在绿色能源转型的大背景下，氢能作为核心能源载体的重要性日益凸显。电解水制氢技术是实现“双碳”目标的关键路径之一。然而，高效析氢反应（HER）催化剂的开发长期受限于贵金属铂（Pt）的高成本和低丰度。钌（Ru）虽然具备与Pt相近的氢吸附能力且成本更低，但 ...

The software ReciPro makes various crystallographic calculations, visualizes a crystal structure, simulates a diffraction pattern and high-resolution TEM image, indexes diffraction spots, plots ...

氨作为一种重要的能源载体，其大规模应用面临的关键挑战在于分解反应中对昂贵且稀缺的贵金属钌（Ru）催化剂的依赖。这一限制不仅阻碍了氨作为能源载体的广泛应用，也增加了氢气生产的成本。因此，研究者们开始探索使用地球上丰富的元素制造的合金催化剂，尤其是双金属 ...

DURING the last visit of the late Dr. E. W. Washburn to Toronto in the latter part of 1933, in an address on the properties of heavy water, he announced that water vapour, when condensed at very ...

负载型贵金属簇催化剂通常在苛刻的条件下操作，涉及在还原和氧化气氛之间切换，这会导致催化剂结构不可逆地转变，从而导致永久失活。鉴于此，福州大学鲍晓军教授、朱海波教授发现各种Pt前体会自发分散在Ge-MFI沸石中，这与奥斯特瓦尔德熟化现象相反，从而产生用 ...

聚烯烃是全球产量最大的塑料产品，但是难以自然降解，造成了严重的环境问题。塑料垃圾中蕴含着丰富的碳氢资源，若将其转化为液体燃料，部分替代石油路线燃料，可减少对石油的开采。利用金属/氧化物双功能催化剂，可以在较温和条件下将废塑料转化为高值燃料、蜡和润滑油 ...
