Nanoporous Fe-Based Alloy Prepared by Selective Dissolution:
An Effective Fenton Catalyst for Water Remediation
Posted on 2017-02-23 - 09:13
A fully nanoporous
Fe-rich alloy, prepared by selective dissolution
of melt-spun Fe43.5Cu56.5 ribbons, exhibits
outstanding properties as a heterogeneous Fenton catalyst toward the
degradation of methyl orange (MO) in aqueous solution. In addition,
the ferromagnetic characteristics of this material enable its wireless
manipulation toward specific locations within polluted wastewater.
The influence of selective dissolution on the microstructure, sample
morphology (surface and cross-section), elemental composition, and
magnetic properties of the resulting nanoporous alloy is investigated.
The dealloying procedure enhances the saturation magnetization and
drastically increases the catalytic performance (i.e., the time required
for full degradation of MO from the medium is reduced by a factor
of approximately 2 by subjecting the Fe43.5Cu56.5 ribbons to prior dealloying). Remarkably, the effectiveness of this
nanoporous material surpasses the results obtained by the homogeneous
Fenton reaction using an equivalent concentration of Fe cations leached
into the media from the nanoporous alloy. The different factors that
promote the high catalytic activity are discussed. The outstanding
catalytic activity, together with the simplicity of the synthetic
procedure, makes this material very appealing for water remediation
using advanced Fenton processes.
