Preparation of graphene/Au aerogel film through the hydrothermal process and application for H₂O₂ detection

Abstract

Graphene/gold nanoparticle aerogel film was prepared through the hydrothermal method, and could be used as an electrochemical sensor for detecting H2O2.

Dual-Purpose CuFe2O4-rGO-Based Nanocomposite for Asymmetric Flexible Supercapacitors and Catalytic Reduction of Nitroaromatic Derivatives

“…The multifunctional materials can be strategically designed by combining different materials with suitable properties to form a hybrid material to satisfy previously unfeasible performance metrics. In such a scenario, nanocomposites composed of graphene decorated with ferrite nanoparticles are eminently fascinating nanocomposites. − In the present study, we have demonstrated the multifunctional nature of a CuFe 2 O 4 -rGO nanocomposite by using it in the construction of an all-solid-state flexible asymmetric supercapacitor device and a catalyst for the reduction of various nitroaromatic compounds.…”

2D nanomaterial aerogels integrated with phase change materials: a comprehensive review

“…Furthermore, combining chemical reduction and hydrothermal processes can accelerate the removal of oxygen-containing functional groups and the chemical-induced assembly of reduced graphene oxide (rGO) nanosheets. In 2019, Shen et al 144 developed graphene aerogels using a hydrothermal-assisted method. For this aim, a proper content of l -ascorbic acid was added to the GO suspension as a reduction agent, and then the resulting suspension underwent hydrothermal reduction at 180 °C for 14 h. Eventually, the aerogel composites were fabricated by freeze-drying (−50 °C) the frozen rGO hydrogels.…”
