be off by up to 100 degrees Celsius, impacting the reproducibility of catalytic studies.”

— Andrea Pickel, Visiting professor

What’s next

The team's research, funded by institutions like the Sloan Foundation and the National Science Foundation, aims to further refine the use of tungsten carbide as a sustainable and cost-effective catalyst in the petrochemical industry. Future studies will focus on scaling up the production and testing the long-term stability of the β-W₂C phase.

The takeaway

This breakthrough in tungsten carbide catalysts could revolutionize the petrochemical industry, reducing its reliance on scarce and expensive precious metals while also enabling more sustainable production of everyday materials. By precisely controlling the atomic structure of tungsten carbide, researchers have unlocked its potential as a game-changing alternative to traditional catalysts.
