Electrochemical Water Splitting

Water splitting plays an important role in electrochemical and photoelectrochemical conversion of energy devices. Electrochemical water splitting by the hydrogen evolution reaction (HER) is a straightforward route to produce hydrogen (H2), which requires an efficient electrocatalysts to minimize energy consumption. Recent advances have created a rapid rise in new electrocatalysts, particularly those based on non-precious metals. In this review, we present a comprehensive overview of the recent developments of ternary and quaternary 6d-group transition metal chalcogenides (TMCs) based electrocatalysts for water splitting, especially for HER. Detailed discussion is organized from binary to quaternary TMCs including, surface engineering, heterostructures, chalcogen substitutions, and hierarchically structural design in TMCs. Moreover, emphasis is placed on future research scope and important challenges facing these electrocatalysts for further development in their performance towards water splitting.

Energy Demands

In the context of even more growing energy demands, the investigation of alternative environmentally friendly solutions, like fuel cells, is essential. Given their outstanding properties, carbon nanohorns (CNHs) have come forth as promising electrocatalysts within the nanocarbon family. Carbon nanohorns are conical nanostructures made of sp2 carbon sheets that form aggregated superstructures during their synthesis. They require no metal catalyst during their preparation and they are inexpensively produced in industrial quantities, affording a favorable candidate for electrocatalytic reactions. The aim of this article is to provide a comprehensive overview regarding CNHs in the field of electrocatalysis and especially, in oxygen reduction, methanol oxidation, and hydrogen evolution, as well as oxygen evolution from water splitting, underlining the progress made so far, and pointing out the areas where significant improvement can be achieved.

Background: A Book Review on Layered Materials for Energy Storage and Conversion Edited by Dongsheng Geng, Yuan Cheng and Gang Zhang, The Royal Society of Chemistry, 2019, 315 Pages, Print ISBN 978-1-78801-426-7, Print ISSN 2046-0066, DOI: 10.1039/9781788016193-FP001 In the earlier decade, the extensive research hot-spot in two-dimensional (2D) layered materials, especially graphene, metal-organic frameworks (MOFs) and transition metal dichalcogenides (TMDCs) benefiting of their exceptional chemical, physical, optical, mechanical and electronic properties. This book provides an up-to-date comprehensive overview of synthesis approaches and functionalization routes of graphene and TMDCs and functional properties of intercalated layered materials and its energy applications. Methods: The chemistry of layered two-dimensional materials towards its allied applications in electrocatalysis, lithium-ion batteries, sodium-ion batteries, thermoelectric materials, water-splitting and performance of photovoltaic devices are the core issues of energy storage and conversion and they are well addressed in this book. Results: This book consists of nine chapters. Altogether they discuss layered materials, energy storage, substitute energy storage and conversion specifically as it is not possible to discuss each and everything in detail. The chapters are written well by the reputed experts around the globe. That makes this book an outstandingly important and reliable sources of information. It is valuable for a book to provide updated information, review the work done till date, do proper analysis, compare the pros and cons of comparable existing technologies and guide the readers to the research gaps and places where improvement is required. Conclusion: This book is an essential reference guide for students, researchers, engineers and professionals in advanced materials community and energy-related sectors such as photovoltaics, water-splitting, supercapacitor, and batteries, etc.
