Special Issue Information

Dear Colleagues,

Electrocatalysis is a crucial process that plays a vital role in many energy conversion and storage technologies, including water electrolysis, CO2 capture and utilization, fuel cells, and metal–air batteries. In recent years, there has been significant interest in developing advanced electrode materials with high electrocatalytic performance for efficient and sustainable energy conversion and storage. These materials should possess excellent catalytic activity, selectivity, stability, and durability under various reaction conditions.

This Special Issue focuses on the recent advances in high electrocatalytic performance electrode materials for energy conversion and storage applications. The aim is to provide a comprehensive overview of the latest developments in the synthesis, characterization, and performance evaluation of various electrode materials for different electrocatalytic reactions, including the oxygen reduction reaction (ORR), oxygen evolution reaction (OER), hydrogen evolution reaction (HER), carbon dioxide reduction reaction (CO2RR), etc.

The papers in this Special Issue will cover a wide range of topics, including the design and synthesis of novel electrode materials, the use of advanced characterization techniques to understand the structure–property relationship of electrode materials, and the development of efficient strategies for improving the electrocatalytic activity and stability of existing materials. The ultimate goal is to accelerate the development of sustainable and efficient energy conversion and storage technologies.

Abstract
The development of non-noble-metal-based electrocatalysts for water electrolysis is essential to produce sustainable green hydrogen. Highly active and stable non-noble-metal-based electrocatalysts are greatly needed for the replacement of the benchmark electrocatalysts of iridium, ruthenium, and platinum oxides. Herein, we synthesized non-noble-metal-based, Fe-doped, β-Ni(OH) [...] Read more.
The development of non-noble-metal-based electrocatalysts for water electrolysis is essential to produce sustainable green hydrogen. Highly active and stable non-noble-metal-based electrocatalysts are greatly needed for the replacement of the benchmark electrocatalysts of iridium, ruthenium, and platinum oxides. Herein, we synthesized non-noble-metal-based, Fe-doped, β-Ni(OH)2 interconnected hierarchical nanosheets on nickel foam via a conventional hydrothermal reaction. Iron doping significantly modified the electronic structure of β-Ni(OH)2 due to the electron transfer of iron to nickel hydroxide. Fe-doped β-Ni(OH)2 was investigated both as a cathode and anode electrode for hydrogen and oxygen evolution reactions (OERs and HERs). It facilitated significant improvements in electrochemical performance due to its huge intrinsic active sites and high electrical conductivity. As a result, the electrocatalytic activity of Fe-doped Ni(OH)2 exhibited a lesser overpotential of 189 and 112 mV at a current density of 10 mA cm−2 and a Tafel slope of 85 and 89 mV dec−1 for the OER and HER, respectively. The Fe-doped β-Ni(OH)2 displayed excellent durability for 48 h and a cell voltage of 1.61 V @ 10 mA cm−2. This work demonstrates that Fe-doped β-Ni(OH)2 is an efficient electrocatalyst with superior electrocatalytic performance towards overall water splitting that can be useful at the industrial scale.
