(385b) Photocatalytic Core-Shell Nanotube Array Converting Carbon Dioxide and Water to Fuels
AIChE Annual Meeting
Tuesday, November 16, 2021 - 12:55pm to 1:15pm
In-situ monitoring by electrochemical, optical, infrared, and mass spectroscopy plays a central role to demonstrate and optimize the photocatalytic performance of the nanotube array. To be more specific, electrochemical and optical spectroscopy establishes charge-carriers transfer mechanism through the nanotube wall, in-situ infrared spectroscopy illuminates how Ag nanoclusters photo-deposited outside the tubes serve as catalytic sites for visible light-driven CO2 reduction to CO, and mass spectroscopy allows to quantify O2 evolution from visible light-driven water oxidation inside the tubes.
