Nanostructured carbon materials obtained by green synthesis concepts

J. Parmentier, C. Matei Ghimbeu, J.-M. Le Meins, L. Delmotte, C. Vix-Guterl

The simultaneous control of porosity, morphology, surface chemistry and structure of carbon materials are of prime importance in several application fields. The design of such materials requires a good control of classical synthesis routes but also, in some cases, the development of new and original synthesis pathways. In this case, the understanding of the formation mechanisms of these carbons is required to obtain materials with well-tailored physico-chemical features. These mechanisms concern the soft-template route, the thermal and laser pyrolysis, wood welding, graphitization assisted by catalysis, hydrothermal synthesis and shaping of carbon (or hybrid carbon) materials.

In this framework, we developed original environmentally-friendly synthesis approaches combining biosourced carbon precursors, soft-synthesis conditions (limited temperature and normal pressure), less corrosive reagents and reduced number of synthesis steps (“one-pot” synthesis)

Understanding the performances of carbon materials used in adsorption and energy storage


C. Matei Ghimbeu, J. Dentzer, R. Gadiou, J.-M. Le Meins, J. Parmentier, B. Rety, C. Vix-Guterl

To understand the influence of each physico-chemical characteristic of carbon on their performances (adsorption/storage capacity, selectivity, stability during electrochemical cycling…), an original approach was developed consisting of a systematic variation of one characteristic of the material (texture, structure, functionalities) keeping, as far as possible, the others unchanged. This strategy, requiring deep knowledge of the formation/modification mechanisms of carbons, enabled correlations between carbon characteristics and their performances to be established. Indeed, we could demonstrate that the active surface area (ASA) is the key parameter influencing the irreversible capacity of Li and Na+ ion batteries as well as the capacitance of supercapacitors.

Another important objective is to understand the interactions of carbon materials with their environment (gas, liquid, solid) in conditions similar to their application. For this purpose, specific characterization techniques were developed in our laboratory, such as TPD-MS (temperature programmed desorption coupled to mass spectrometry). This technique was able to identify and quantify the surface chemistry of carbon materials, study their affinity with certain molecules and even study the pyrolysis process of carbon precursors. Combined with other complementary techniques like XPS (X-ray photoelectron spectroscopy) and physisorption analysis (N2, CO2, H2O, COVs) led to an understanding of the nature of the interaction with their environment and  improved performances in applications such as pollutant removal from water (amoxicillin, chlorinated hydrocarbons, pesticides…) and from air (NOx, COVs),  gas storage and gas separation (H2, CO2 and CH4).

Development of hybrid carbon materials (C/M and C/MXn, X=C, N, O, S) via the confinement of metal- based nanoparticles (NPs) in carbon

C. Matei Ghimbeu, J. Parmentier, J.-M. Le Meins, C Vaulot, L Delmotte, C. Vix-Guterl

The addition of a second phase to the carbon framework enabled the introduction of new functionalities and therefore an extension of their application fields or an improvement of their performances. Hybrid materials, combining a carbon matrix (porous or not) and metal (M)-based nanoparticles (NPs) were developed. Depending on the synthesis conditions it is possible to control the carbon characteristics (mesoporosity, surface functionalities, structure…) but also those of NPs, such as :

  • Chemical nature (metal (Pd, Co), alloys (PdxM1-x), metal oxides and non-oxides (SnO2, GeO2 ,TiO2, CrN, WC, WS, LiFePO4)
  • Location (in the pores, in the wall or on the external surface of carbon)
  • Size and dispersion

The CHM team has most notably developed the “one-pot” soft-template approach with the in situ formation of NPs during the carbonization of a mixture of carbon precursor/surfactant/metallic salt. These NPs, confined in carbon matrix and/or in carbon mesoporosity, appear accessible to fluids/electrolytes via the opened porosity. This confinement leads to different behaviour and performances of the materials compared to those obtained by classical infiltration of NPs into the carbon matrix.

Nanoparticles (NPs) confinement in carbon for gas and energy storage applications

 C. Matei Ghimbeu, J-M Le Meins, J. Parmentier,  L. Vidal, C. Vix-Guterl

Hybrid carbon materials present supplementary functionalities due to the presence of nanoparticles (NPs) which act as an active phase for electrochemical, catalytic, magnetic or absorption applications. Interestingly, these biphasic materials exhibit specific behaviours due to the in situ growth of the NPs and specifically derived structure (good dispersion of NPs in the carbon walls or pores, crystalline growth directed by confinement, accessibility of NPs). The objective is to understand the synergy observed for these nanocomposites carbon/NPs to improve performances in applications such as hydrogen storage (metallic hydride formation) or electrochemical energy storage (Li and Na batteries, supercapacitors).
