摘要

介绍了在超临界异丙醇条件下，还原氧化石墨烯上顺序合成锐钛矿改性氧化钛纳米颗粒。在这种情况下，只有氧化石墨烯被还原为还原氧化石墨烯。以超临界异丙醇为氧化石墨烯还原剂和反应介质，建立了在还原氧化石墨烯上制备氧化钛纳米颗粒的一步法(一锅法)。利用x射线相分析、透射电子显微镜和原子力谱等方法对所得纳米复合材料进行了研究。

Preparation of titanium oxide nanoparticles on the surface of reduced graphene oxide in supercritical isopropanol

Sequential synthesis of anatase modification titanium oxide nanoparticles on reduced graphene oxide in supercritical isopropanol is described. In this case, only graphene oxide was reduced to reduced graphene oxide. A one-stage method (one-pot) was also developed for the preparation of titanium oxide nanoparticles on reduced graphene oxide, where supercritical isopropanol was the graphene oxide reducing agent and the reaction medium. The resulting nanocomposites were studied using X-ray phase analysis, transmission electron microscopy, and atomic force spectroscopy methods.

期刊介绍： Journal “Radioelectronics. Nanosystems. Information Technologies” (abbr RENSIT) publishes original articles, reviews and brief reports, not previously published, on topical problems in radioelectronics (including biomedical) and fundamentals of information, nano- and biotechnologies and adjacent areas of physics and mathematics. The authors of the journal are academicians, corresponding members and foreign members of the Russian Academy of Natural Sciences (RANS) and their colleagues, as well as other russian and foreign authors on the proposal of the members of RANS, which can be obtained by the author before sending articles to the editor or after its arrival on the recommendation of a member of the editorial board or another member of the RANS, who gave the opinion on the article at the request of the editior. The editors will accept articles in both Russian and English languages. Articles are internally peer reviewed (double-blind peer review) by members of the Editorial Board. Some articles undergo external review, if necessary. Designed for researchers, graduate students, physics students of senior courses and teachers. It turns out 2 times a year (that includes 2 rooms)
