Which outcome reduces the catalytic activity titanium hydride?

A)Surface area decreases through sintering
B)Volumetric expansion increases reaction sites
C)Hydrogen coverage diminishes oxidation
D)Metallic lattice induces phase transition

💡 Explanation

When titanium hydride SINTERS the reducing the surface area, surface area reduction constricts active sites needed for catalysis becomes reduced because there are less place for adsorbed gasses and intermediates; therefore, sintering deactivates, rather than enhances activity or changes the bulk phase
