Abstract: The widespread adoption of renewable energy demands reliable energy storage solutions, which are currently held back by issues related to performance, cost, and/or ease of use. To tackle these issues, researchers have explored two-dimensional (2D) materials as cost-effective, high-performance electrocatalysts and electrode materials. Among these 2D materials, MXenes, a distinct category of carbides and nitrides, have gained prominence owing to their exceptional tunability, conductivity, and high surface area-to-volume ratio. Nitride MXenes (MNenes), in particular, excel in these properties compared to their carbide counterparts, but their synthesis method remains unclear. In this presentation, I will introduce the oxygen-assisted molten salt fluoride etching synthesis method developed in our laboratory, enabling the production of phase-pure MNene materials. Furthermore, I will delve into the enhanced performance of these MNenes for the nitrogen reduction reaction (NRR), carbon dioxide reduction reaction (CO2RR), hydrogen evolution reaction (HER), and applications pertaining to energy storage. Additionally, I will provide real-time mechanistic insights into the underlying mechanisms of each system. Moreover, I will illustrate how integrating this research with national and international outreach initiatives has significantly enriched diversity within the College of Engineering at Texas A&M University. I will specifically discuss the summer research program initiated for undergraduate students from historically black colleges and universities, as well as the U.S-Africa collaborations forged through the National Academy of Science fellowship. I will wrap up by discussing some future directions and opportunities for MNenes in catalysis and energy storage, emphasizing their potential impact on advancing these fields.
