“…To gain more insight into the composition of the deposited composites, Raman analysis was conducted. Figure 4 d shows the Raman spectra of rGO and Co 3 O 4 /rGO, which displayed the main features of graphene-based materials with D (defects and disorders in the graphitic lattice) and G band (crystalline part of graphene) [ 36 ]. The Raman spectrum of rGO exhibited a D band at ~1366 cm −1 and a G band at ~1603 cm −1 .…”

In this work, the facile fabrication of Co3O4 particles/reduced graphene oxide (Co3O4/rGO) composites on Indium tin oxide (ITO) slide was achieved by an electrophoretic deposition and annealing process. The deposition time and ratio of the precursors were optimized. Structural characterization and chemical composition investigation indicated successful loading of Co3O4 particles on graphene sheets. When applied as a non-enzymatic H2O2 sensor, Co3O4/rGO showed significant electrocatalytic activity, with a wide linear range (0.1–19.5 mM) and high sensitivity (0.2247 mA mM−1 cm−2). The good anti-interference ability, reproducibility, and long-term stability of the constructed sensor were also presented. The application of Co3O4/rGO in real sample analysis was evaluated in human urine sample with satisfactory results, indicating the feasibility of the sensor in physiological and medical applications.

“…The platinum electrode, carbon paper TGPH-060 (Toray, Tokyo, Japan), and graphene oxide suspension were then used for the cathode, anode, and electrolyte, respectively. The CP was deposited electrophoretically at 15 V for 10 min, cleaned ultrasonically, and dried at 100 °C for two hours to obtain the rGO/CP [ 25 , 26 ], as shown in Figure 1 .…”

The diffusion layer (DL) in the structure of the membrane electrode assembly (MEA) of a micro direct methanol fuel cell (μDMFC) plays an essential role in reactant/product mass transfer and catalyst loading. The material selection and structure design of the μDMFC affects its performance. In this work, a reduced graphene oxide/carbon paper (rGO/CP) was proposed and prepared for the anode DL of a μDMFC. It was prepared using electrophoretic sedimentation combined with an in situ reduction method. The rGO/CP reduced the cell’s ohmic and charge transfer resistances. Meanwhile, it provided more significant mass transfer resistance to reduce the methanol crossover, allowing the cell to operate stably at higher concentrations for a longer duration than conventional μDMFCs. The experimental results showed that the maximum power density increased by 53% compared with the traditional anode DL of carbon paper.

Carbon dioxide generated by the combustion of fossil fuels exacerbates global environmental problems and hydrogen produced by renewable energy is a viable alternative in the continuous transition to sustainable and eco‐conscience development. Electrocatalysts are vital to electrocatalytic reactions and plasma surface modification is one of the promising techniques to modify nanoscale electrocatalysts for water splitting. Up to now, a comprehensive review on the latest developments, challenges, and opportunities of plasma‐tailored defective electrocatalysts for water electrolysis and hydrogen fuel cells is lacking. This paper systematically summarizes the current status of hydrogen production and fuel cell technologies, plasma principles and advantages, plasma‐tailored defective electrocatalysts from the perspective of water splitting and fuel cell applications, advanced characterization of defects, relationship between materials structure and catalytic activity of electrocatalysts, and finally challenges, opportunities, and future roadmap of plasma technologies. This review serves as a reference for future development of hydrogen technologies and offers insights into the structural tailoring of catalytic materials.
