Article
Catalytic decomposition of methane (CDM) into hydrogen and solid carbon materials (CH4 → 2H2 + C) is a promising approach to achieve environmentally friendly H2 production. However, large amounts of carbon (i.e., H2 to carbon mass ratio of 1 to 3) is generated as a solid by-product. Herein, we show that graphitic carbon materials generated in CDM o...
Article
Direct catalytic decomposition of methane (CDM) has been studied as a possible emission-free hydrogen production route for over 100 years. However, the high cost of catalyst regeneration limits its practical applications. Here, we demonstrate that the solid by-product from CDM using Fe ore catalysts compromising carbon nano onions encapsulated with...
Article
This study reports a wet spinning method to spin composite micro-fibres of 2D liquid crystalline graphene oxide (GO) and exfoliated MoS2 nanosheets with very high MoS2 loading. The MoS2 dispersion was found to be isotropic irrespective of solvent type or solute concentration in the dispersion and thus found to be non-spinnable via wet spinning proc...
Article
In this study, N-doped reduced graphene oxide (rGO) wrapped carbon micro fibres (CFs) were synthesized by one-step high temperature pyrolysis method. Free-standing binder-free electrodes of N-doped rGO on CF were fabricated to apply in extended flexible fibrous supercapacitors and sodium-ion batteries (NIBs). The results showed that the attachment...
Article
A facile synthesis of three-dimensional (3D) network of copper confined nitrogen‐doped graphene (NG)/carbon nanotube (CNT) with high atomic percentage of nitrogen (10.1 at.%) has been reported. The homogenous intercalation of the CNT network in-between the graphene layers decorated with copper nanoparticles take place which inhibits the self-agglom...
Article
Surface modification of carbon microfibres (CF) represents a promising and challenging alternative for creating multiscale and multifunctional hierarchical lightweight high-performance composite materials. In this study, a low-temperature chemical method is developed to graft layered graphene oxide (GO) directly onto CF through covalent bonding, an...
Article
A multifunctional nano-heterostructured electrocatalyst of transitional metal/metal oxide (nickel/nickel oxide) embedded on nitrogen-doped graphene is reported. The hybrid composite of N-doped graphene nanosheets with high atomic percentage of nitrogen (8.2 at%) and embedded with highly distributed nickel/nickel oxide nanoparticles inside the graph...
Article
A free-standing, 3D, macro/microstructured atomic-cobalt/cobalt-oxide–reduced-graphene-oxide (Co/Co3O4-Gr) composite has been developed for complete water splitting. The self-assembled porous morphology associated with the metal/metal oxide active sites makes the whole surface of the electrode conducive toward catalyzing hydrogen and oxygen evoluti...
Article
A non-enzymatic sensing platform was developed for detecting glucose and hydrogen peroxide using nitrogen doped graphene decorated with copper-nickel nanoparticles. The synthesized CuNi-NGr composite presented excellent electrocatalytic interaction with glucose and hydrogen peroxide owing to the synergistic effect of copper, nickel and N-graphene....
Article
A novel chemical synthesis method has been developed to directly graft graphene quantum dots (GQDs) onto carbon fibre (CF) in-situ via covalent ester linkages at low temperature (90 °C). SEM and TEM images depict the grafting of GQDs on CF showing about 75% of the GQD falls below 40 nm. The grafting was further confirmed by FTIR, RAMAN, XPS and XRD...
Article
An amperometric non-enzymatic glucose sensor was developed based on nitrogen-doped graphene with dispersed copper nanoparticles (Cu-NGr). The sensing element was tested in conjunction with a modified glassy carbon electrode for glucose detection. The Cu-NGr composite was prepared by one pot synthesis from a mixture of graphene oxide, copper nitrate...
Chapter
This chapter discusses about the surface preparation methods of fibres prior to use in composite materials to improve their performance or to introduce other essential characteristics. Chemical coatings, plasma and chemical surface modification techniques as well as mechanical treatments are presented. Also, advanced surface tailoring using nano-co...

A novel method for nitrogen doping of graphene via solid-state impregnation was developed using graphene oxide (GO) as the raw substrate and aminoterephthalic acid as the doping agent via a facile thermal treatment at 750 °C. The structure, morphology and chemical composition of the synthesised N-doped graphene were characterised using XRD, SEM, ED...

Nitrogen-doped graphene was successfully synthesised from graphene oxide (GO) and 2-methylimidazole composite via thermal treatment under argon flow at 700 o C within 1h. This synthesised N-doped graphene exhibits homogeneous nitrogen doping with concentration of ~5% in three different nitrogen configuration namelypyridinic N, pyrrolic N and graphi...

Fermentation of potato and carambola juice was investigated using Molds and Agaricus as a potential source of amylase. The amylatic activity of Moulds and Agaricus were studied and the effects of different parameters, such as starch concentrations, pH, incubation time, temperature were investigated. The maximum enzyme activity obtained for Moulds w...
Article
This study describes an atomic layer deposition (ALD) approach for the fabrication of Pt nanocatalysts supported on graphene oxide (GO) sheets and their electrocatalytic performance in electro-oxidation of formic acid. The ALD process for forming the Pt atomic layer involves two self-limiting reactions and, thus, induces the decoration of ALD-Pt on...
Article
This study describes a pulse electrodeposition approach for the synthesis of palladium (Pd) nanocatalysts supported on graphene oxide (GO) sheets and their electrocatalytic performance in a single stack of proton exchange membrane fuel cell (PEMFC). Star-like Pd clusters consisting of several nanotips are well deposited over the GO sheets, and the...
Article
This work investigates the electrochemical activity and durability of bimetallic Pt–Co electrocatalysts on carbon nanotube (CNT) electrodes, which are prepared by using a microwave-assisted polyol process within a short period of ∼6min. Multilayered CNTs are directly grown on carbon paper (CP) substrate by catalytic chemical vapor deposition with N...
