1 digital object.

Description

This collection contains data used in publication and is linked with figure numbers. Figure 1(a) data were collected using UV-vis spectroscopy and BET surface area analysis. Figure 1(b) contains measurements conducted using a pH meter. Figures 2(b), 3, 4, 5, 6, 7(a), and 7(b) contains data collected using ATR-FTIR spectroscopy. Figure 7(c) contains normalized integrated peak areas calculated from the ATR-FTIR data provided in Figure 7(a) and 7(b). Each spreadsheet is labeled with Figure number. Where there are multiple panes, you will find multiple sheets per spreadsheet. The sheets are labeled as pane (a), pane (b) etc.
