This thesis dives into the application of supported fibrous catalysts for air pollution control since atmospheric contamination is responsible for severely damaging the environment and harming all living beings on this planet.
Fiber-based catalysts are an attractive option in catalysis since fibers can enhance heat and mass transfer, reduce the pressure drop, and provide versatility in terms of materials, sizes and shapes. In order to obtain fibrous supports, a biotemplating synthesis route was adopted to produce different types of ceramic supports.
Two different deposition methods were used to incorporate active oxide phases for oxidation reactions: the traditional wet impregnation technique and a novel approach by performing a glidarc plasma precipitation-deposition.
The abatement of three different air contaminants was studied through catalytic oxidation reactions: a solid reactant, representative of particulate matter, along with two different gaseous reactants, one of them coming from the incomplete combustion of hydrocarbons, and the second one, from the volatile organic compound family.
A wide array of characterization techniques was applied to understanding the main physicochemical, morphological and textural properties of the catalysts. Great effort was put into trying to correlate catalytic activity with characterization results.
This work contributes to gaining insight into the synthesis of fibrous catalysts, on how their properties are affected by following different deposition paths, and their influence on the catalytic activity towards the oxidation of three different air pollutants.
