Double bond conversion can be experimentally determined by infrared spectroscopy (IR), Fourier-transform infrared spectroscopy (FTIR), or mid-infrared spectroscopy [8,9]. Upon IR irradiation the atoms of a molecule are energized and vibrate in patterns like stretching, bending, and rotation. Differen...
The energy required for the excitation of the carbon atom can be easily overcome by an external perturbation, for example, in the presence of other atoms like hydrogen or oxygen. To form chemical bonds, these atomic orbitals are mixed to establish degenerate sp3, sp2, or sp hybrid orbitals. ...
Mechanistic studies show that alkenes insert into the Ir-H bond, followed by a rather rare C(sp3)-C(sp3 ) reductive elimination and double C-H activation to eventually lead to the carbene dihydride complex. Alkynes also insert into the Ir-H bond to give vinyls, followed by a rare C(...
Oxygen-containing carbons are promising supports and metal-free catalysts for many reactions. However, distinguishing the role of various oxygen functional groups and quantifying and tuning each functionality is still difficult. Here we investigate the r
and the formation of an oxygen–oxygen bond. As a first trial to promote oxygen evolution from water by BCN, we choose RuO2and IrO3, and Ni-Co layered double hydroxides (Ni-Co LDHs) as cocatalysts31. Results revealed that Ni-Co LDHs is the best cocatalyst (Supplementary Fig. 15), pote...
(Peer-review conclusions of an IRPTC expert consultation (May 1985))Adsorption: The CS2 /carbon disulfide/ adsorption employs activated coal which adsorbs it from the mixture with hydrogen sulfide in the absence of free oxygen. An industrial installation with the capacity to regenerate as much as...

Electrocatalytic CO2 reduction reaction (CO2RR) is an attractive way to simultaneously convert CO2 into value-added fuels and chemicals as well as to store
This bond type also deforms the graphite surface structure which allows for the storage of excess lithium [339]. However, the presence of a negative charge (oxygen functionalities) and also the disordered lattice structure can hinder the formation of the semi-ionic C–F bond and LiF formation ...
The present invention provides a method for forming a substantially carbon- and oxygen-free conductive layer, wherein the layer can contain a metal and/or a metalloid material. According to the presen
