Abstract

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%Fe³⁺/0.07%Nb⁵⁺-TiO₂ for formaldehyde removal.
