Thioacetamide-derived nitrogen and sulfur co-doped carbon nanoparticles used for label-free detection of copper(ii) ions and bioimaging applications

Abstract

Thioacetamide-derived nitrogen and sulfur co-doped carbon nanoparticles as photoluminescent probes for the efficient detection of Cu2+ ions.

Synthesis and photocatalytic CO2 reduction performance of aminated coal-based carbon nanoparticles

“…The high magnification TEM image (inset) shows that the surface of the CNPs has clear lattice strips. The spacing between the strips is 0.21 nm, close to the (100) plane of graphite, 20 indicating that the coal-based CNPs have a graphite-like crystalline carbon structure. It can be seen from Fig.…”

A comparative study on the preparation methods and properties of coal‐based fluorescent carbon nanoparticles

“…TEM results (Figure B‐D) of the FCNPs reveals that the FCNPs obtained by different methods are all spherical particles of less than 10 nm, with good dispersibility, and the particle size of the products is FCNPs‐HE (Figure C) > FCNPs‐AO (Figure B) > FCNPs‐OS (Figure D). High‐resolution transmission electron microscopy (HRTEM) results (inset in each figure) show FCNPs‐AO prepared by mixed acid/ultrasonic oxidation method is a hollow annular spherical particle with a graphite‐like lattice fringe on the ring wall, and the lattice spacing is 0.21 nm, close to the (100) crystal surface of the graphite. FCNPs‐HE and FCNPs‐AO, obtained by H 2 O 2 etching method and the organic solvent/ultrasonic extraction method, respectively, are solid spherical particles, and the surface has a lattice fringes represent for crystal surface of the graphite.…”

Ultrasonically Induced Sulfur-Doped Carbon Nitride/Cobalt Ferrite Nanocomposite for Efficient Sonocatalytic Removal of Organic Dyes

“…ZnS-NPs-AC, TiO 2 , MgO ZnO, ZnS, Cu 2 S, CdS, MIL-101(Cr)/RGO/ZnFe 2 O 4 and CoFe 2 O 4 @ZnS have been used for sonocatalytic degradation of organic dyes [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22].…”
