ArticleRedox approaches derived Tin (IV) oxide nanoparticles/graphene nanocomposites as the near-infrared absorber for selective human prostate cancer cells destruction Abstract In this paper, Tin (IV) oxide nanoparticles/graphene (SnO 2 /GR) nanocomposites were prepared via vacuum thermo treatment of Tin (0) and graphene oxide (GO). A redox reaction would occur readily in this process, in which the novel oxygen donor: GO could act as the oxidizing agent to oxidize Tin (0) to Tin (IV), meanwhile, the graphene precursor: GO would be simultaneously reduced to graphene by Tin (0) readily. The resulted composites were characterized by Fourier transform infrared spectrometry, scanning electron microscopy, and X-ray diffraction spectroscopy ect.. The novel SnO 2 /GR nanocomposites could combine both advantages of inorganic metal nanoparticles and graphene for near infrared spectroscopy (NIR) light absorption to generate heat, which fosters SnO 2 /GR a special candidate for photothermal ablation therapy (PTA) with NIR. Further investigations show that the SnO 2 /GR nanocomposites with NIR features could provide viable option for enhancing the thermal deposition and specificity of hyperthermia treatments for elimination of human prostate cancer (PC3).Citation: J S.

“…Using thermoregulated ILs, a good recyclability of the nanocatalysts by simple phase separation can be achieved, while the catalytic process is driven under monophasic conditions [53,54]. Herein, catalytic active carbonyl species are formed under reaction conditions [53,171,176]. The chemoselectivity and activity are strongly influenced by nanoparticles size.…”

This feature article introduces the strategies on the design of highly efficient nanoparticle (NP) catalytic systems in ionic liquids (ILs). The employment of functional ILs as the media for NP preparation and catalysis could prove advantageous in terms of enhancing both NP stability and catalytic activity. Hydroxyl group functionalized ILs, in particular, exhibited a remarkable promotion effect on a variety of reactions catalyzed by NPs, such as hydrogenation over Rh NPs, hydrodehalogenation over Pt NPs and Suzuki reaction over Pd NPs. In some cases, tailor-made stabilizer is used in addition to keep the NPs sufficiently stable. For example, a carboxylic group modified polyvinylpyrrolidone endows NPs three-fold stabilization, including steric, electrostatic and ligand stabilizations, which leads to excellent stability of the NPs. The catalytic activities of these NPs, on the other hand, are not compromised, as each of these stabilizations is not too strong. Following that, the article describes our recent work on the rational design of bimetallic NPs in ILs and the development of multifunctional systems involving NPs for a tandem reaction sequence that convert lignin-derived phenolic compounds into fuels.
