Density functional calculations on the distribution of Ti in a Y zeolite and its influence on acidity
The question of whether Ti replaces Al or Si in the framework of a Y zeolite is studied using a density function theory (DFT) calculation.The distribution properties of Ti in a zeolite are discussed by comparing substitution energies, they show that of the seventeen Si positions investigated the preferred substitution is the one where the Si atoms are located next to the Al, and that the Al is more easily replaced than Si.
