In a new approach, chromium (III) tetraaza dioxo ligand was grafted onto functionalized SBA- 15 after four step reactions by using coordinating ability of anchored amino functionalized SBA-15. After the termination of each step, the obtained product was characterized by FT-IR, low-angle X-ray diffraction (LA-XRD), N2 adsorption–desorption isotherms (Brunauer– Emmett–Teller (BET)–Barret–Joyner–Halenda (BJH)) and thermogravimetric analysis ( ...
