Perforation routes towards practical nano-porous graphene and analogous materials engineering

Carbon, 2019
Abstract Nano-perforated graphene sheets have emerged as exciting two-dimensional materials for a broad range of scientific and commercial purposes, due to their modified physicochemical properties as compared to native graphene materials. Nanoporous graphene sheets as a class of two-dimensional materials with thicknesses ranging from sub-nanometre ...

Ti-doped nano-porous graphene: A material for hydrogen storage and sensor

Frontiers of Physics, 2011
Clustering of Ti on carbon nanostructures has proved to be an obstacle in their use as hydrogen storagematerials. Using density functional theory we show that Ti atoms will not cluster at moderate concentrations when doped into nanoporous graphene. Since each Ti atom can bind up to three hydrogen molecules with an average binding energy of 0.54 eV/H2 ...

Three‐dimensional graphene on a nano‐porous 4H‐silicon carbide backbone: a novel material for food sensing applications

Journal of the Science of Food and Agriculture, 2023
BackgroundSensors that are sensitive to volatile organic compounds, and thus able to monitor the conservation state of food, are precious because they work non‐destructively and allow avoiding direct contact with the food, ensuring hygienic conditions. In particular, the monitoring of rancidity would solve a widespread issue in food storage.ResultsThe ...

A three-dimensional TiO2/graphene porous composite with nano-carbon deposition for supercapacitor

Journal of Materials Science, 2015
Titanium dioxide/graphene composite is receiving intensive attention because of its potential applications in energy field. Herein, we report the preparation of a three-dimensional TiO2/graphene porous composite prepared by using a sacrificial template strategy, avoiding the usual hydrothermal and freeze-drying processes. Graphene oxide sheets and TiO2

Synthesis of self‐assembled and porous nano titania‐graphene oxide hybrids for toughening the epoxy

Polymer Composites, 2020
AbstractNano titania (nTiO2) aggregated graphene oxide (GO) hybrid nanostructures were successfully prepared by employing 3‐(Aminopropyl) triethoxysilane (APTES)‐modified nTiO2 as precursor material. The resulting self‐assembled core‐shell hybrid structure was observed to have hierarchical porous structure with nTiO2 forming the core and GO forming the

Experimental and theoretical demonstrations of ultraviolet absorption enhancement in porous nano-membrane graphene

Carbon, 2019
Abstract Ultraviolet absorbing materials have important applications in which graphene is a strong candidate, yet, few efforts are being exerted to improve its absorption in the UV-region. We show that UV absorption in single-layer graphene can be enhanced by manoeuvring its electronic properties through converting it to a nanomembrane-like structure,

Deposition mechanism of polydisperse xanthan gum-stabilized graphene oxide/nano-iron composites in saturated porous medium

Journal of Cleaner Production, 2020
Abstract Engineered materials (EMs) have shown promise for remediation of groundwater contaminants and the potential application relies on the delivery of aqueous solutions of EMs to a targeted subsurface location or region. Thus, the ability to accurately predict nanoparticle transport and retention in saturated porous media is one of the most ...

Confining nano FeSb2S4 in carbon nanotube/oxide graphene 3D porous networks for high-capacity sodium ion battery anode

Journal of Alloys and Compounds, 2021
Abstract Sodium ion batteries (SIBs) are promising alternative for lithium ion batteries (LIBs) due to the abundant reserve of Na compared to Li. Although the three-dimensional (3D) thick electrodes for LIBs have been widely studied, corresponding researches are seldom reported for SIBs anode. Herein, a high theoretical capacity binary metal sulfide (

Graphene/metal-organic framework nano-sandwiches derived N, P-codoped porous carbon nanosheets as robust material for electrochemical analysis

Analytica Chimica Acta, 2023
Construction of novel two-dimensional porous carbon nanosheets with superior electrochemical activity is of great challenge. Here, graphene/ZIF-8 nano-sandwiches derived N, P-codoped porous carbon nanosheets (N, P-codoped PCN) was easily obtained by sequential room temperature self-assembly and high-temperature carbonization method.
