【摘要】 该文研究了在硫酸铜硫酸溶液中，用Ｐｄ做催化剂，由Ｈ２和Ｏ２常压合成Ｈ２Ｏ２的反应。反应分２步完成，第１步通氢气还原，第２步通空气氧化。结果表明，在常温、常压下，Ｈ２Ｏ２的生成量与还原时间、氧化时间以及Ｐｄ、Ｃｕ含量等因素有关。在Ｐｄ含量为２０～２５μｍｏｌ／Ｌ，硫酸铜溶液中Ｃｕ２＋浓度为１０ｍｍｏｌ／Ｌ时，Ｈ２Ｏ２的生成量最大，可直接得到３ｍｍｏｌ／Ｌ的Ｈ２Ｏ２溶液。更多还原

【Abstract】 At atmospheric pressure, the synthesis of hydrogen peroxide in copper sulfate and sulfuric acid solution, with palladium as catalyst, has been studied. The reaction has two steps, the reduction step with hydrogen gas flowing throughout the solution and the oxidation step with air flowing throughout the solution. The results show that, under the atmospheric temperature and pressure, the quantity of produced hydrogen peroxide is related to the reduction time, oxidation time, palladium content and copper ion content and so on. When Pd content is 20～25 μmol/L and the concentration of Cu 2+ ion of copper sulfate solution is 10mmol/L, the maximum quantity of hydrogen peroxide can be produced, and the 3 mmol/L solution of hydrogen peroxide can be obtained directly.更多还原
