The catalytic system, distinguished by its innovative hybrid structure that includes Fe<sup>2+<\/sup>&nbsp;and imidazole on an oxidized carbon matrix in the presence of a polydentate phosphine, demonstrated remarkable turnover numbers (TONs), reaching 428,880 and effectively decomposed 53 mL of formic acid (FA) over 8 cycles. This sustained performance underscores the effectiveness, stability, and durability of the catalyst, which was further evidenced by a cumulative H<sub>2<\/sub>&nbsp;production of 22.1 L over the same period. Structural analysis using Raman, Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and electron paramagnetic resonance (EPR) spectroscopy revealed structural changes in the used catalyst compared to the pristine material. Despite the observed structural changes, such as Fe-site aggregation and matrix restructuring, the catalyst maintained a high efficiency, with enhanced activity noted with each reuse. The stability of the carbon-based radicals from the matrix was confirmed, which is crucial for the sustained performance of the catalyst. Notably, upon repeated use, the catalyst underwent a self-reconstruction process, which is linked to alterations in the hydrophobicity of the catalyst and the overall structure, resulting in enhanced water durability and improved performance, making AC<sub>ox<\/sub>@ImFe a robust and effective system for sustainable H<sub>2<\/sub>&nbsp;production.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Christos Gkatziouras, Maria Solakidou, Maria Louloudi.
