Oxides of vanadium, titanium and graphitic carbon nitride (g-CN) are well known for their catalytic activities. In order to achieve synergic catalytic effects, a novel nanocomposite (NC) i.e. VO/TiO/g-CN has been synthesized by a very simple, ecofriendly and nonhazardous hydrothermal method. The fabricated NC was characterized employing UV-Visible, FTIR, SEM, and XRD techniques. UV-Visible and FTIR analysis indicated the formation of the nanocomposite and XRD analysis confirmed the association of VO and TiO with g-CN in nanocomposite. SEM study indicated the hetero-structure of NC having size ranging from 50 to 80 nm and it was found having hexagonal crystallite structure. The synthesized nanocomposite exhibited excellent scavenging of free radicals DPPH (91%) and ABTS (64%) that are responsible for the oxidation of biomolecules. Therefore, NC can be claimed having biomolecule oxidation protective potential. In addition, photocatalytic ability for the degradation of methylene blue (MB) and methyl orange (MO) was also achieved up to 94% and 89% respectively. The synthesized novel nanocomposite exhibited excellent potential to remove free radicals and dyes from aqueous medium which can be further used for the environmental remediation.
钒、钛和石墨相氮化碳（g-CN）的氧化物以其催化活性而闻名。为了实现协同催化效应，通过一种非常简单、环保和无危险的水热方法合成了一种新型纳米复合材料（NC），即 VO/TiO/g-CN。所制备的 NC 采用 UV-可见、FTIR、SEM 和 XRD 技术进行了表征。UV-可见和 FTIR 分析表明形成了纳米复合材料，XRD 分析证实了 VO 和 TiO 在纳米复合材料中与 g-CN 的结合。SEM 研究表明 NC 具有 50 至 80nm 大小的异质结构，并且发现其具有六方晶系结构。合成的纳米复合材料对负责生物分子氧化的自由基 DPPH（91%）和 ABTS（64%）具有出色的清除能力。因此，可以说 NC 具有生物分子氧化保护潜力。此外，NC 还具有降解亚甲基蓝（MB）和甲基橙（MO）的光催化能力，分别达到 94%和 89%。合成的新型纳米复合材料具有从水介质中去除自由基和染料的优异潜力，可进一步用于环境修复。
