Liquid hydrogenation reaction is one of the essential reactions in fine chemical and pharmaceutical industry. The low H₂ concentration on catalyst surface is a major kinetic limitation for these reactions. In this study, it is proposed and demonstrated for the first time that creating superaerophilic surface is an efficient way to increase H₂ concentration on catalyst surface, and thus significantly enhancing the hydrogenation reaction rate in aqueous solution. As a proof of concept, Pd nanoparticles loaded on graphene aerogel (GA) with different degrees of aerophilic/aerophobic surfaces (denoted as Pd/GA, Pd/NGA‐2, and Pd/NGA‐4, respectively) are prepared and tested for hydrogenation reactions. Pd/GA with superaerophilic property (H₂ bursting time within 92 ms) shows the highest catalytic reaction rate in all tested reactions under the same conditions, including hydrogenation of styrene, nitro, and aldehyde compounds. The hydrogenation of aldehyde compounds with Pd/GA at ambient H₂ pressure is even comparable to those of Pd/NGA‐4 and commercial Pd/C with superaerophobic property at 6 bar H₂ pressure. Such strategy is expected to find wide applications in many other catalytic reactions involving gases, and may lead to revolutionary change in fine chemical industry.

超级好氧材料是令人惊讶的催化剂：在常压H2下可润湿性导致优异的加氢活性

液体加氢反应是精细化工和制药工业中必不可少的反应之一。催化剂表面上低的H ₂浓度是这些反应的主要动力学限制。在这项研究中，首次提出并证明产生超需氧表面是增加催化剂表面H ₂浓度，从而显着提高水溶液中氢化反应速率的有效方法。作为概念验证，制备了负载在石墨烯气凝胶（GA）上的具有不同程度的需氧/需氧表面（分别表示为Pd / GA，Pd / NGA-2和Pd / NGA-4）的Pd纳米颗粒并进行了测试氢化反应。具有超好氧性能的Pd / GA（H ₂在92毫秒内的爆裂时间）显示了在相同条件下所有测试的反应中最高的催化反应速率，包括苯乙烯，硝基和醛化合物的加氢反应。在环境H ₂压力下用Pd / GA进行醛化合物的氢化反应甚至可以与在6 bar H ₂压力下具有超好氧性能的Pd / NGA-4和市售Pd / C进行氢化。预期这种策略将在涉及气体的许多其他催化反应中找到广泛的应用，并可能导致精细化学工业的革命性变化。
