One Step

Graphene-based materials are widely studied to enable significant improvements in electroanalytical devices requiring new generations of robust, sensitive and low-cost electrodes. In this paper, we present a direct one-step route to synthetize a functional nitrogen-doped graphene film onto a Ni-covered silicon electrode substrate heated at high temperature, by pulsed laser deposition of carbon in the presence of a surrounding nitrogen atmosphere, with no post-deposition transfer of the film. With the ferrocene methanol system, the functionalized electrode exhibits excellent reversibility, close to the theoretical value of 59 mV, and very high sensitivity to hydrogen peroxide oxidation. Our electroanalytical results were correlated with the composition and nanoarchitecture of the N-doped graphene film containing 1.75 at % of nitrogen and identified as a few-layer defected and textured graphene film containing a balanced mixture of graphitic-N and pyrrolic-N chemical functions. The absence of nitrogen dopant in the graphene film considerably degraded some electroanalytical performances. Heat treatment extended beyond the high temperature graphene synthesis did not significantly improve any of the performances. This work contributes to a better understanding of the electrochemical mechanisms of doped graphene-based electrodes obtained by a direct and controlled synthesis process.

Fully inkjet-printed device fabrication is a crucial goal to enable large-area printed electronics. The limited number of two-dimensional (2D) material inks, the bottom-gated structures, and the low current on/off ratio of thin-film transistors (TFTs) has impeded the practical applications of the printed 2D material TFTs. In the search for TFTs with high current ratios, we introduce a stable and efficient method of nitrogen-doped graphene (NDG) ink preparation for inkjet printing by liquid-phase exfoliation. The NDG thin film is print-stacked with molybdenum disulfide (MoS2) by multiple printing passes to construct a MoS2–NDG stack. We demonstrate top-gated fully inkjet-printed MoS2–NDG transistors with silver drain, source, and gate electrodes, and a barium titanate (BaTiO3) dielectric. A 100% inkjet-printed MoS2–NDG vertical 2D active heterostructure layer transistor with a current on/off ratio of 1200 is exhibited. The results may lead towards the development of all-printed 2D material-based transistor switches.

Nitrogen doped graphene (NG) was synthesized by chemical vapor deposition at 950 °C, using metal tetrapyrazinoporphyrazine (MPTpz, M= Fe, Co, the mass ratio of FePTPz/ CoPTpz is 1: 1) as a precursor. IR testing of FePTpz indicates the existence of C−N and C=N, which was prepared through microwave method. The NG shows a uniformly distributed and cotton-like structure. TEM images suggests that the single and multilayer NG coexists in the products and it is of a graphite-like structure. Electrocatalytic activity of the NG towards oxygen reduction reaction (ORR) was investigated by the cyclic voltammetry at different scan rates from 20 mV·s-1 to 100 mV·s-1 in an acidic solution. Peak currents and background currents of the NG rose as the scan rate increasing. The maximum peak current is 290.24 mA·cm−2, exhibiting well electrocatalytic activity of the NG toward ORR.
