Composite materials are made from two or more constituent materials with distinct physical or chemical properties that, when combined, produce a material with characteristics which are at least to some degree different from its individual components. Nanocomposite materials are composed of different materials of which at least one has nanoscale dimensions. Common types of nanocomposites consist of a combination of two different elements, with a nanoparticle that is linked to, or surrounded by, another organic or inorganic material, for example in a core‐shell or heterostructure configuration. A general family of nanoparticle composites concerns the coating of a nanoscale material by a polymer, SiO2 or carbon. Other materials, such as graphene or graphene oxide (GO), are used as supports forming composites when nanoscale materials are deposited onto them. In this Review we focus on magnetic nanocomposites, describing their synthetic methods, physical properties and applications. Several types of nanocomposites are presented, according to their composition, morphology or surface functionalization. Their applications are largely due to the synergistic effects that appear thanks to the co‐existence of two different materials and to their interface, resulting in properties often better than those of their single‐phase components. Applications discussed concern magnetically separable catalysts, water treatment, diagnostics‐sensing and biomedicine.

“…Electronic features of dispersed Fe have been studied by Bao et al [76], who showed that the amount and location of iron oxide nanoparticles in MICNCs are critical parameters in determining the shape, size, and crystal structure of nanoparticles, which correlate with their magnetization. It was concluded that the zero valence and large surface area of iron oxide nanoparticles create a high level of photocatalytic activity.…”

Physical and chemical methods have been developed for water and wastewater treatments. Adsorption is an attractive method due to its simplicity and low cost, and it has been widely employed in industrial treatment. In advanced schemes, chemical oxidation and photocatalytic oxidation have been recognized as effective methods for wastewater-containing organic compounds. The use of magnetic iron oxide in these methods has received much attention. Magnetic iron oxide nanocomposite adsorbents have been recognized as favorable materials due to their stability, high adsorption capacities, and recoverability, compared to conventional sorbents. Magnetic iron oxide nanocomposites have also been reported to be effective in photocatalytic and chemical oxidation processes. The current review has presented recent developments in techniques using magnetic iron oxide nanocomposites for water treatment applications. The review highlights the synthesis method and compares modifications for adsorbent, photocatalytic oxidation, and chemical oxidation processes. Future prospects for the use of nanocomposites have been presented.

“…[ 4–6 ] However, how to fully take advantage of the solar energy by enhancing light absorption response as much as possible and achieve efficient solar energy conversion are significant factors for the improvement of photocatalytic performance, which is still a challenge. [ 3 ] Even though various semiconductor photocatalysts including TiO 2, [ 7 ] ZnO, [ 8 ] Fe 3 O 4 , [ 9 ] and Bi 2 MoO 6 photocatalysts [ 10 ] have been synthesized, their low visible‐light response and inefficient separation of photogenerated carriers restrict their practical applications. [ 11 ] Thereby, it is desirable to explore novel catalytic materials with high considerable utilization of solar energy and high photogenerated electron–hole pair separation efficiency to solve environmental and energy crisis.…”

Efficient photocatalytic CO2 reduction into clean chemical fuels using visible light remains an enormous challenge. Construction of hierarchical heterostructured photocatalysts has gained tremendous popularity due to their distinctive structural characteristics and synergetic effect that they can boost the visible‐light photoactivities. Based on this, a three‐step solvothermal method is proposed to construct hierarchical BiOI/MoS2/CdS heterostructured microspheres. The addition of MoS2 and CdS not only plays a significant role in the improvement of visible‐light absorption, but also works as a carrier electron mediator, inhibiting the recombination of electrons–holes effectively. High CH4 yield (46.22 μmol h−1 g−1) and CO yield (36.98 μmol h−1 g−1) are achieved for BiOI/MoS2/CdS‐0.03 heterostructured microspheres under simulated sunlight irradiation because of the wide solar light‐driven response, abundant active sites and high charge separation ability. Therefore, this study provides an efficient strategy for constructing heterostructured catalysts with remarkable visible‐light response photocatalytic CO2 reduction activity.
