Synthesis – properties correlation and the unexpected role of the titania support on the Grignard surface modification

摘要: Abstract While the impact of reaction conditions on surface modification with Grignard reactants has been studied for silica supports, such information is absent metal oxides like titania. Differences between modified titania and are observed, making it paramount to explore mechanism. A detailed study reported, a focus chain length alkyl reactant, its concentration, time temperature, type support. increase in reduces amount organic groups surface, temperature show little/no influence degree. However, support used percentage amorphous phase present significant grafted groups. Even though concentration no clear degree, they can cause changes hydroxyl population, which thus not linked Furthermore, reduced during functionalization. This reduction dependents reactant. Similarly, this
