In Situ UV-Vis-NIR Analysis of Adsorption Sites and Particle Size in Supported Catalysts: the MaPPS and CT-RICh Toolkit (Materials Today Nano)

Raw data for in situ UV-Vis-NIR measurements on a Au(5.7 nm)/TiO2 catalysts exposed to alternating O2, He, H2, and He gases to accompany Fig. 2 in manuscript: "In Situ UV-Vis-NIR Analysis of Adsorption Sites and Particle Size in Supported Catalysts: the MaPPS and CT-RICh Toolkit" accepted for publication in: Materials Today Nano. The first data set are csv files containing matrices of absorbance data as a function of wavelength and exposure time. Each gas exposure is labeled with a single number starting at 01463 (three files, one with the matrix data, two other files with corresponding values for X and Y scales in the matrix). Subsequent gas exposures are labeled in ascending order, with the last one file ending in 01473. This data can be analyzed to extract the maximum Au plasmon peak position after the Au/TiO2 was exposed to any of the gases. The second data set are the obtained surface plasmon resonance peaks for each gas exposure after fitting to a 5th order polynomial equation around +/- 60 nm of the maximum plasmon peak.
