The samples had been prepared at pH 8.78 and 9.37, where the particle size was 58 ± 11 nm and 49 ± 9 nm, respectively. Solid-state NMR measurements showed that the former contained a minute amount of bicarbonate species, whereas we did not detect any for the latter. While the AMC sample prepared at higher pH exhibited a one-step decomposition at 413°C, the one at lower pH decomposed in two steps at 425 and 510°C. The solubility products of AMC prepared at two pH are statistically identical and the average value is estimated to be 6.3 × 10?6. ? 2021 The Chemical Society Located in Taipei & Wiley-VCH GmbH |
