Special Issue Information

Dear Colleagues,

Carbon gels are attractive three-dimensional structures that can confine small molecules within the cavities of their porous framework, as well as exhibit remarkable electrical conductivity. The mostly mesoporous nature of their porous texture enables specific advantages of the carbon gels when compared to other carbonaceous materials. Typically formed via the carbonization of a previously assembled polymeric network in the presence or absence of templates, these carbon gels possess unique properties, such as low density, high surface area, excellent electrical conductivity, and fast diffusion capability for the confined molecules, among others. However, the synthesis of carbon gels often involves complex, time-consuming, and energy-intensive processes, which can hinder their scalability and competitiveness within the industrial field. Advances in terms of fabrication performance, such as the combination with metallic or carbon-based additives, the doping of the micro- or nano-structure with heteroatoms, or the implementation of technologically sophisticated processes, have enabled the application of carbon gels in a wide scope of disciplines, such as energy conversion and storage, environmental remediation, and electroanalysis via piezoelectric, optical, and electrochemical sensors.

This Special Issue, entitled “Advances in Carbon Gels: From Synthesis to Electrochemical and (Bio)analytical Applications”, aims to highlight recent developments in the synthesis, characterization, and applicability of carbon gels through the use of innovative approaches. Original research articles, reviews, letters, and mini reviews covering these topics or similar topics are welcome.

In energy applications, the use of materials with hierarchical porous structures and large surface areas is essential for efficient charge storage. These structures facilitate rapid electron and ion transport, resulting in high power density and quick charge/discharge capabilities. Carbon-based materials are extensively utilized due to their tunable properties, including pore sizes ranging from ultra- to macropores and surface polarity. Incorporating heteroatoms such as nitrogen, oxygen, sulfur, phosphorus, and boron modifies the carbon structure, enhancing electrocatalytic properties and overall performance. A hierarchical pore structure is necessary for optimal performance, as it ensures efficient access to the material’s core. The microstructure of carbon materials significantly impacts energy storage, with factors like polyaromatic condensation, crystallite structure, and interlayer distance playing crucial roles. Carbon aerogels, derived from the carbonization of organic gels, feature a sponge-like structure with large surface area and high porosity, making them suitable for energy storage. Their open pore structure supports fast ion transfer, leading to high energy and power densities. Challenges include maintaining mechanical or structural integrity, multifunctional features, and scalability. This review provides an overview of the current progress in carbon-based aerogels for energy applications, discussing their properties, development strategies, and limitations, and offering significant guidance for future research requirements.
