LU Sumin, MA Youguang, SHEN Shuhua, ZHU Chunying

Frontiers of Chemical Science and Engineering 2008, Volume 2, Issue 4,   Pages 368-372 doi: 10.1007/s11705-008-0067-3

Abstract: The influence of the properties of solid particles in slurry on the absorption of CO in the slurry wasThe absorption experiments were carried out in three different slurries consisting of water, cyclohexaneHowever, it was observed that the active alumina and silica gel particles could enhance the absorptionThese phenomena indicate that the solid particles, which could enhance the gaseous CO absorption rate, should possess two properties simultaneously, i.e. they rejected the solvent and had higher adsorption

Nanostructured gold films exhibiting almost complete absorption of light at visible wavelengths

Hanbin Zheng, Christine Picard, Serge Ravaine

Frontiers of Chemical Science and Engineering 2018, Volume 12, Issue 2,   Pages 247-251 doi: 10.1007/s11705-018-1710-2

Abstract: Nanostructured metal surfaces have been known to exhibit properties that deviate from that of the bulk material. By simply modifying the texture of a metal surface, various unique optical properties can be observed. In this paper, we present a simple two step electrochemical process combining electrodeposition and anodization to generate black gold surfaces. This process is simple, versatile and up-scalable for the production of large surfaces. The black gold films have remarkable optical behavior as they absorb more than 93% of incident light over the entire visible spectrum and also exhibit no specular reflectance. A careful analysis by scanning electron microscopy reveals that these unique optical properties are due to their randomly rough surface, as they consist in a forest of dendritic microstructures with a nanoscale roughness. This new type of black films can be fabricated to a large variety of substrates, turning them to super absorbers with potential applications in photovoltaic solar cells or highly sensitive detectors and so on.

Vanadium(IV) solvent extraction enhancement in high acidity using di-(2-ethylhexyl)phosphoric acid with

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 1,   Pages 56-67 doi: 10.1007/s11705-022-2185-8

Abstract: Separation of vanadium from black shale leaching solution at low pH is very meaningful, which can effectively avoid the generation of alkali neutralization slag and the resulting vanadium loss. In this study, coordination mechanism of vanadium in acid leaching solution at low pH was investigated with the intervention of chloride ions. Under the conditions of pH 0.8, di-(2-ethylhexyl)phosphoric acid concentration of 20%, phase ratio of 1:2, and extraction time of 8 min, the vanadium extraction could reach 80.00%. The Fourier transform infrared and electrospray ionization results reveal that, despite the fact that the chloride ion in the leachate could significantly promote vanadium extraction, the chloride ion does not enter the organic phase, indicating an intriguing phenomenon. Among Cl−–V, SO42−–V, and H2O–V, the V–Cl bond is longer and the potential difference between coordinate ions and vanadium is smaller. Therefore, VO2+ gets easily desorbed with chloride ions and enter the organic phase. At the same time, the hydrogen ions of di-(2-ethylhexyl)phosphoric acid also enter the water phase more easily, which reduces the pH required for the extraction reaction.
