in which they are antiparallel.At normal temperaturesthe gas is 25% parahydrogen. In theliquid it is 99.8% parahydrogen. Themain source of hydrogen is steamreforming of natural gas. It can alsobe made by the Bosch process (seehaber process) and by electrolysis ofwater. The main use is in...
physical, and electronic properties. However, the synthesis of ultrathin metastable phase two-dimensional metallic nanomaterials is highly challenging, mainly due to the anisotropic nature of metallic materials and their thermodynamically unstable ground-state. Here, we report free-standing RhMo nanosheets...

Knowledge of the location, the local environment, and the oxidation state of hydrogen in a solid material is an essential starting point to understanding its impact on material properties. Yet, hydrogen is particularly difficult to detect by many conventional methods. In the following, we highlight...

It was subjected to a variety of steady state and cycling conditions and a detailed performance and optimization analysis was performed with a range of hydrogen/natural gas mixtures. The optimized system was then installed at the Canadian Centre for Housing Technologies (CCHT)...
(natural gas), and air over a platinum catalyst; it is called the Andrussow process. The second process, which involves the reaction of ammonia and methane, is called the Blaus€aure–Methan–Ammoniak (BMA) process; it was developed by Degussa in Germany. Hydrogen cyanide is also obtained...
7 demonstrates that the oxidation state of Ge for SGO is +425. The high-resolution Sn 3d XPS spectra of SO in Fig. 1c shows the binding energy of Sn 3d5/2 and Sn 3d3/2 at 486.6 eV and 495.0 eV, suggesting the Sn species are Sn4+ ions in SO26,27,28. Compared with ...
While Ru owns superior catalytic activity toward hydrogen oxidation reaction and cost advantages, the catalyst deactivation under high anodic potential range severely limits its potential to replace the Pt benchmark catalyst. Unveiling the deactivation m
