Abstract
Bulk ZrO(x)H(y) is an effective catalyst for amine regeneration in CO(2) absorption, but its high cost and poor support stability may hinder application. Here, ZrO(x)H(y) is deposited as a theoratical monolayer within MCM-41 mesopores, achieving similar stable catalytic activity to bulk ZrO(x)H(y) with just 13 wt% Zr loading, offering a cost-effective path toward industrial use.
