“…The O−Co 3 S 4 /CP electrode can further yield the better cycling stability with 79 % initial capacitance maintained than 49 % initial capacitance of Co 3 S 4 /CP electrode after 4000 cycles at 2 A g −1 (Figure7 f). The excellent electrochemical performance of O−Co 3 S 4 /CP is due to the synergistic effects of O doping and hollow nanosheets, where O doping can not only increase the electrical conductivity but also enhance electrochemical reactivity and the hollow nanosheets can provide abundant surface active sites as well as shorten the diffusion length of electrolyte to improve electrochemical performance [42] …”

Cobalt sulfides can be considered as auspicious electrode materials for supercapacitors due to the good electrical conductivity and high reversible redox capability. In this study, the O‐doped Co3S4 hollow nanosheets supported on carbon paper (O−Co3S4/CP) are facilely prepared through a suppressed sulfurization method by using CP‐supported Co‐ZIF as the precursor and methanol as the solvent. The hollow nanosheets not only offer fast transport pathways but also provide abundant redox active sites. Furthermore, theoretical calculations indicate that the O doping can enhance the adsorption ability of OH− on O−Co3S4 with electrochemical activity and electrical conductivity improvement. Owing to the advantages of the appropriate composition and unique structure, the as‐made hollow structure O−Co3S4/CP shows a remarkable specific capacitance of 755 F g−1 at a current density of 1 A g−1, while a good rate performance of 65 % capacitance retention at 10 A g−1 can be reached. Moreover, the asymmetric supercapacitors assembled by O−Co3S4/CP and activated carbon electrodes yield an energy density of 21.3 Wh kg−1 with power density of 0.75 kW kg−1. The present work can offer a useful guidance for the exploitation of O doped cobalt sulfides hollow nanosheets for supercapacitors.

“…When the Au content of Au/Ti 3 C 2 is 0.94%, the average yield of NH 3 production is 30.06 µg h −1 mg −1 , and the FE is 18.34% at −0.2 V versus RHE. In addition, Liu et al [80] successfully prepared a high-performance catalyst using MXene as the carrier of precious metal Ru (denoted as Ru@MXene). In 0.1 m KOH electrolyte, the NH 3 yield of the Ru@MXene catalyst is 2.3 µmol h −1 cm −2 , furthermore, at −0.4 V (vs RHE) the FE is 13.13%.…”

The family of transition metal carbides, nitrides, and carbonitrides (collectively called MXenes) has been a thriving field since the first invention of Ti3C2Tx (MXene) in 2011. MXene is a new type of nanometer 2D sheet material, which exhibits great application potentials in various fields due to its multiple advantages such as high specific surface area, good electrical conductivity, and high mechanical strength. Electrocatalysis is regarded as the core of future clean energy conversion technologies, and MXene‐based materials provide inspiration for the design and preparation of electrocatalysts with high activity, high selectivity, and long loading life time. The applications of MXene‐based materials in electrocatalysis, including hydrogen evolution reaction, nitrogen reduction reaction, oxygen evolution reaction, oxygen reduction reaction, carbon dioxide reduction reaction, and methanol oxidation reaction are summarized in this review. As a crucial session regarding experiments, the current safer and more environmentally friendly preparation methods of MXene are also discussed. Focusing on the materials design and enhancement methods, the key challenges and opportunities for MXene‐based materials as a next‐generation platform in both fundamental research and practical electrocatalysis applications are presented. This account serves to promote future efforts toward the development of MXenes and related materials in the electrocatalysis applications.
