Degradation by Hydrogen Peroxide of Metal

2015/3/23After e.g. 100 h of operation, the electric charge passed per mg of catalyst is 100 3600 0.125 = 4.5 10 4 C mg −1, equivalent to 0.466 mol of electrons per mg of catalyst. If the % H 2 O 2 produced as a by-product of the ORR is 5% (5 mol H 2 O 2 produced for 100 mol of reacted O 2 ), then it ensues that 5 mol H 2 O 2 are produced for 390 mol of electrons.

Titanium

Titanium is a chemical element with the symbol Ti and atomic number 22. Its atomic weight is 47.867 measured in daltons.It is a lustrous transition metal with a silver color, low density, and high strength. Titanium is resistant to corrosion in sea water, aqua regia, and chlorine.

Natural gas to synthesis gas

2011/5/1Encapsulating carbon is a thin film of a few atom layers of graphite, which covers the nickel particles and leads to deactivation of the catalyst. Pyrolytic carbon refers to the thermal cracking of hydrocarbons and is formed from the exposure of higher hydrocarbons to high temperatures, typically above 600 C ( Rostrup-Nielsen, 1984 ).

It's Elemental

The Element Platinum - Basic Physical and Historical Information Used by the pre-Columbian Indians of South America, platinum wasn't noticed by western scientists until 1735. Platinum can occur free in nature and is sometimes found in deposits of gold-bearing sands, primarily those found in the Ural mountains, Columbia and the western United States.

Thorium

This element is now named radon, the only one of the rare radioelements to be discovered in nature as a daughter of thorium rather than uranium. [102] After accounting for the contribution of radon, Rutherford, now working with the British physicist Frederick Soddy, showed how thorium decayed at a fixed rate over time into a series of other elements in work dating from 1900 to 1903.

Multiple Doped Carbon Nitrides with Accelerated

The interaction of water molecule with catalysts is crucial to photocatalysis, but the surface property manipulation still remains a great challenge. In this study, we report an in situ multiple heteroelement (sodium, oxygen, and iodide) doping strategy based on a molten salt-assisted route to prepare a green-colored carbon nitride (GCN). The as-prepared GCN yields 25.5 times higher H2

Carbon nanotube supported catalyst

Background Catalyst supports and supported catalysts Catalysts are widely used in various chemical reactions.The activity, stability, selectivity, and regeneration ability are the most important properties to be considered in catalyst design. The catalyst supports can improve specific properties such as mechanical strength, distribution, stability, catalytical reactivity and selectivity of

From double‐atom catalysts to single‐cluster catalysts: A

The charge density distribution showed that Fe atoms have a higher charge density than Co atoms, indicating a reducing nature of the Fe atom and an oxidizing nature of the Co atom. DFT studies showed that CO preferentially adsorbs at the Co sites and O 2 adsorbs at the Fe sites following the Langmuir‐Hinshelwood (L‐H) mechanism.
