2022年6月1日 · We developed TiO 2 –rGO nanocomposites with high exfoliated rGO content upto 47.1% (TG4) by weight hitherto not reported, through green redox synthesis. Progressive reduction of TiO 2 nanocrystal size and their in situ intercalation occurred on increasing rGO via one pot synthesis, not reported previously and forming highly stable Ti–O–C bonds.

Using hybrid density functional theory calculations, we demonstrate that the presence of oxygen functional groups and the formation of interfacial cross-links (Ti–O–C covalent bonds and strong hydrogen bonds between TiO 2 and RGO) have a major effect on the electronic properties of RGO and RGO-based composites.

2023年12月1日 · In this study, plant-based titanium dioxide-reduced graphene oxide (TiO2-rGO) photocatalyst was synthesized by a hydrothermal method using Azadirachta indica (AI) leaf extract. Morphological and chemical properties of the AI-TiO 2 …

2025年1月9日 · The optimized rGO-TiO2 composites exhibit an enhanced photocatalytic degradation of rhodamine B (RhB) under simulated sunlight conditions, about 99.95% for 4% rGO-TiO2 within 80 min. The first-order reaction rate constant (k) of 4% rGO-TiO2 (0.0867 min−1) is 5.42 times higher than that of nano TiO2 (0.0135 min−1).

2024年10月1日 · We introduce a polydopamine-assisted synthesis of an rGO/TiO 2 nanocomposite. This composite consists of oxygen vacancy-rich TiO 2 nanoparticles uniformly anchored on few-layered rGO nanosheets through interfacial C-Ti and N -Ti bonds, referred to as rGO@TiO 2-x. The obtained material serves as a Schottky-type heterojunction host.

2023年10月27日 · Hydrothermally reduced chemical method synthesis of rGO-TiO2 nanocomposites (NCs) with varied concentrations of graphene oxide (GO) from 1 to 5 wt% was investigated for its morphological, structural, chemical bonding, structural defects, optical and electrochemical properties.

To take advantage of sunlight for its photodegradation, TiO 2 –reduced graphene oxide (TiO 2 –rGO) nanocomposites with different GO contents (0.25–3.0 wt%) were synthesized and characterized by scanning electron microscopy (SEM), UV-vis and ATR-FTIR spectroscopies.

2018年10月31日 · Herein, reduced graphene oxide (rGO)-supported (TiO 2) composites with different morphologies (octahedral, truncated octahedral and elliptical) are successfully synthesized through a hydrothermal strategy.

2022年9月27日 · Aimed at improving the electromagnetic (EM) matching characteristics of graphene and improving its EM wave absorption performance, we successfully prepared titanium dioxide/reduced graphene oxide (TiO 2 /rGO) aerogels via one-step hydrothermal method and annealing treatment.
