in alcohol oxidations due to their excellent catalytic performance. In this work, we synthesized a series of core@shell PtAuAg@PtAg hollow nanodendrites (HNDs) with different compositions by a simple seed-mediated method. The PtAuAg@PtAg HNDs with a hollow core and dendritic shell exhibit excellent catalytic performance for ethylene glycol oxidation reaction (EGOR) and methanoloxidation reaction (MOR)
具有核@壳结构的铂基催化剂由于其优异的催化性能而广泛用于醇氧化。在这项工作中,我们通过简单的种子介导方法合成了一系列具有不同组成的核@壳 PtAuAg@PtAg 空心纳米枝晶(HND)。具有空心和树枝状壳的 PtAuAg@PtAg HNDs 对乙二醇氧化反应 (EGOR) 和甲醇氧化反应 (MOR) 表现出优异的催化性能。其中,Pt 38 Au 29 Ag 33 HNDs对EGOR和MOR的质量活性最高(12364.0 mA mg Pt –1 /3278.0 mA mg Pt –1),分别是商业Pt/C的4.2倍和5.3倍(2941.0 mA 毫克铂–1 /617.6 mA mg Pt –1 ),分别。更重要的是,经过连续循环伏安法测试后,Pt 38 Au 29 Ag 33 HND的保留质量活度分别为 3913.8 mA mg Pt –1和 348.3 mA mg Pt –1,这也远高于商业

The reaction of glyoxylate with carbon dioxide to produce lactate is promoted when zinc sulfide is irradiated by ultravioletlight. These results, representing a model for the action of colloidal mineral semiconductors on early Earth, complete a consecutive series that culminates in entry-point molecules of the reductive tricarboxylic acid cycle.

The OH radical is the most important oxidant in both the tropospheric gas and aqueous phase. Its main sink processes in clouds appear to be reactions with organics but due to the lack of appropriate kinetic data current cloud chemistry models consider only reactions with C1 and C2 compounds. Therefore, in this study temperature dependent rateconstants for the reactions of the OH radical with organic
