Special Issue Information

Dear Colleagues,

The increase of global warming issues caused by greenhouse gases emissions related to low efficient conversion processes and chemical industry processes is becoming everyday more impactful on our lives and on the environment. To reduce these emissions, the use of renewable energy sources must become prominent in the near future. Over the past years, the cost of electricity generated from wind and solar has fallen 67% and 86%, respectively, and is now competitive to fossil fuel-based electricity generation technologies. This electric cost reduction opens a huge opportunity for the electrification of the chemical industry. In order to efficiently convert and store the energy from renewables, electrochemical processes are essentials. At the same time, the energy from renewables can be conveniently utilized to produce complex organic chemicals from biomass, CO2 and other simple molecules.

In this view, electrocatalysts plays a crucial role, since they enable the lowering of the overpotentials needed for the operation of electrochemical devices. 

At the same time, it is necessary to stay away, as much as possible, from the massive use of noble metals for the manufacturing of catalysts, due to their high cost and low earth-abundance, which could cause exaggerate cost rising and raw materials supply issues.

This Special Issue on “Electrocatalysts for Sustainable Energy and Chemical Synthesis Applications” welcomes the submission of manuscripts in the form of original research articles, short communications, and reviews. The topics include noble metal-free catalysts for all types of electrochemical reactions involved in energy conversion and storage devices (batteries, fuel cells, electrolyzers, etc.) and catalysts for electrochemical synthesis processes. Examples are electrocatalysts for oxygen reduction, oxygen evolution, hydrogen evolution, organic molecules oxidation, electrochemical hydrogenation, ammonia electrosynthesis and CO2 electroreduction reactions.

Insights on innovative catalysts synthesis strategies and materials characterization, as well as correlation between materials properties and electrocatalytic activity and catalysts durability are particularly welcome. Furthermore, the use of innovative techniques for electrode production able to control nanostructured properties are also kindly invited.

With the assistance of surfactant, Fe nanoparticles are supported on g-C3N4 nanosheets by a simple one-step calcination strategy. Meanwhile, a layer of amorphous carbon is coated on the surface of Fe nanoparticles during calcination. Transmission electron microscopy (TEM), scanning electron microscope (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and inductively coupled plasma (ICP) were used to characterize the morphology, structure, and composition of the catalysts. By electrochemical evaluate methods, such as linear sweep voltammetry (LSV) and cyclic voltammetry (CV), it can be found that Fe25-N-C-800 (calcinated in 800 °C, Fe loading content is 5.35 wt.%) exhibits excellent oxygen reduction reaction (ORR) activity and selectivity. In 0.1 M KOH (potassium hydroxide solution), compared with the 20 wt.% Pt/C, Fe25-N-C-800 performs larger onset potential (0.925 V versus the reversible hydrogen electrode (RHE)) and half-wave potential (0.864 V vs. RHE) and limits current density (2.90 mA cm−2, at 400 rpm). In 0.1 M HClO4, it also exhibits comparable activity. Furthermore, the Fe25-N-C-800 displays more excellent stability and methanol tolerance than Pt/C. Therefore, due to convenience synthesis strategy and excellent catalytic activity, the Fe25-N-C-800 will adapt to a suitable candidate for non-noble metal ORR catalyst in fuel cells. Full article
