Graphite/β-PbO2 Composite Inert Anode Synthesis Using Electrochemical Methods

Electrochemical Degradation of the Reactive Red 141 Dye on a β-PbO2 Anode Assessed by the Response Surface Methodology

A degradação eletroquímica do corante Vermelho Reativo 141 foi investigada por meio da aplicação da metodologia de superfície de respostas, utilizando reator filtro-prensa com anodo de β-PbO 2 . A carga requerida para 90% de descoloração (Q) e a remoção da demanda química de oxigênio após 30 min de eletrólise (COD) foram utilizadas para modelar o sistema. As variáveis investigadas foram a densi...

Sonoelectrochemical mineralization of perfluorooctanoic acid using Ti/PbO2 anode assessed by response surface methodology

BACKGROUND Perfluorocarboxylic acids (PFCAs) are emerging pollutant and classified as fully fluorinated hydrocarbons containing a carboxylic group. PFCAs show intensively resistance against chemical and biological degradation due to their strong C-F bond. The Sonoelectrochemical mineralization of the synthetic aqueous solution of the perfluorooctanoic acid (PFOA) on Ti/PbO2 anode was investigat...

Synthesis of uniform TiO2@carbon composite nanofibers as anode for lithium ion batteries with enhanced electrochemical performance

Enhanced electrochemical performance promoted by monolayer graphene and void space in silicon composite anode materials

The high specific capacity battery electrode materials have stimulated great research interest. Silicon (Si) as a low-cost abundant material with a theoretical specific capacity of 4200 mA h g , offers an attractive option for the low-cost next-generation high capacity Li-ion batteries anode. However, successful applications of silicon anode have been impeded by several limitations such as larg...

Facile synthesis and electrochemical performances of hollow graphene spheres as anode material for lithium-ion batteries

UNLABELLED The hollow graphene oxide spheres have been successfully fabricated from graphene oxide nanosheets utilizing a water-in-oil emulsion technique, which were prepared from natural flake graphite by oxidation and ultrasonic treatment. The hollow graphene oxide spheres were reduced to hollow graphene spheres at 500°C for 3 h under an atmosphere of Ar(95%)/H2(5%). The first reversible spec...
