Scientists Take Major Step Toward Circular Carbon Economy; Develop Long-lasting Catalyst

Scientists have taken a significant step toward a circular carbon economy by creating a long-lasting, economic catalyst that recycles greenhouse gases into components that can be utilized in fuel, hydrogen gas, and other chemical substances. The outcomes might be revolutionary in the effort to reverse global warming.

The catalyst, made from cheap and abundant nickel, magnesium, and molybdenum, initiates and accelerates the speed of reaction that converts carbon dioxide and methane into hydrogen gas.

This conversion is called “dry reforming,” where dangerous gases, akin to carbon dioxide, are processed to generate more useful chemical substances that could be refined to be used in fuel, plastics, and even pharmaceuticals. It’s an active procedure; however, it previously required rare and costly metals similar to platinum and rhodium to induce a brief and inefficient chemical reaction.

Other researchers had beforehand proposed nickel as a new economical solution; however, carbon byproducts would build-up, and the surface nanoparticles would bind together on the more affordable metal, radically altering the composition and geometry of the catalyst and rendering it useless.

The researchers generated nickel-molybdenum nanoparticles under a reductive setting in the presence of single-crystalline magnesium oxide. As the substances had been heated under reactive fuel, the nanoparticles moved on the pristine crystal surface seeking anchoring points.

The resulting activated catalyst sealed its high-energy sites. It permanently mounted the location of the nanoparticles—meaning that the nickel-based catalyst won’t have a carbon build-up, nor will the surface particles bind to each other.
