In this study, we investigated the oxidative decomposition of NH<sup>4+<\/sup> with O<sub>3<\/sub> at 333 K in the presence of a homogeneous Co<sup>2+<\/sup> catalyst and Cl<sup>&#8211;<\/sup> in the wide pH range of the test solution. The reaction behavior was greatly affected by pH of the test solution. In a basic solution at pH 12, high conversion of NH<sup>4+<\/sup> was obtained even in the absence of Co<sup>2+<\/sup> and Cl<sup>&#8211;<\/sup>, and the main product was NO<sup>3-<\/sup>. However, Co<sup>2+<\/sup> and Cl<sup>&#8211;<\/sup> in the solution greatly enhanced the decomposition rate of NH<sup>4+<\/sup> in acidic to mild basic solutions (pH 1\u20138), while only low conversion of NH<sup>4+<\/sup> was observed unless both Co<sup>2+<\/sup> and Cl<sup>&#8211;<\/sup> were present. For the reaction with Co<sup>2+<\/sup> and Cl<sup>&#8211;<\/sup> in the solutions, NH<sup>4+<\/sup> was transformed mainly into chloramines (NH<sub>x<\/sub>Cl<sub>3x<\/sub>, x =1\u20133) by the reaction with HClO, which was formed by the reaction of Cl<sup>&#8211;<\/sup> with O<sub>3<\/sub> catalyzed by the homogeneous Co<sup>2+<\/sup> catalyst, and led to the high decomposition rate of NH<sup>4+<\/sup>. Cl<sup>&#8211;<\/sup> suppressed the formation of the precipitate CoO(OH) during the reaction and consequently the Co<sup>2+<\/sup> catalyst stably existed in the reaction solution, which was another reason for the high decomposition rate of NH<sup>4+<\/sup> in the presence of Cl<sup>&#8211;<\/sup>. Owing to the swift decomposition of NH<sup>4+<\/sup> under mild reaction conditions and small formation of secondary waste, the oxidative decomposition of NH<sup>4+<\/sup> in the presence of the homogeneous Co<sup>2+<\/sup> catalyst and Cl<sup>&#8211;<\/sup> is suitable and applicable for the treatment of the aqueous liquid waste containing ammonium salts and nitric acid.\n<\/li>\n<li>\n<b>&#8220;Ultrahigh-Pressure Preparation and Catalytic Activity of MOF-Derived Cu Nanoparticles&#8221;<\/b><br \/>\nIchiro Yamane, Kota Sato, Ryoichi Otomo, Takashi Yanase, Akira Miura, Taro Nagahama, Yuichi Kamiya and Toshihiro Shimada<br \/>\n<i>Nanomaterials<\/i>, 2021,<b>11<\/b>(4),1040; <strong>DOI:<a href=\"https:\/\/doi.org\/10.3390\/nano11041040\" rel=\"noopener\" target=\"_blank\">10.3390\/nano11041040<\/a><\/strong>\n<\/li>\n<li>\n<b>&#8220;Ceria-supported palladium as a highly active and selective catalyst for oxidative decomposition of ammonium ion in water with ozone\u201d<\/b><br \/>\nPhilip Anggo Krisbiantoro, Tomokazu Togawa, Koki Kato, Jieqiong Zhang, Ryoichi Otomo, Yuichi Kamiya<br \/><i>Catal.
