Zeolites on 3D-printed open metal framework structure: metal migration into zeolite promoted catalytic cracking of endothermic fuels for flight vehicles.

Selective laser melting printed metal lattice structures functionalised using zeolites have been shown as a promising new generation of catalysts. The unprecedented catalytic activity can be explained by metal migration (most likely chromium) from the support into the zeolite phase making it a promising candidate for endothermic fuels for high-speed flight vehicles.
