About this Research Topic
Electrocatalytic energy conversion has been considered as one of the most promising pathways to realize high-efficiency energy conversion to face the energy crisis. Specific electrocatalysts with high activity, superior stability, low cost, and high selectivity are urgently needed for various energy conversion routes with multiple targets, including hydrogen evolution reaction (HER), oxygen evolution reaction (OER), oxygen reduction reaction (ORR), hydrogen oxidation reaction (HOR), methanol oxidation reaction (MOR), urea oxidation reaction (UOR), nitrogen reduction reaction (NRR), CO2 reduction reaction (CO2RR), electrocatalytic organic synthesis, and other energy-related processes. Two-dimensional (2D) catalysts in particular have drawn substantial attention due to their large surface area, facile 2D charge transport pathway, and ease in structural and electronic modulations, which shed light on further optimization of the catalytic performances for energy conversion. Thus, designing highly efficient energy electrocatalysts with 2D configuration is highly desirable.
Effective microstructure design has been widely used to improve the catalytic activity and selectivity of 2D electrocatalysts, which is based on enriching the catalytic active sites, or equivalently, facilitating the in-situ generation of the active species. In addition, the intrinsic activity of the 2D electrocatalysts could be optimized by regulating their electronic structures, as well as optimizing the charge transport behaviors via microstructure design. Furthermore, as a simplified material platform, 2D electrocatalysts could be utilized to understanding the reaction mechanisms via theoretical calculations and in situ experimental techniques such as in situ AFM, in situ Raman spectroscopy, in situ IR spectroscopy, etc., thereby re-directing the material design for higher performance.
