1. Hydrogen gas is fed to one electrode that is coated with a noble metal such as platinum or a platinum alloy effective in catalyzing the dissociation of hydrogen molecules into atoms and the ionization of these atoms into hydrogen ions (H+, or protons). This catalytic “hydrogen electrode...
This latter class had four known members: ICl, CNCl, BF , and SiF4What is interesting is that at least two of these, BF3 and SiF4, are considered today to be good examples ofLewisacids. 后一类有四个已知成员:ICl、CNCl、BF 和 SiF4 有趣的是,其中至少有两个 BF3 和 SiF4 如今被认为是路...

1b). The layered structure endows LSP zeolites with extensive open framework tri-coordinated Al sites (oFTAl) as strong Lewis acid sites, resulting in superior activity to activate the inert C–H bonds of PE to supply hydrogen internally. Time-resolved analysis, solid-state nuclear magnetic ...
Hydrogen production from the air was realized through our DAE module. As shown in the sandwich structure in Fig.2a, b, this module consists of a water harvesting unit in the middle and electrodes on both sides paired with gas collectors. The module is integrated with a power supply, for ex...
The extinction strain rate ranges from 30 s−1 to 5200 s−1 at inlet temperatures of 773 K–973 K and fuel concentrations of 10 mol%–50 mol%, indicating that the hydrothermal flame stability is much worse than gas-phase combustion. The unity Lewis number assumption underpredicts the ...
Hydrogen and oxygen atoms combine to form water (H2O), while hydrogen and carbon atoms combine to form hydrocarbons found in natural gas, coal and petroleum.3 For hydrogen to be used as an energy source, the element must be isolated—extracted from water or hydrocarbons. There are several ...
In addition, neighbor fluorine atoms compete with each other that result in worse Lewis-base potential. If a compound is partially fluorinated, the hydrogen atoms via forming weak CH···O bonds can interact with CO2 molecules, which creates a form of stabilizing force on the interaction ...
