ABSTRACT
In summary, the precise
design of new OER catalysts bearing low cost and acid-resistance remains
challenging, thus inevitably hindering the rapid development of PEM
electrolyzer in the short run. This inspiring work demonstrates the
effectiveness of Fe incorporation in reducing the kinetic barrier of acidic OER
process by enhancing water adsorption and dissociation via regulating the
electrophilicity of surface oxygen, being of great reference value for
exploiting economic OER in acidic conditions. However, some key factors that
affect catalytic performance, such as hydrogen spillovers, reduction and
oxidation properties of catalysts, should be discussed. With respect to the future
research, more efforts are worthy to be
devoted to finding alternative non-toxic heteroatoms for the design of high-performance
satisfactory low-cost catalysts.
