A novel two-stage synthesis for 3C–SiC nanowires by carbothermic reduction and their photoluminescence properties

Ti-Modified LaFeO3/β-SiC Alveolar Foams as Immobilized Dual Catalysts with Combined Photo-Fenton and Photocatalytic Activity

“…Figure shows the XRD patterns of the bare β-SiC foam support and of the different β-SiC foam-supported LFO-based catalysts. In addition to the diffraction lines corresponding to the (111), (200), (202), (311), and (222) planes of the fcc structure β-SiC polymorph (JCPDS card 03-065-0360), all the patterns can be indexed to the Pbnm orthorhombic unit cell of LaFeO 3 (JCPDS card 070-7777), independently of the presence of titanium and of the titanium source, similarly to what was observed for the pristine and Ti-modified LaFeO 3 powders . No single oxide phase is observed, and the mean crystallite size of the supported LFO-based phase is not influenced by the introduction of titanium during the sol–gel Pechini synthesis, with values within the 21–25 nm range.…”

“…13.2−14.6 m 2 /g) and pore volume was observed for the Ti-LFO/β-SiC foams. 48 all the patterns can be indexed to the Pbnm orthorhombic unit cell of LaFeO 3 (JCPDS card 070-7777), independently of the presence of titanium and of the titanium source, similarly to what was observed for the pristine and Ti-modified LaFeO 3 powders. 10 No single oxide phase is observed, and the mean S3).…”

Coating-free TiO2@β-SiC alveolar foams as a ready-to-use composite photocatalyst with tunable adsorption properties for water treatment

“…2A and B . They all exhibited diffraction lines corresponding to the (111), (200), (202), (311) and (222) planes of the β-SiC polymorph in the fcc structure, 23 which were similar to those of both the reference β-SiC foam and the β-SiC foam after the first carburization steps (labelled as C-rich β-SiC foam considering the presence of residual unreacted carbon species, see later Fig. 5A ).…”

Synthesis of SiC/SiO2 core–shell nanowires with good optical properties on Ni/SiO2/Si substrate via ferrocene pyrolysis at low temperature

“…The PL characteristics are observed to be quite variable, which strongly depends on the morphology (SiO 2 ), size (diameter), structure (defects) 7 – 25 . Shena et al 20 synthesized the SiC/SiO 2 nanowires with emission peak at 408 nm, the SiC/SiO 2 nanowires synthesized by Zhang et al 17 shows emission peak at 438 nm and Shen et al synthesized the SiC/SiO 2 nanowires with emission peak at 401 nm 19 .…”

“…In this study, the high-density SiC/SiO 2 core-shell nanowires were synthesized on the nickel coated SiO 2 (100 nm)/Si substrate by chemical vapor deposition (CVD) method at 1000 °C with ferrocene precursor. The CVD technology was used to control the shape and composition of the as-synthesized nanowires to improve PL properties which are not worse than the previous papers [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] .…”
