A photocatalyst is a substance that can help cause a light-catalyzed reaction, such as chlorophyll capturing sunlight to turn water and carbon dioxide into oxygen and glucose in photosynthesis. Ordinary photocatalysts can decompose organic pollutants in sewage under ultraviolet light, which, however, on...
This carbon–sulfur bond formation reaction is highly efficient and practical since it works under metal-free, neutral, aqueous media and at room temperature in which the products even can be obtained by simple filtration without the need for organic extraction or column chromatography. Water is ...
The dependence of the rate constant for the uncatalyzed reaction between CO2 and water has a nonlinear dependence on the atom fraction of deuterium in the solvent. We conclude that the observed isotope effect must arise from more than one hydrogen in the transition state. 展开 ...
the fuel carried by Chang’E-5 lander is methylhydrazine and dinitrogen tetroxide. The plume eruption during the landing process will produce water and carbon dioxide, and the chemical reaction formula can be written as 4CH3NHNH2+5N2O4 = 9N2+4CO2+12H2O. The water produced by the plume...
magnesium and phosphorus. Halogenated hydrocarbons, commonly called halons, take the form of liquefiedgasor vaporizing liquids at room temperature; theyinhibitthe flamechain reaction. Steam is used to control fire in confined areas, whileinert gasis employed to extinguish gas, dust, and vapour fires...
The geothermal water contains high contents of trace components such as Fe, As and Sb, and thus are not suitable for drinking. The δ13C value of HCO3− is between −3.31‰ and −7.79‰, and the calculated δ13C value of CO2 involved in water-rock reaction is between −9.50‰ ...
In the carbon based hydrogen production, Water gas shift reaction is the intermediate step used for hydrogen enrichment and CO reduction in the synthesis gas. This paper makes a critical review of the developments in the modeling approaches of the reaction for use in designing and simulating the ...

J.G. performed synthesis, characterization and catalytic reaction experiments. Q.H. performed some catalytic reaction experiments. Z.D. and M.D. performed the DFT calculations. S.D.K. and R.S. measured the XAFS spectra. C.T. measured the HAADF-STEM images of Mn-NG. J.G., C.L. and...
nanoconfinement strategy was applied to encapsulate short-lived RS at nanoscale to boost the utilization efficiency of the RS in Fenton-like reactions. The nanoconfined catalyst was fabricated by assembling Co3O4nanoparticles in carbon nanotube nanochannels to achieve exceptional reaction rate and excellent...
