Characterization and catalytic performance of porous carbon prepared using in situ-formed aluminophosphate framework as template

Preparation and Characterization of Flame-Retardant Aluminum Hypophosphite/Poly(Vinyl Alcohol) Composite

“…34 The pattern exhibits a broad diffraction peak centered at about 23°and a small peak at about 44°, which can be ascribed to (002), (100) diffraction of graphite. 35 The d 002 interlayer spacing obtained from the (002) peak is 0.386 nm, which is larger than that of graphite (d 002 = 0.335 nm). It indicates that the graphitic levels of the carbonaceous chars are not very high and oxygencontaining functional groups bond at the basal plane of graphitized carbon, 33,36 with good agreements with the Raman results.…”

“…The char was washed by HF and HNO 3 to remove the inorganic salts and amorphous carbon . The pattern exhibits a broad diffraction peak centered at about 23° and a small peak at about 44°, which can be ascribed to (002), (100) diffraction of graphite . The d 002 interlayer spacing obtained from the (002) peak is 0.386 nm, which is larger than that of graphite ( d 002 = 0.335 nm).…”

“…The graphitic carbon is constituted by stacking the polycyclic aromatic species . The aluminum phosphates act as a template for the formation of graphitic carbon , The salts of aluminum phosphate facilitate the transformation of the poorly graphitizable carbon to a relatively more crystalline char. Furthermore, the thermally stable aluminum phosphate acts as adhesive to cross-link the polyaromatic structure to make char intact and robust. , And aluminum phosphate showing a ceramic-like structure can thermally stabilize and mechanically reinforce the char. − …”

In situ synthesis of a MoS2/CoOOH hybrid by a facile wet chemical method and the catalytic oxidation of CO in epoxy resin during decomposition

“…The XRD pattern exhibits a broad diffraction peak centered at about 23 and can be assigned to (002) diffraction of graphite. 41 The visible peaks at 36.6 , 42.5 and 61.6 are ascribed to the diffraction of CoO, and the others correspond well to the metallic Co and MoO 3 , respectively. [42][43][44] For the FT-IR spectrum, the peak at 3412 cm À1 is assigned to water.…”

Silicoaluminophosphate (SAPO)-Templated Activated Carbons

“…Their frameworks are mainly covalently bonded and have no net charge. However, the chemistry of AlPO 4 s and microporous silicates (SiO 2 ) is different and AlPO 4 s can be dissolved in aqueous solutions of HCl. − Even though this chemical difference is promising for the use of AlPO 4 s to derive ACs, only a limited amount of work has been performed. One previous study has shown that carbon nanotubes can be synthesized within the channels of an AlPO 4 -5 material .…”
