“…A CHNO explosive detonation synthesizing carbon nanotubes at low pressure and temperature by introducing a cobalt/nickel catalyst and/or paraffin into the detonation system [13], [14] . The chemical reaction of explosive detonation is very fast and complex, producing free atoms of C, H, N and O with dangling bonds [15], [16] . Since their discovery and large-scale synthesis, CNTs has attracted enormous interest due to their various unique physical and chemical properties [17] , [18] , [19] which exhibit excellent structural flexibility and fluidity.…”

AbstractsThe CNTs and CNTs doping with Fe based composites were rapid fabricated by Gaseous detonation decomposition of oxygen, benzene and ferrocene mixed precursors. A series of novel experiments were designed to investigate the condensation and formation of carbon structural nanomaterials. The TEM, EDS, EDX, XRD and Raman characterizations provide fundamental evidence of the high yield and purity of the CNTs, CNTs doping with Fe composites during the gaseous detonation reaction process. The results showed that CNTs, CNTs with Fe based nanocrystals, spherical CCFNPs and their mixed products are with variant morphologies. The obtained CNTs is multi-walled carbon nanotubes and CNTs doping with a body-centered cubic iron or iron carbide cores, which can be obtained respectively through adjusting and controlling the detonation reaction environment and the precursors.

“…The post-reduction catalyst clearly shows the diffraction peaks corresponding to Ni 0 and SrO. The peaks found at 2θ values of 44 [31,32]. Generally, the high-temperature reduction of perovskites leads to the formation of nanoparticles of B site metal (e.g., Ni) dispersed on the oxide formed by the A site metal (e.g., Sr) [33,34].…”

The SrNiO3 perovskite catalyst was synthesized by the citrate sol-gel method and supported on γ-Al2O3 and Nickel foam, which was used to produce syngas (CO and H2) via dry reforming of propane (DRP). Several techniques characterized the physicochemical properties of the fresh and spent perovskite catalyst. The X-ray diffractograms (XRD) characterization confirmed the formation of the perovskite compound. Before the catalytic activity test, SrNiO3 perovskite catalyst was reduced in the H2 atmosphere. Results indicated that the H2 reduction slightly increased the activity of the SrNiO3 perovskite catalyst. The catalytic activity was examined for the CO2/C3H8 ratio of 3 and reaction temperatures in the range of 550 °C–700 °C. The results from the catalytic study achieved 88% conversion of C3H8 and 66% conversion of CO2 with SrNiO3/NiF at 700 °C. Also, syngas with a maximum concentration of 21 vol.% of CO and 29 vol.% of H2 was produced from the DRP. The strong basicity of SrNiO3 perovskite enhanced the CO selectivity, resulting in minimal carbon formation. Post reaction catalyst characterization showed the presence of carbon deposition which could have originated from propane decomposition.
