Novel nickel oxide surface structure improves efficiency of methane conversion

The short version

• Researchers discovered that a dynamic atomic unit forming on nickel oxide converts methane more efficiently than metallic nickel.[ScienceDaily]
• A catalyst using 0.8 weight percent nickel achieved a 92% methane conversion rate, rivaling formulations using ten times as much metal.[ScienceDaily]
• Theoretical models indicate the structure lowers the activation barrier for breaking methane chemical bonds to 12.5 kcal/mol.[ScienceDaily]
• The findings could lead to lower metal requirements in industrial catalysts, though large-scale application remains to be shown.[ScienceDaily]

Key facts

• An atomic structure dynamic to nickel oxide surfaces during methane conversion was found to be more effective than metallic nickel.[ScienceDaily]
• A catalyst with 0.8 weight percent nickel matched the performance of one containing 10 times more metal.[ScienceDaily]
• The low-nickel catalyst converted 92% of methane during testing.[ScienceDaily]
• Calculations showed the surface configuration lowered the activation barrier for methane C-H bond breaking to 12.5 kcal/mol.[ScienceDaily]
