Abstract The high density nucleation of α-Al2O3 nanocrystallites was observed by rapid heating of the aluminum formate hydroxide-based precursor powder at 1200 °C for 50 s. The nucleation of α-Al2O3 nanocrystallites with less 10 nm in size from hi

This study is one of the few to develop a strategy that inhibits coke deposition by loading Cr on zeolite defects. We revealed that Cr6+ species, which interacted with hydroxyl groups in the zeolite framework inhibited coke deposition.

An efficient and simple methodology was proposed to synthesize CHA zeolite without the use of solvent and OSDA. The synthesis strategy is based on a mechanochemical-assisted interzeolite transformation using only Na-type FAU zeolite and KOH as starti
