Hyroconversion of 4-Chlorophenol (4-CP) was induced via atomic hydrogen substitution and 0.5–2 M polydisperse cobalt nanoparticles (40–500 d.nm) which were synthesized via a modified-polyol route. The cobalt nanoparticles and hydrogen incursion in the 4-CP helped to enforce the hydroconversion (HDC) reaction of 4-CP. The reaction runs were conducted based on an initial 4-CP wastewater effluent concentration discharged from a pesticide company, different particle sizes, and reaction time. Also, NaOH was added as a proton scavenger to the reaction mixture in order to avoid catalyst-deactivation. Samples from the reactor were collected at different times in order to monitor the hydroconversion process. The Co-catalyst reduced the activation energy of the reaction, initiated the hydro-substitution reaction at an earlier time, as well as enhanced 4-CP hydroconversion. Of all the catalysts, the 2 M polydisperse-cobalt nanoparticles (PD-CoNPs) gave the best performance with a description that fits the desorption mechanism whose k_eqd value = 0.079.

4-氯苯酚 (4-CP) 的氢转化是通过原子氢取代诱导的，0.5-2 M 多分散钴纳米粒子 (40-500 d.nm) 是通过改性多元醇途径合成的。4-CP 中的钴纳米颗粒和氢侵入有助于加强 4-CP 的加氢转化 (HDC) 反应。反应运行是根据农药公司排放的初始 4-CP 废水排放浓度、不同的粒径和反应时间进行的。此外，将NaOH作为质子清除剂加入到反应混合物中以避免催化剂失活。在不同时间收集来自反应器的样品以监测加氢转化过程。助催化剂降低了反应的活化能，提前引发了加氢取代反应，以及增强的 4-CP 加氢转化。在所有催化剂中，2 M 多分散钴纳米粒子 (PD-CoNPs) 的性能最好，描述符合解吸机制，其k _eqd值 = 0.079。
