The Front Cover illustrates the dehydrogenation reaction of propane on the surface of gallium oxide. In this context, NiGa nanoalloys generate hydrogen shields that protect the oxide surface from coke deposition. In their comprehensive Research Article, R. Naumann d'Alnoncourt et al. demonstrate how the addition of nickel to gallium oxide influences coke formation during propane dehydrogenation. Through X-ray diffraction analysis and electron microscopy, they reveal the formation of NiGa nanoparticles distributed on the catalysts surface. Interestingly, these nanoalloys do not directly participate in propane conversion. However, in situ thermogravimetric experiments show a significant reduction in the coking rate, when gallium oxide is decorated with a small amount of NiGa. The findings suggest that the activation of hydrogen by NiGa plays a crucial role in preventing coke formation. More information can be found in the Research Article by R. Naumann d'Alnoncourt et al.

封面：通过在负载型氧化镓中添加镍来控制丙烷脱氢过程中焦炭的形成 (ChemCatChem 8/2024)

封面说明了丙烷在氧化镓表面上的脱氢反应。在这种情况下，NiGa 纳米合金会产生氢屏蔽层，保护氧化物表面免受焦炭沉积。 R. Naumann d'Alnoncourt 等人在他们的综合研究文章中。演示在氧化镓中添加镍如何影响丙烷脱氢过程中焦炭的形成。通过X射线衍射分析和电子显微镜，他们揭示了分布在催化剂表面的NiGa纳米粒子的形成。有趣的是，这些纳米合金并不直接参与丙烷转化。然而，原位热重实验表明，当氧化镓用少量 NiGa 修饰时，焦化率显着降低。研究结果表明，NiGa 对氢的活化在防止焦炭形成方面起着至关重要的作用。更多信息请参阅 R.
