Study of Microwave Heating Effect in the Behaviour of Graphene as Second Phase in Ceramic Composites

The choice of the right material is essential in microwave processing. The carbon materials are good microwave absorbers, which allows them to be transformed by microwave heating into new carbon materials with adapted properties, capable of heating other materials indirectly. In this paper, the microwave heating of graphene as reinforcement of the lithium aluminosilicate (LAS) ceramics has been explored. LAS ceramics have a near-zero coefficient of thermal expansion and exhibit an effective and efficient heating by microwave. Nevertheless, we have found that the graphene did not show any significant response to the microwave radiation and, hence, the interaction as mechanical reinforcement with the LAS material is harmful. The possible benefits of graphene materials to microwave technology are widely known; however, the mechanism involved in the interaction of microwave radiation with ceramic-graphene composites with high dielectric loss factors has not been addressed earlier.

Carbon nanospheres as an electrode material for electroadsorption of Cu (II)

Objectives. Contamination with heavy metals has augmented in last decades due to several factors. So, scientific community has a challenge to develop new and more efficient methods for contaminants removal. Electroadsorption is one of investigated techniques with promising results. The main challenge with this technique is determination of optimal parameters, such as electrode material, time and conditions of adsorption. Material for electrode for electroadsorption must fulfil some criteria: high electroactive area, low electrical resistance and environmental compatibility. For that reason, our research group decided to synthetize a set of new carbon materials with high surface area and features than make them interesting to test them as an electrode material. Methodology. 3 carbon materials were synthetized by sol-gel method using different time and temperature conditions. All materials were characterized by scanning electron microscopy and other techniques. FTO glasses were modified with synthetized materials separately. Electroadsorption of Cu (II) was conducted at room temperature. Contribution. In this work we demonstrate an easy synthesis of 3 carbonaceous materials with high surface area capable to remove Cu (II) from water solution by electroadsorption.

New carbon for electrochemical energy storage and conversion

The advancement of clean electrochemical technologies is highly related to the development of novel active materials. Especially, new carbon materials are playing great roles in the electrochemical energy storage and conversion devices. Herein, we discuss the recent progress on new carbon materials from several important aspects including new mold carbon sources, novel high-efficiency puffing method, tailored carbon arrays morphologies (vertical graphene and carbon nanotubes branch), and modified heteroatom (N and S)-doped carbon materials. Our perspective may shed a light on further study on new carbon materials for applications in energy storage and conversion.
