英文摘要 | Heterogeneous crystallization of manganese (oxyhydr)oxides (MnO x ) on iron (oxyhydr)oxides (FeO x ) is crucial for the biogeochemical cycling of Mn, yet atomic-level insights into this process are important but relatively limited. Herein, we revealed the distinct adsorption, oxidation, and crystallization mechanisms of Mn on hematite (Hem), ferrihydrite (Fhy), and goethite (Gth). Gth exhibited highest ability in Mn(II) removal and oxidation, followed by Hem and Fhy. Manganite and hausmannite were the main MnO x products with distinct proportions, and morphologies cross the systems. MnO x growth mechanisms involve surface-induced nucleation, crystallization by particle attachment (CPA), and self-catalyzed growth. On Fhy, self-catalyzed growth was dominant; for Gth, surface-induced nucleation was prevalent, supplemented by CPA; and Hem combined all three mechanisms. These distinct mechanisms led to nanoparticles primarily of hausmannite on Gth and nanowires of manganite and hausmannite on Hem and Fhy, with those on Hem displaying lower aspect ratios. Differences in MnO x structure and morphology were attributed to Mn(II)-FeO x complexation, FeO x electronic band structure, and crystal structure mismatch between MnO x and FeO x , which respectively influenced the direct and indirect electron transfer and heterogeneous nucleation efficiency. This work advances our understanding of MnO x crystallization on FeO x at the nanoscale, explaining the diverse morphology and structure of MnO x in different environments. |
