Improving degradation of real wastewaters with self-heating magnetic nanocatalysts

Cascade strategy for triggered radical release by magnetic nanoparticles grafted with thermosensitive alkoxyamine

“…Nanoparticle-assisted magnetothermia is one of the promising modern nanoscience ways, permitting remote and locally providing important heat activation and control by an external stimulus, an alternating current (ac) magnetic field. This concept is widely exploited in nanomedicine in the hyperthermia treatment of different diseases, [1][2][3][4] in environmental applications, 5,6 recently in catalysis, [7][8][9][10][11] in enzymatic reaction, [12][13][14] and other fields. Among different nanoobjects used as magnetic nanoheaters, iron oxide nanoparticles (IONPs) are the most known in the literature since their composition, size, morphology, and surface state, and therefore, magnetic properties can be precisely controlled.…”

Preparation and characterization of α-Fe2O3/Fe3O4 heteroplasmon nanoparticles via the hydrolysis-combustion-calcination process of iron nitrate

“…Magnetic nanoparticles are a kind of nanomaterials. It is widely used in the fields of biology, medicine, and chemical engineering [9][10][11][12][13], on account of its unique nano-size effect and magnetic properties. For example, Chen et al [14] proposed Ti 2 O 3 nanoparticles as a pure Ti 3+ system for the electrosynthesis of NH 3 and the yield of NH 3 was significantly better than other titanium-based adsorbents.…”

Next generation of nanozymes: A perspective of the challenges to match biological performance

“…23 Nanozymes combining the catalytic ability with the physical properties of solid-state matter for smart response to remote stimuli (e.g., magnetic, optical, or electronic) could constitute a breakthrough for technologies such as pollutant elimination, groundwater remediation systems, nanomedicine, and biomedical devices. 24,25 Currently, the list of nanomaterials being explored as sources of catalytic mechanisms is large and diversified. The biocatalytic performance of nanozymes is currently being tested for antitumor therapeutics 26 and for other different oxidative stress related diseases, as in the case of the catalase-like activity reported in cerium oxide nanozymes against the excess of reactive oxygen species (ROS) for lowering the oxidative stress.…”
