Abstract :
Surface modified Mg-Fe layered double
hydroxide materials by CTAB are used for photo
catalytic degradation of methyl orange. Mg-Fe LDH
(material-1) was prepared by co-precipitation method
and material-2 was prepared by intercalation of CTAB
into material-1. Further, calcination and surface
modification of material-2 was done to get material-3.All
these materials were characterized by FT-IR. Structure
and composition was confirmed by XRD and SEM with
EDX. Surface area of prepared material 1,2 and 3 was
determined by BET analysis and the values of surface
area are 28.54, 18.29 and 4.95m2
/g and pore size is 10.6,
7.9 and 9.2 nm respectively. The band gap values
obtained on the basis of DRS studies for materials-1,2
and 3 are 3.9 , 3.9 & 3.2 eV respectively.
Photo catalytic degradation of methyl orange using
material 1, 2 & 3 in the presence of 10 W LED bulb was
studied under identical conditions and progress of the
reaction was monitored by UV-Vis spectrometer. The
catalytic efficiency of material 3, 2 and 1 is 90%, 32%,
2% respectively. Decreasing in particle size after
surface modification and enhanced mesoporous nature
accounts for the highest catalytic efficiency of material -3
and it is cost effective easy to prepared and eco-friendly.
