Application of Inkjet Printing to Fabricate Controllable Pt Catalyst Patterns for Low Temperature Catalytic Combustion

摘要

Different platinum catalysts patterns such as dots array and films were successfully fabricated by directly inkjet printing of catalyst precursor inks on the substrate. It offers a feasible way for platinum catalyst deposition by precise control of catalyst loading, deposition position, and morphology. The effects on drying behavior of printed catalyst droplet on the catalytic performance of low temperature methanol catalytic combustion were investigated. The results show that the conversion of methanol over printed Platinum patterns in the catalytic combustion is approximately 85% at 100°C.
