Special Issue Information

Dear Colleagues,

Oxygen evolution reaction (OER), as a fundamental half-reaction, is involved in water splitting and rechargeable metal-air batteries. While, the sluggish kinetics of its four-electron transfer process becomes a bottleneck to the performance enhancement. Thus, rational design and synthesis of electrocatalysts is of vital significance for boosting OER performances. Recently, developments and breakthroughs in experimental achievements on OER electrocatalysts are revealed. More perspectives and future directions are noticed and popular for further electrocatalytic performance enhancement and deeper understanding of design for electrocatalysts and principles. Here, extensive efforts are welcomed, which involves the following aspects:

(i) The novel synthesis of noble or non-noble metal electrocatalysts for boosting OER performances.
(ii) The deeper insights of the understanding on theoretical calculations for OER;
(iii) The efficient OER electrocatalysts that show outstanding OER performances for water splitting or metal-air batteries.

Significant research has focused on cost–effective, highly active, and exceptionally stable non–noble metal electrocatalysts (NNMEs) to boost the performance of the oxygen reduction reaction (ORR). Of note, the development of design and synthesis of Fe–N–C electrocatalysts is essential but remains challenging. Herein, the Fe and N co–doped porous carbon material with a yolk–shell (YS) structure, termed SA–H2TPyP@PDA–Fe (900), was fabricated by self–assembly of metal–free porphyrin as a yolk and polymerization of dopamine as a shell with an addition of iron salts, followed by the high–temperature pyrolysis and acid–leaching. As a result, active sites, like FeN4 and N–doped C, within rich porous YS carbon structures, play an important role for ORR in an alkaline media. The SA–H2TPyP@PDA–Fe (900) electrocatalyst shows positive ORR performances than those of SA–H2TPyP (900) and SA–H2TPyP@PDA (900), indicating the dominating function of the YS carbon structure decorated with Fe–based species. This efficient route of template–free–induced preparation of the YS structure discovers the design and synthesis of NNMEs for ORR. Full article
