Through electrostatic interaction and high-temperature reduction methods, rGO was closely coated onto the surface of TiO2 nanotubes. Even at a high temperature of 700 °C, the nanotube morphology of TiO2 (anatase) was preserved because of the assistance of rGO, which provides a framework that prevents the tubes from breaking into particles and undergoing a phase transformation. The rGO/TiO2 nano...

Here we report the fabrication of highly transparent graphene oxide (GO) reinforced TiO2 nanocomposite thin film and demonstrate that it enhances power conversion efficiency dye-sensitized solar cells (DSSC) when used as photoanode. TiO2-GO films with varying GO concentrations are deposited on top fluorine doped tin (FTO) coated glass substrate by easy, cost-effective sol-gel spin coating techn...

In this study TiO2/polysiloxane(SiBi) thin films modified with different concentrations of graphene oxide (GO) were prepared by ink-jet printing on flexible polyethylene terephthalate (PET) substrates. Prepared coatings characterized means scanning electron microscopy (SEM), transmission (TEM), X-ray photoelectron spectroscopy (XPS), ultraviolet (UPS), Raman and water contact angle measurements...

We have prepared a model catalytic system by depositing Pd onto a TiO2(110) surface held at approximately 720 K. Scanning tunneling microscopy (STM) reveals well-defined Pd nanocrystals consisting of (111) top facets with {111} and {100} side facets. The Pd nanocrystals go down to about 10 nm in width and 1.3 nm in height. Top facets can be imaged with atomic resolution, indicating the absence ...

Two novel ternary hybrid nanoparticles (THNp) consisting of graphene oxide (GO) and reduced oxides (rGO) were added to samples DNA. The effect the addition on thermal denaturation DNA was studied by measuring absorbance using a temperature-controlled Perkin Elmer UV spectrophotometer. Adding GO-TiO2-Ag rGO-TiO2-Ag lowered temperature template significantly. affect rate. optimal concentrations f...

Trong bài báo này, graphen oxit (GO) được tổng hợp từ bột graphit bằng phương pháp Hummer; GO khử axit ascorbic thành dạng (rGO). Titan dioxit (TiO2) cấu trúc nano có tính ổn định vật lý và hóa học cao với nhiều ứng dụng, đặc biệt là trong lĩnh vực môi trường. Vật liệu TiO2/rGO trưng nhiễu xạ tia X (XRD) hiển vi điện tử quét (SEM) để chứng minh các điểm hình thái của bề mặt chất hấp phụ. Quá tr...
