A simple technique for preparing carbon encapsulated La and Eu nanoparticles

Uniform surface modification of diatomaceous earth with amorphous manganese oxide and its adsorption characteristics for lead ions

“…Firstly, The DE powders were coated by a carbon layer through thermal-carbonization of adsorbed glucose which has been successfully applied to produce carbon encapsulated core-shell materials [13,14]. After the carbon-coated diatomaceous earth (C@DE) was dispersed in KMnO 4 solution, MnO 2 grew on the surface of C@DE as a result of the following redox reaction: [15] …”

Synthesis of carbon-encapsulated iron nanoparticles by pyrolysis of iron citrate and poly(vinyl alcohol): a critical evaluation of yield and selectivity

“…Magnetic nanoparticles encapsulated in carbon or passivated by tight oxide layers can also be produced in a continuous way by laser pyrolysis of organometallics [17][18][19]. In order to simplify the production protocol of magnetic CEs several groups have tried to use conventional pyrolysis reactions that can be conducted in laboratory ovens in which the gas temperature does not exceed 1000-1200 • C. The main idea behind the pyrolysisbased process is the thermal treatment of metal and carbon precursors with the expectation that the as-formed metal nanoparticles will encapsulate in carbon [20][21][22][23][24][25][26][27]. Another approach involves the deposition of carbon layers (via thermal decomposition of hydrocarbons) onto previously prepared magnetic nanoparticles [28,29].…”

Classification of carbon nanostructure families occurring in a chemically activated arc discharge reaction

“…The dark particles embedded in a carbon matrix are most probably the gadolinium carbides and their formation has been already reported in previous publications on the arc discharge of various metal oxides. [48][49]…”
