The article discusses the importance of developing cost-effective electrocatalysts for urine electrolysis to improve energy efficiency in hydrogen production. Traditional methods like urea oxidation reaction (UOR) face challenges due to high thermodynamic barriers and competition with the oxygen evolution reaction (OER). By proposing a kinetic favorable Cl-mediated UOR pathway, the article suggests a promising solution for the cost-effective production of hydrogen. Acidic urine electrolysis is highlighted as a method to avoid harmful byproducts, improve performance, and reduce electricity costs for hydrogen production. The optimized Pt-catalyzed urine electrolysis process is shown to have a lower electricity cost compared to traditional methods, making it a viable option for practical applications in hydrogen production.
