Tuesday publication update! 📖 Hydrogen spillover is a cornerstone phenomenon in heterogeneous catalysis, but its full impact on catalyst supports has remained unclear. Using Atmosphere AX in situ STEM, authors from the Tongji University directly observed how active hydrogen species reshape catalyst supports during the reversed water–gas shift (RWGS) reaction.
What did they find?
💠 Active hydrogen accelerated lattice oxygen evolution in MoO₃
🔬 Ru–MoO₃ nanosheets transformed into a porous, jigsaw-like structure
📈 Enhanced formation of active CO₂ sites drove 14.3% CO₂ conversion with nearly 100% CO selectivity at 300 °C—approaching thermodynamic limits
By directly visualizing the dynamic support reconstruction process, the authors uncovered how hydrogen spillover shapes both morphology and catalytic performance.
