Degradation Of Methyl Orange

Abstract In this paper, NiAlCe hydrotalcite was prepared by co-precipitation method and hydrothermal method in different volume fractions of ethylene glycol-water mixed solvent and polyethylene glycol-water mixed solvent, and the effect of photocatalytic degradation of methyl orange under ultraviolet light was studied. Samples were characterized by XRD, XPS, UV-Vis and FT-IR in order to find the reasons for the improvement of photocatalytic performance under co-solvent system. NiAlCe-10%EG(h) and NiAlCe-15%PEG(h) had smaller particle size, which was beneficial to photocatalytic performance. The degradation rate of methyl orange could reach up to 100% in 42 min using NiAlCe hydrotalcite with 10% volume fraction of EG and in 48 min using NiAlCe hydrotalcite with 15% volume fraction of PEG. The photocatalytic effect of NiAlCe hydrotalcite samples prepared by hydrothermal method were better than that prepared by co-precipitation method. This provided a new type of catalyst for the degradation of dyes: preparing with ethylene glycol-water mixed solvent.
