In this study, the metal complex (5, 10, 15, 20‐tetrakis‐(4‐sulfonatophenyl)‐porphyrin
manganese (III) chloride; denoted as MnTSPP) represents a promising efficient and …

phenanthroline‐based molten salt as a bifunctional sulfonic acid [Phen (SO3H) 2] Cl2 was
designed and synthesized. The described nano molten salt has two SO3H acid groups and …

We report a simple, clean, and straightforward method for the non-covalent immobilization of
protic acidic ionic liquids on nano silica sulfuric acid. Initially, two organic zwitterions were …

In this research work, a novel strategy for the heterogenization of sultone based acidic ionic
liquids via their non-covalent immobilization on nano silica sulfuric acid is reported and the …
