Generating abundant Co3+ species via H2O/N2 mixed atmosphere pyrolysis of CoZn-ZIF for catalytic transfer hydrogenation

Key Points

• The aim is to generate Co3+ species from CoZn-ZIF catalysts using a specific pyrolysis atmosphere.
• Utilized a mixed H2O/N2 atmosphere for pyrolysis instead of pure N2.
• Examined the impact on Co3+ species generation and their acidity.
• Conducted catalytic transfer hydrogenation using the resulting catalysts.
• Significantly increased generation of Co3+ species was observed.
• Enhanced Lewis acidity attributed to the H2O/N2 pyrolysis environment.
• Improvement in γ-valerolactone yield was noted, indicating better catalytic performance.
