【#Tech24H】Green hydrogen refers to hydrogen produced by electrolyzing water using renewable energy. Researchers have long sought to improve hydrogen production efficiency, with the urea oxidation reaction considered a promising alternative pathway. However, the traditional urea oxidation reaction tends to produce nitrogen gas, posing significant challenges for selectively steering the reaction toward the target product, nitrite. Recently, Inner Mongolia University has made a major breakthrough in energy-efficient green hydrogen production coupled with the generation of high-value-added chemicals. The research team proposed an innovative catalyst design strategy, successfully creating an efficient multifunctional electrocatalyst. This catalyst redirects the reaction pathway toward the production of high-value-added nitrite while synergistically generating hydrogen, simultaneously and significantly suppressing the undesired nitrogen gas byproduct. This achieves the efficient conversion of urea into nitrite with economic feasibility, holding promise for advancing the industrial-scale production of green hydrogen.
