Influence of support ionicity on the hydrogen chemisorption of Pt particles dispersed in Y zeolite: consequences for Pt particle size determination using the H/M method

Zeolite Y-supported Pt particles were studied by high-resolution transmission electron microscopy (HRTEM), extended X-ray absorption fine structure (EXAFS), and H 2 chemisorption experiments. The ionicity (i.e., electron richness of the zeolite oxygen atoms) was altered by using different cations (N...
