Graphite-like carbon nitride (g-C3N4) was synthesized in large quantities at 300ºC under nitrogen by a solidstate reaction route. Furthermore, Al3+ and Mg2+ intercalation of g-C3N4 was performed by an electrochemical method. The starting C3N4 materials and intercalation compounds were characterized by X-ray powder diffraction, Fourier transform infrared spectra, thermogravimetry, transmission electron microscopy, and X-ray photoelectron spectroscopy. The possible structure model of intercalation compounds was proposed. The cation-¼ interactions and electrostatic interactions were used to explain the changes of microstructure and chemical bonds before and after intercalation.

Porous indium oxide nanorods have been synthesized by calcination of indium hydroxide, which were prepared through a simple sol-gel and aging process at low temperature in the presence of sodium dodecyl sulfate (SDS). X-ray diffraction (XRD), scanning electron microscopy (SEM), and high-resolution transmission electron microscopy (HRTEM) were adopted to characterize the phase composition and morphology of the resulted samples. The sensing properties towards H2 were examined at 340°C, which showed better sensitivity and quick response/recovery merits.

Poly-crystalline In(OH)3 nanorods have been successfully prepared via a urea-based precipitation using the colloidal carbon spheres as the templates. After calcinations, the resulted In2O3 nanorods with poly-crystalline structure were fabricated. Structure and morphology of the product were characterized by X-ray diffraction (XRD), and transmission electron microscopy (TEM). The possible formation process was schemed. The sensor gas properties towards C2H5OH and CO were examined.
