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 ...

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 ...

Fitting of full X-ray diffraction patterns is an effective method for quantifying abundances during X-ray diffraction (XRD) analyses. The method is based on the principal that the observed diffraction ...
