Ammonia synthesis via the electrochemical method is an environmentally-friendly alternative to the Haber-Bosch process. In this work, carbon materials made from fresh cigarette filters were used as the working electrode for the electrochemical synthesis of ammonia. TiO₂ was found to exist in the hydrochar of cigarette filters with a mass loading of 0.8 wt%, and showed positive impact on the catalytic performance of the hydrochar. A decent NH₃ yield of 6.02 μg mg_cat.⁻¹ h⁻¹ and a FE of 8.96% were achieved at −0.1 V versus reversible hydrogen electrode (RHE) in N₂-saturated 0.05 M H₂SO₄. The design of experiments proved that TiO₂, which was contained in the hydrochar, indeed played a great role in the catalytic reaction of ammonia synthesis.

通过电化学方法合成氨是Haber-Bosch工艺的环保替代方案。在这项工作中，由新鲜香烟过滤嘴制成的碳材料被用作氨的电化学合成的工作电极。发现TiO ₂存在于香烟过滤嘴的炭中，其质量负载为0.8重量％，并且对炭的催化性能显示出积极的影响。体面的NH ₃产量为6.02μgmg_猫。相对于在N ₂饱和的0.05 MH ₂ SO _4中的可逆氢电极（RHE），在-0.1 V时达到^-1 h ^-1和FE为8.96％。实验设计证明，炭中所含的TiO ₂确实在氨合成的催化反应中发挥了重要作用。
