To identify the environmental and compositional factors governing framework symmetry changes between monoclinic and orthorhombic phases in ZSM-5 zeolite.
Conducted X-ray diffraction experiments on ZSM-5 zeolite samples to measure crystal framework symmetry.
Assessed symmetry phase transitions across different temperatures, aluminium concentrations, and sorbate molecule conditions.
Observed that framework symmetry transitions between monoclinic and orthorhombic states in ZSM-5 zeolite depend directly on sample temperature.
Identified that aluminium concentration and the presence of sorbate molecules also govern these structural phase shifts.
