    摘要:

    尿素电解可以将富含尿素废水中的尿素转化为氢气,用于环境保护和可持续能源生产。电催化尿素氧化反应(UOR)因其较低的平衡电位,在替代析氧反应(OER)提高阴极产氢方面具有广阔的应用前景。传统尿素电解工艺存在能耗高,过电位高,稳定性差等诸多劣势,因此开发高性能的催化剂对尿素电解尤为关键。本研究通过水热法制备的高性能的NiCo-LDHs/VMT催化剂,在电流密度为 10 mA·cm?2,电位为1.35 V的条件下可以高效电解尿素产生氮气,在-0.225 V的电位条件下高效电解尿素产生氢气,实现高效电解尿素。结果表明该方法能为尿素电解工业化提供思路,并为新疆蛭石资源高附加值利用以及高效设计尿素电解催化剂提供一定的指导意义。

    Abstract:

    Urea electrolysis offers a promising approach for converting urea-rich wastewater into hydrogen, contributing to environmental preservation and sustainable energy production. The electrocatalytic urea oxidation reaction (UOR) holds great potential in replacing the oxygen evolution reaction (OER) for enhancing cathodic hydrogen evolution due to its lower equilibrium potential. However, conventional urea electrolysis processes suffer from drawbacks such as high energy consumption, high overpotential, and poor stability, necessitating the development of high-performance catalysts. In this study, a superior NiCo-LDHs/VMT catalyst prepared via a hydrothermal method exhibited efficient urea electrolysis, producing nitrogen gas under a current density of 10 mA·cm-2 and a potential of 1.35 V, as well as hydrogen gas under a potential of -0.225 V. These results demonstrate the potential of this method for industrial-scale urea electrolysis, providing insights for the high-value utilization of zeolite resources in Xinjiang and the efficient design of urea electrolysis catalysts.
