Even though the reaction by-product from the fuel cell is water, the membranes are most often kept hydrated by humidifying the inlet hydrogen and/or air gas streams. The proton conductivity measured in Siemens per centimeter (S cm−1) for a 3M ionomer with an equivalent weight (EW) of ...
Oxygen evolution reaction(OER) plays an important role in both water splitting process and greenhouse gas (CO2) reduction. With the increasing concerns inenvironmental issuesand clean energy sources, a highly efficient OER reaction is desired nowadays. However, the sluggish kinetics has been limiting ...
The commonly accepted mechanism for hydrogen sensing is the chemisorbed oxygen mechanism, in which the hydrogen gas undergoes a redox reaction with the chemisorbed oxygen on the surface of the material, and the electrons transfer between the oxygen chemisorbed on the surface and conduction/valence ...
A formula is obtained for the rate coefficient for the production of a particle with a specific energy in an elastic collision with the atoms of a thermal gas. Accurate calculations are carried out of the energy transfer in elastic collisions of oxygen and hydrogen atoms. The fractions of hydro...
PROBLEM TO BE SOLVED: To provide a one-pack oxygen-generating agent comprising a mixture of a hydrogen peroxide adduct with a hydrogen peroxide adduct-resistant catalase preparation hardly suffering from deterioration in enzymatic activities even in the copresence of the hydrogen peroxide adduct.收藏...
The maximum yields of oxygen atoms, estimated at different levels in a long-tube reactor by gas-phase "titration" with NO 2 , were equal for the reactions of active nitrogen with NO and O 2 . In this reactor, the maximum oxygen-atom production from the oxygen reaction, determined by the...
摘要: The Transfer of Oxygen Atoms in Oxidation—Reduction Reactions. IV. The Reaction of Hydrogen Peroxide with Sulfite and Thiosulfate, and of Oxygen, Manganese Dioxide and of Permanganate with Sulfite - ResearchGateDOI: 10.1021/ja01122a027 被引量: 72 ...
Oxygen-fluorine acid, with the chemical formula HOF and CAS registry number 82419-35-0, is a compound known for its strong oxidizing properties. This colorless gas is highly reactive and can decompose explosively under certain conditions. It is primarily used as a fluorinating agent in organic ...
Therefore, the photosynthesis carried out by these photoautotrophic organisms is associated with and supported by the most ancient and fundamental OFM on Earth, the photosystem complex. Oxygen molecules are generated during the photosynthetic process as a waste product through a water-splitting reaction ...
The second is to quickly pour a volume of hydrogen peroxide (H2O2) into the operating basin. When the level of power is increased, the value of KLa is determined by analysis of the increase in DO concentration as it approaches the new equilibrium value. When the hydrogen peroxide method is...
