In this work, reduced graphene oxide (rGO) nanocomposites doped with nitrogen (N), sulfur (S) and transitional metal (Ni, Co, Fe) were synthesized by using a simple one-step in-situ hydrothermal approach. Electrochemical characterization showed that rGO-NS-Ni was the most prominent catalyst for glucose oxidation. The current density of the direct glucose alkaline fuel cell (DGAFC) with rGO-NS-Ni as the anode catalyst reached 148.0 mA/cm2, which was 40.82% higher than the blank group. The DGAFC exhibited a maximum power density of 48 W/m2, which was more than 2.08 folds than that of blank group. The catalyst was further characterized by SEM, XPS and Raman. It was speculated that the boosted performance was due to the synergistic effect of N, S-doped rGO and the metallic redox couples, (Ni2+/Ni3+, Co2+/Co3+ and Fe2+/Fe3+), which created more active sites and accelerated electron transfer. This research can provide insights for the development of environmental benign catalysts and promote the application of the DGAFCs.

We investigated the fabrication of Ca/Al layered double hydroxide (LDHs) via a one-step hydrothermal approach with slow hydrolysis of urea at a low temperature without further annealing required. The as-synthesized Ca/Al LDHs nanostructures obtained were defined using Fourier transforms infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), powder X-ray diffraction (XRD), and scanning electron microscopy (SEM). The results demonstrated that Ca/Al LDHs exhibit excellent adsorption performance on Congo red anionic dyes in aqueous solution. The adsorption capacity of the Ca/Al LDHs toward Congo red was found to be 59.41 mg/g.

Xrd And Tem

α-FeOOH nanorods were fabricated via a one-step hydrothermal approach using iron nitrate hydrate (Fe(NO3)3·9H2O) as iron source, cetyltrimethylammonium bromide (CTAB) as a template and acetic acid (CH3COOH) solution as solvent. XRD, SEM, TEM, and TGA were applied to characterize the samples. The as-prepared α-FeOOH nanorods are around 50 nm in diameters and 1 µm in length. The aspect ratio is 20. The XRD and TEM results indicated that both CTAB and CH3COOH were crucial for the formation of α-FeOOH nanorods. The heat treatment at the temperature of 250°C led to the transformation of α-FeOOH to α-Fe2O3, and the crystal phase transformation was completed at 340°C. The lower transformation temperature compared to bulk α-FeOOH could be attributed to the decreased size of the as-prepared sample.
