Synchrotron infrared spectroscopic high-throughput screening of multi-composite photocatalyst films for air purification

Compared with conventional one-sample-at-a-time synthesis and characterization, combinatorial and high-throughput methods are effective strategies for rapidly searching for photocatalysts.

Summary:Compared with conventional one-sample-at-a-time synthesis and characterization, combinatorial and high-throughput methods are effective strategies for rapidly searching for photocatalysts. Herein, we developed a synchrotron-based infrared microscope with an updated homemade in situ gas reaction cell to speed up the screening of photocatalysts for air purification with the case of 0.9%Fe 3+ /0.07%Nb 5+ -TiO 2 for formaldehyde removal. Synchrotron-based infrared microscope was used for the high-throughput screening of Fe 3+ /Nb 5+ doped TiO 2 photocatalysts for air purification.
