The focus of the second funding period will be the identification of active sites and reaction mechanisms. Cobalt-based spinels and perovskites synthesized in area C will be routinely screened for their catalytic properties in different liquid-phase oxidation reactions. The kinetic studies conducted in conventional batch reactors will be complemented by steady-state experiments in a continuous-flow microreactor. Additionally, reusability and leaching will be investigated by recovering the catalysts for post-catalytic characterization and recycling tests. The kinetic studies will be supported by spectroscopy (ATR-IR, EPR (B06)) and also include the decomposition of hydroperoxides. Furthermore, the role of the solvent in the catalytic cycle will be assessed.

第二个供资期的重点将是确定活性位点和反应机制。将对C区合成的钴基尖晶石和钙钛矿进行常规筛选，以确定其在不同液相氧化反应中的催化性能。在传统的间歇式反应器中进行的动力学研究将补充在连续流微反应器中的稳态实验。此外，将通过回收催化剂进行催化后表征和回收测试来研究可重复使用性和沥滤性。动力学研究将得到光谱学（ATR-IR、EPR（B 06））的支持，还包括氢过氧化物的分解。此外，将评估溶剂在催化循环中的作用。
