Abstract
In this work, a grass-like film of magnesium oxide was formed on the carbon fiber paper through a hydrothermal route which was subsequently applied for the removal of methyl orange at neutral pH. The developed composite was characterized by utilizing the various physicochemical characterization techniques, confirming the formation of needle-like MgO, which was uniformly decorated on the surface of carbon fiber paper. The MgO@C composite film exhibited an excellent removal performance and removed 91% of the methyl orange under ambient reaction conditions. Furthermore, it is also found that the MgO@C composite exhibited an excellent removal efficiency of 86.37% for three cycles, which shows its capability of recycling and reuse for the practical purposes. Thus, the study provides a new insight into development of high-efficiency porous composite film with potential for large-scale practical applications.
