Advanced Nanocatalysts for Electrochemical Energy Storage and Generation: Batteries, Supercapacitors, Electrolyzers and Fuel Cells

The development of nanomaterials for electrochemical energy storage and generation is gaining increased attention world-wide. Electrochemical devices include batteries supercapacitors, electrolyzers and fuel cells. The development of functional, active and electrochemically stable nanomaterials is highly important to advance the commercial capability of these devices Commercial development is particularly imperative for alkaline fuel cells and electrolyzers, considering the increase in research in recent years as an outcome of the development of anion exchange membranes. Highly active nanomaterials are also needed for rechargeable batteries and supercapacitors. Experimental evaluation techniques such as in situ Fourier-transform infrared spectroscopy (FTIR), and differential electrochemical mass spectrometry (DEMS), provide valuable insights into the electrochemical reactions taking place on novel nanomaterials, leading to the determination of reaction mechanisms. The design of nanostructured catalysts by application of powerful ab initio calculations is also highly relevant. This JMR Focus Issue will review the state of the art and accelerate fundamental understandings of nanostructured materials used in alkaline fuel cells (hydrogen or alcohols as fuels) and electrolyzers, rechargeable batteries and supercapacitors. Contributions are solicited on experimental and theoretical studies of novel nanostructured materials for such electrochemical devices. Manuscripts are solicited in the following areas: • Advanced nanostructured anodes and cathodes for anion exchange membrane fuel cells • Novel nanocatalysts for alkaline direct alcohol fuel cells • Development of new nanocatalysts for alkaline electrolyzers • Novel active nanomaterials for supercapacitors • Advanced active nanomaterials for rechargeable batteries
