Dynamic structural evolution of iron catalysts involving ...

Feb 04, 2022 Nanoscale metallic iron and iron carbide are easily oxidized with exposure to air, which brings uncertainty to the characterizations. The phase transformation and surface reconstruction of iron carbide occur during CO hydrogenation [Fischer-Tropsch synthesis (FTS)] (15, 16), which possibly also occur during CO 2 hydrogenation, given that the two reactions …

Feb 19, 2022 Wang et al. used the SDBD reactor to eliminate the P123 copolymer from SBA-15. The FT-IR spectra of as-synthesis SBA-15, SBA-15-C, and SBA-15-DBD are illustrated in Figure 10(b). Normally, the aliphatic stretching and bending vibrations are observed at wavenumbers between 2950 and 2840 cm –1 and 1500–1350 cm –1, respectively.

Artificial cells: from basic science to applications - PMC

It has been suggested that life might have originated in a hydrothermal environment [42,43], in which the spatial temperature gradient provided conditions for primitive genetic molecules (DNA, RNA) to self-replicate and proliferate in a PCR-like fashion [41,44,45]. Protein biosynthesis can also be carried out in liposomes.

Pyrolysis: A Sustainable Way to Generate Energy from Waste ...

Oct 15, 2016 Conversely, pyrolysis under vacuum gives little char and gives more liquid fractions. For pyrolysis under pressure, moisture in the vapour phase can systematically upsurge the production of carbon. Because, in that case water is acting as catalyst by reducing the activation energy for pyrolysis reactions [ 46 ].The gas flow rate significantly ...

Renewable energy-driven methanol synthesis from CO 2 and green hydrogen is a viable and key process in both the “methanol economy” and “liquid sunshine” visions. Recently, In 2 O 3-based catalysts have shown great promise in overcoming the disadvantages of traditional Cu-based catalysts.Here, we report a successful case of theory-guided rational design of a much higher …

Serpentinite - Wikipedia

Serpentinite - Wikipedia

Serpentinite is a rock composed of one or more serpentine group minerals, the name originating from the similarity of the texture of the rock to that of the skin of a snake. Minerals in this group, which are rich in magnesium and water, light to dark green, greasy looking and slippery feeling, are formed by serpentinization, a hydration and metamorphic transformation of ultramafic rock …

Superheated water - Wikipedia

Superheated water - Wikipedia

Superheated water is liquid water under pressure at temperatures between the usual boiling point, 100 C (212 F) and the critical temperature, 374 C (705 F).It is also known as subcritical water or pressurized hot water . Superheated water is stable because of overpressure that raises the boiling point, or by heating it in a sealed vessel with a headspace, where the liquid …
