To date, the effect of oxidation state on activity remains controversial in whether higher or lower oxidation states benefit the enhancement of catalytic activity. Herein, we discover a volcanic relationship between oxidation state and hydrogen evolution reaction activity based on Os single-atom catalysts...
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...
Molecular hydrogen is an abundant energy carrier, mostly produced from natural gas by steam reforming,24,25 and it is also the fuel of choice for a sustainable future, particularly if produced from water and biomass. There are many investigations on the electrochemistry of hydrogen26,27 and its...
Hydrogen spillover has been coined to denote an important effect involved in heterogeneous catalysis1,2, in which atomic H species produced from H2dissociative adsorption on a catalytic site spontaneously migrate to a different type of site that cannot readily dissociate H2molecules under the same con...
The volatile organic compounds (VOC) are emitted as pollutants into the atmosphere from many natural and artificial sources. The oxidation of VOC by the at... L Sandhiya,P Kolandaivel,K Senthilkumar - 《Structural Chemistry》 被引量: 17发表: 2012年 Low‐Temperature Sintering of Uranium Dioxi...
South Australia has shown that not to be the case, with a mix of wind, solar, natural gas and interconnectors, glued together with a 100 MW Tesla battery, but has experienced something of a difficult journey to reach that point; the state was an early adopter, so presumably others will ...
Because of the low costs currently mainly natural gas is used for the above reforming processes; the processes might be also used to convert biogas, in the case of supercritical water reforming even wet biomass, into hydrogen. 2.2.2.2 Partial oxidation POX is the substoichiometric oxidation of pr...
A Natural Solution To Man-made Problems Another route is replacing petrol and diesel in cars with cleaner fuels such as methane and hydrogen. Finding new materials to store these gases safely ... F Mearns - 《Organic & Biomolecular Chemistry》 被引量: 0发表: 2009年 Water soluble synthetic di...
Another significant research lineage related to solar energy harvesting utilized natural machinery built into plants. Employing simple green plant cells such as photosynthetic algae15, researchers developed means to activate natural hydrogenases in the cytosol for hydrogen evolution16,17. Because hydrogenase...
In order to better understand the relevance of this model of cardiac oxidative stress to natural cardiac pathologies, we measured the relative degree of oxidation of the glutathione pool in the hearts of rats expressing DAAO. The highly abundant tripeptide glutathione (“GSH”) provides much of th...
