“…Metal organic frameworks (MOFs) are recently used in different areas such as gas storage, [14] adsorption, [15] photocatalysis, [16] evolution of hydrogen, [17] and molecular sensing [18] . Among these MOFs, zirconium MOFs are widely used lately due to their structures′ high stability in an aqueous medium even after functionalized with other materials [19–21] .…”

In this study, NiFe2O4@AC/UiO‐66(Zr) composites were successfully prepared with different ratios of UiO‐66(Zr) as support for NiFe2O4@AC, (1 : 1), (2 : 1) and (3 : 1) named NiFe2O4@AC/UiO‐66(Zr)‐1, NiFe2O4@AC/UiO‐66(Zr)‐2 and NiFe2O4@AC/UiO‐66(Zr)‐3, respectively. The prepared composites were characterized by X‐Ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), X‐Ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET), ultraviolet‐visible diffuse reflectance (UV‐Vis/DRS) spectroscopy, PL (Photoluminescence) study. The synthesized composites′ efficiencies to enhance the photodegradation of alizarin yellow R (AYR) under visible‐light were evaluated. The results identified that NiFe2O4@AC/UiO‐66(Zr)‐2 is the most photoreactive photocatalyst with the lowest bandgap ∼1.7 eV. NiFe2O4@AC/UiO‐66(Zr)‐2 shows higher photodegradation efficiency (97.9 %) compared to NiFe2O4@AC/UiO‐66(Zr)‐1 and NiFe2O4@AC/UiO‐66(Zr)‐3 with photodegradation efficiency of 75.1 % and 89.9 %, respectively after 180 min under visible‐light. The photodegradation reaction of AYR was found to be pseudo first‐order reaction, and the rate constant (Ka) for NiFe2O4@AC/UiO‐66(Zr)‐1, NiFe2O4@AC/UiO‐66(Zr)‐2, and NiFe2O4@AC/UiO‐66(Zr)‐3 are 0.0072 min−1, 0.0204 min−1, and 0.0122 min−1, consecutively. The effects of various conditions such as initial concentration and photocatalyst dose on the photodegradation of AYR were determined. The high photodegradation efficiency of NiFe2O4@AC/UiO‐66(Zr)‐2 composite is because of the heterojunction and effective charge transfer between NiFe2O4@AC and UiO‐66(Zr). NiFe2O4@AC/UiO‐66(Zr)‐2 photocatalyst exhibits photocatalytic stability and reusability up to five cycles.

“…Molecular Imprinted Polymers (MIP) are based on imprinted cavities designed for the target template elements. The holes created in the polymeric matrix match the template molecule in shape and size; for these reasons, MIP are interesting elements for direct recognition in electrochemical sensors providing excellent properties of sensitivity and selectivity [10]. The selection of the polymer matrix is crucial in the preparation of MIP electrochemical sensors 3 [11], and a large variety of polymers has been employed for sensing and molecular imprinted applications [12].…”

“…Their use in combination with MIPs for optical sensing has not been fully explored yet, only a few works can be found in the literature but due to the synergetic properties of the hybrid materials based on both components, it is expected that scientific production will considerably grow during the following years. The reader is referred to the literature for further information concerning MOF@MIP-based sensors [179].…”

We report on the development of new optical sensors using molecularly imprinted polymers (MIPs) combined with different materials and explore the novel strategies followed in order to overcome some of the limitations found during the last decade in terms of performance. This review pretends to offer a general overview, mainly focused on the last 3 years, on how the new fabrication procedures enable the synthesis of hybrid materials enhancing not only the recognition ability of the polymer but the optical signal. Introduction describes MIPs as biomimetic recognition elements, their properties and applications, emphasizing on each step of the fabrication/recognition procedure. The state of the art is presented and the change in the publication trend between electrochemical and optical sensor devices is thoroughly discussed according to the new fabrication and micro/nano-structuring techniques paving the way for a new generation of MIP-based optical sensors. We want to offer the reader a different perspective based on the materials science in contrast to other overviews. Different substrates for anchoring MIPs are considered and distributed in different sections according to the dimensionality and the nature of the composite, highlighting the synergetic effect obtained as a result of merging both materials to achieve the final goal.
