CuCo-MOF/MoS2 as a High-Performance Electrocatalyst for Oxygen Evolution Reaction
Metal–organic frame materials (MOFs) create ordered spatial structures through organic bridges and metal ion centers. This microstructure can effectively disperse the active centers. In this work, CuCo-MOF was firstly prepared by hydrothermal method and then physically mixed with MoS2. The prepared materials were applied to study the catalytic performance for oxygen evolution reaction (OER). The results show that the overpotential and Tafel slope of CuCo-MOF/MoS2 are 336 mV and 75 mV dec−1. The addition of MoS2 can effectively reduce the stacking of MOFs and increase the effective contact area with the reactants and promote charge/mass transport as well as enhance the catalytic activity. In addition, MoS2 has strong viscosity, and when it is mixed with MOF, the stability of the composite can be improved. The good OER performance of CuCo-MOF/MoS2 provides a reference for the exploration of a novel OER catalyst.
期刊介绍：
Electrocatalysis is cross-disciplinary in nature, and attracts the interest of chemists, physicists, biochemists, surface and materials scientists, and engineers. Electrocatalysis provides the unique international forum solely dedicated to the exchange of novel ideas in electrocatalysis for academic, government, and industrial researchers. Quick publication of new results, concepts, and inventions made involving Electrocatalysis stimulates scientific discoveries and breakthroughs, promotes the scientific and engineering concepts that are critical to the development of novel electrochemical technologies.
Electrocatalysis publishes original submissions in the form of letters, research papers, review articles, book reviews, and educational papers. Letters are preliminary reports that communicate new and important findings. Regular research papers are complete reports of new results, and their analysis and discussion. Review articles critically and constructively examine development in areas of electrocatalysis that are of broad interest and importance. Educational papers discuss important concepts whose understanding is vital to advances in theoretical and experimental aspects of electrochemical reactions.
