Special Issue Information

Dear Colleagues,

Highly efficient electrocatalytic processes are expected to contribute solutions to current energy and environmental issues. Due to their low cost, high stability, tunable surface chemistry, desirable electrical and mechanical properties, as well as large accessible surface area, carbon materials are attractive materials for utilization in catalysts for electrocatalytic applications, such as those involved in energy storage and conversion, the removal of water pollutants and electrochemical sensors. Generally, carbon materials are the main component of electrocatalysts, typically being employed as a support for active phases, including metal oxides or noble metal nanoparticles. Carbon black and graphite have long constituted the preferred support in commercial carbon-based electrocatalysts, but novel nanostructured carbon materials such as graphene, graphene oxide, templated carbons and carbon nanotubes have attracted great interest and have contributed to the design of advanced electrocatalysts for various applications. Moreover, recent studies have revealed that carbon materials can act as catalysts without the need for metals, by doping them with heteroatoms or by creating carbon defects.

The present Special Issue of Nanomaterials aims to present novel electrocatalysts based on carbon materials. This Special Issue focuses on electrochemical reactions over carbon materials, such as the oxygen reduction reaction (ORR), hydrogen oxidation reaction (HOR), oxygen evolution reaction (OER), hydrogen evolution reaction (HER), CO2 reduction reaction (CO2RR), and nitrogen reduction reaction (NRR). As electrochemical reactions also occur in water treatment and sensing applications, studies focusing on the carbon materials employed in these applications are also welcome in this Special Issue. We invite authors to contribute original research articles and review articles addressing state-of-the-art progress in Carbon Nanomaterials for Electrocatalytic Applications.

Metal oxides containing La, Mn, and Co cations can catalyze oxygen reduction reactions (ORRs) in electrochemical processes. However, these materials require carbon support and optimal interactions between both compounds to be active. In this work, two approaches to prepare composites of La-Mn-Co-based compounds over carbon xerogel were developed. Using sol-gel methods, either the metal-based material was deposited on the existing carbon xerogel or vice versa. The metal oxide selected was the LaMn0.7Co0.3O3 perovskite, which has good catalytic behavior and selectivity towards direct ORRs. All the as-prepared composites were tested for ORRs in alkaline liquid electrolytes and characterized by diverse physicochemical techniques such as XRD, XPS, SEM, or N2 adsorption. Although the perovskite structure either decomposed or failed to form using those in situ methods, the materials exhibited great catalytic activity, which can be ascribed to the strengthening of the interactions between oxides and the carbon support via C-O-M covalent bonds and to the formation of new active sites such as the MnO/Co heterointerfaces. Moreover, Co-Nx-C species are formed during the synthesis of the metal compounds over the carbon xerogel. These species possess a strong catalytic activity towards ORR. Therefore, the composites formed by synthesizing metal compounds over the carbon xerogel exhibit the best performance in the ORR, which can be ascribed to the presence of the MnO/Co heterointerfaces and Co-Nx-C species and the strong interactions between both compounds. Moreover, the small nanoparticle size leads to a higher number of active sites available for the reaction. Full article

Metal–support interaction plays a critical role in determining the eventual catalytic activity of metals loaded on supporting substrates. This interaction can sometimes cause a significant drop in the metallic property of the loaded metal and, hence, a drop in catalytic activity in the reactions, especially in those for which low charge carrier transfer resistance is a necessary parameter. Therefore, there should be a case-by-case experimental or theoretical (or both) in-depth investigation to understand the role of support on each metal. Here, onto a layered porous carbon nitride (g-CN), we grew single crystalline Pt nanodisks (Pt@g-CN) with a lateral average size of 21 nm, followed by various characterisations such as electron microscopy techniques, and the measurement of electrocatalytic activity in the O2 reduction reaction (ORR). We found that intercalating Pt nanodisks in the g-CN interlayers causes an increase in electrocatalytic activity. We investigated the bonding mechanism between carbon support and platinum using density functional theory and applied the d-band theory to understand the catalytic performance. Analysis of Pt’s density of states and electronic population across layers sheds light on the catalytic behaviour of Pt nanoparticles, particularly in relation to their thickness and proximity to the g-CN support interface. Our simulation reveals an optimum thickness of ~11 Å, under which the catalytic performance deteriorates. Full article
