In this study, ternary mixed metal oxide (Ce2O3/La2O3/Fe3O4) catalysts were synthesized for reduction of SO2 to sulfur by CH4. The response surface method (RSM) was used to optimize the synthesis conditions. The XRD, FESEM, BET, BJH, EDX and NH3-TPD analyses were performed to characterize the synthesized catalysts. The optimum conditions were obtained for an activated […]
Activated carbon from pine cone (PCAC) was used as a precursor to prepare Fe3O4/magnetic activated carbon (MPCAC). Here, the removal of linear alkylbenzene sulfonate (LAS) was studied using catalytic ozonation process (COP) in exposure to MPCAC. Subsequently, it was compared with PCAC. Moreover, the effects of solution’s initial pH, catalyst dosage, and the time of […]
The Cu(II) complex of 2,6-pyridine dicarboxylic acid (PydcH2, dipiconilic acid) was successfully prepared and readily trapped in the nanocavity of zeolite-X (NaX) through a flexible synthetic method. The characterization of nanocomposite ([Cu(pydcH2)(pydc)]-NaX) was performed by FT-IR, XRD, BET isotherm, SEM, TEM, and elemental analysis, that approved the encapsulating of coordination compound in the channels of […]
