Cationic manganese (MnP - [Mn(T4MPyP)]⁵⁺) and anionic iron (FeP - [Fe(TDFSPP)]^3–) metalloporphyrins in conjunction with zinc oxide of different morphologies, were synthesized. After characterization by different instrumental techniques, the metalloporphyrins were immobilized on the obtained zinc oxide and the catalysts were evaluated regarding the oxidation of cyclohexane, using iodosylbenzene (PhIO) as model oxidant. In the absence of light, the activities of FeP/ZnO were higher than those obtained by neat ZnO and MnP/ZnO. Furthermore, under the reaction conditions of 1:100:1000 catalyst/oxidant/substrate, with acetonitrile as solvent, for 1 h at 25 °C without any radiation source, the reactions were selective for ketone. The same occurred for the neat FeP under homogeneous conditions. In contrast, when the reaction proportions were changed to 1:20:1000 catalyst/oxidant/substrate and when the catalyst amount was increased 10 times, the selectivity was for alcohol. Under irradiation with a dichroic halogen lamp (50 W), all the systems containing FeP showed higher selectivity for alcohol, while when MnP was used, increments like those with FeP were not observed, probably due to the structural differences between FeP and MnP. This FeP to MnP replacement led to spectral differences that might have been responsible for the inability of MnP to interact efficiently with the radiation emitted by the dichroic halogen lamp as well as promoting the higher amount of ketone produced in comparison with the FeP/ZnO system.

阳离子锰 (MnP - [Mn(T4MPyP)] ⁵⁺ ) 和阴离子铁 (FeP - [Fe(TDFSPP)] ^3–) 金属卟啉与不同形态的氧化锌一起被合成。在通过不同的仪器技术表征后，将金属卟啉固定在获得的氧化锌上，并使用碘代苯 (PhIO) 作为模型氧化剂评估催化剂对环己烷的氧化。在没有光照的情况下，FeP/ZnO 的活性高于纯 ZnO 和 MnP/ZnO 获得的活性。此外，在1：100：1000催化剂/氧化剂/底物的反应条件下，以乙腈为溶剂，25℃，无任何辐射源1小时，反应对酮具有选择性。在均匀条件下，纯 FeP 也会发生同样的情况。相反，当反应比例更改为 1:20 时：1000催化剂/氧化剂/底物，当催化剂用量增加10倍时，选择性为醇。在二色性卤素灯 (50 W) 照射下，所有包含 FeP 的系统都显示出更高的酒精选择性，而当使用 MnP 时，没有观察到像 FeP 那样的增量，这可能是由于 FeP 和 MnP 之间的结构差异。这种 FeP 到 MnP 的替代导致光谱差异，这可能是导致 MnP 无法与二向色卤素灯发出的辐射有效相互作用以及与 FeP/ZnO 系统相比促进产生更多酮的原因。而当使用 MnP 时，没有观察到像 FeP 那样的增量，这可能是由于 FeP 和 MnP 之间的结构差异。这种 FeP 到 MnP 的替代导致光谱差异，这可能是导致 MnP 无法与二向色卤素灯发出的辐射有效相互作用以及与 FeP/ZnO 系统相比促进产生更多酮的原因。而当使用 MnP 时，没有观察到像 FeP 那样的增量，这可能是由于 FeP 和 MnP 之间的结构差异。这种 FeP 到 MnP 的替代导致光谱差异，这可能是导致 MnP 无法与二向色卤素灯发出的辐射有效相互作用以及与 FeP/ZnO 系统相比促进产生更多酮的原因。
