Abstract P, Se-codoped g-C3N4 (PSeCN) nanosheet was in situ prepared by facile thermal polymerization of melamine, phosphonitrilic chloride trimer, and selenium black powder as the precursors. It was found as a suitable support for the immobilization of silver nanoparticles (Ag NPs). The prepared nanocatalyst was fully characterized via standard analysis methods including EDX, ICP-OES, XRD, FT-IR, SEM, TEM, and BET. This PSeCN/Ag nanocatalyst with a higher specific surface area compared with CN,...

Design and preparation of low-cost, effective, and novel catalysts are important topics in the field of heterogeneous catalysis from academic and industrial perspectives. Recently, heteroatom-doped porous carbon/metal materials have received significant attention as promising catalysts in divergent organic reactions. Incorporation of heteroatom into the carbon framework can tailor the properties of carbon, providing suitable interaction between support and metal, resulting in superior catalytic ...

ABSTRACT In the present study, for the first time, a magnetic graphitic carbon nitride doped with selenium (Se-g-C3N4/Fe3O4) nanocomposite was designed and fabricated by incorporation of selenium to g-C3N4 via a facile thermal condensation technique and hybridization with Fe3O4 nanoparticles. The prepared Se-g-C3N4/Fe3O4 nanocomposite was then applied as ideal catalyst support for the immobilization of copper nanoparticles to prepare the Se-g-C3N4/Fe3O4/Cu nanocatalyst. The structure of Se-g-C3N...

Abstract Highly nitrogen-doped mesoporous carbon (N-mC) material incorporated cobalt oxide nanoparticles was synthesized through simple pyrolysis of environmentally friendly chitosan-polyaniline-Co(OAc)2 precursor in one-step. The as-prepared catalyst named CoO@N-mC with 14.65 wt% nitrogen content was characterized by different analysis techniques. The heterogeneous catalyst exhibits outstanding catalytic activity for the reduction of a variety of nitroaromatic compounds in the presence of NaBH4...

Magnetic mesoporous polymelamine formaldehyde nanocomposite-incorporating ZnO nanoparticles were successfully synthesized using solvothermal and sol–gel methods. Fourier-transform infrared spectrometry (FT-IR), X-ray diffraction, Brunauer–Emmett–Teller, vibrating sample magnetometer, thermogravimetric analysis, elemental analysis, transmission electron microscopy and field emission scanning electron microscopy techniques were then utilized for evaluation of nanocomposites. The as-prepared nanoco...

Abstract In the present study, in situ selenium-doped graphitic carbon nitride, showed as Se-g-C3N4, was prepared by applying low-cost melamine and 2,4,6-triselenocyanato-1,3,5-triazine as the precursor materials through a simple thermal condensation strategy and used as an ideal catalyst support. Ag NPs were anchored on the Se-g-C3N4 through the co-reduction method with NaBH4 as a reductant to fabricate the Se-g-C3N4/Ag nanocatalyst. Various microscopic and spectroscopic techniques confirmed th...

Abstract In this study, a novel nano catalyst consisted of Co oxide particles incorporated in N-doped porous carbon, named Co3O4@N-C-600, was synthesized in the one-step pyrolysis of polyaniline-graphitic carbon nitride composite grafted cobalt acetate at 600 °C. The resulting Co3O4@N-C-600 catalyst was characterized using different identification methods. In addition, specific surface area and the size of the porous carbon cavities were measured using Brunauer-Emmett-Teller (BET) analyzer. The ...
