Photocatalytic CO 2 reduction represents a promising strategy for clean, cost-effective, and environmentally friendly conversion of CO 2 into hydrocarbon fuels by utilizing solar energy. This strategy combines the reductive half-reaction of CO 2 conversion with an oxidative half reaction, e.g., H ...
Oxygen Reduction Reaction is defined as the crucial process that determines the energy output of fuel cells. It involves theoretical debates in the scientific community due to the lack of direct evidence for specific reaction intermediates, such as HO2∗, OH∗, and O∗, during the reaction...
This type of complete artificial photosynthesis system is difficult to build and optimize; therefore, researchers typically study the reductive half-reaction and the oxidative half-reaction separately. To study the two half-reactions, researchers use a sacrificial electron donor to provide electrons for ...
Considering the significant growth of recent studies on 2D materials and MOFs for use in the CO2 reduction reaction, this review summarizes the results obtained for 2D materials and MOFs in CO2 reduction research, including the photocatalytic and electrocatalytic CO2 reduction processes. 2. Fundamenta...
The equilibrium constant and rate constant for the disproportionation reaction 2Ru(I) half arrow right over half Ru(II) + Ru(0) were 2.0 and 6.3 x 10(4) M-1 s-1, respectively. The diffusion coefficient of the Ru(II) complex was only about 0.45 times that of the Ru(0) complex. ...
Table 1 Catalyst flow reactor results for CO2 + C3H8 reaction Full size table Exchanging Ni in the Fe3Ni catalyst with precious metal Pt (Fe3Pt) roughly reduces the activity by half, decreases the selectivity toward C3H6 to 32%, and is unstable compared to Fe3Ni (Supplementary Fig. ...
It is shown that the redoX potential indicates only the potential capacity of the system, and is not an unambiguous criterion of the degree of oxidation of UO 2 ; the effective reaction rate is limited by the reaction mechanism.A study is made of the way in which the degree of oxidation ...
Cu/CuxO and Pt nanoparticles supported on multi-walled carbon nanotubes (MWCNTs) were studied as electrocatalysts for the reduction of nitrobenzene in a half-cell set-up. This reaction not only produces valuable chemicals, but has the potential to generate electricity if applied in a fuel cell ...
(PGM) electrocatalysts. Fe-N-C family has been received extensive attention because of its low cost, long service life and high oxygen reduction reaction activity in recent years. In order to further enhance the ORR activity, the synthesis method, morphology regulation and catalytic mechanism of ...
