“…For instance, Zhang's group concluded that the degradation of Rhodamine B under ultraviolet light irradiation was much accelerated over the 3D hierarchical BiOCl compared to their common counterparts [12]. Song et al found that the hierarchical BiOCl flowers assembled from thin nanoplates exhibited the enhanced photocatalytic activity for the decomposition of methyl orange under modeling sunlight [13]. Wang et al further reported that the porous BiOCl microflowers composed of ultrathin nanosheets possessed higher photocatalytic performance via a photosensitization pathway under visible light illumination [14].…”

“…36 The absorption peak at 535 cm À1 is indexed to the Bi-O stretching vibration in a tetragonal phase BiOCl crystal. 37 Further observation nds that the stepwise increase in intensity and slight shi of the band at 1200-1600 cm À1 and 808 cm À1 from hybrid BiOCl-CNs-1% to BiOCl-CNs-5%, possibly owning to an intense interaction between CNs and BiOCl phases with the increase of CNs content. This intense interaction is essential to transfer and separate charge carriers and accordingly enhance the photocatalytic activity of hybrids.…”

Construction of exfoliated g-C3N4 nanosheets–BiOCl hybrids with enhanced photocatalytic performance

Exfoliated g-C 3 N 4 nanosheets (CNs) were composited with bismuth oxychloride (BiOCl) to fabricate a series of hybrids via a facile chemical deposition-precipitation method in this investigation. The as-synthesized BiOCl-CNs hybrids were then fully characterized by a collection of analytical techniques. It was obviously observed that CNs were in intimate contact with hierarchical BiOCl flowerlike units to form heterojunction structures, which facilitates transfer and efficient separation of photoinduced electronhole pairs, thus greatly increasing catalytic activity upon visible light irradiation. Together with other merits such as enlarged specific surface area, favorable optical properties, and suitable energy-band structures, these robust BiOCl-CNs hybrids showed significantly enhanced photocatalytic performance towards Rhodamine B (RhB) dye removal. Under identical conditions, the apparent photocatalytic reaction rate of the best hybrid BiOCl-CNs-3% was about 2.1 and 26.6 times as high as those of BiOCl and CNs alone, respectively. A possible photocatalytic mechanism was also proposed by means of active species trapping measurements, revealing that superoxide radicals (cO 2 À ) played a crucial role during the catalytic process.

“…Song et al reported that BiOCl could lose chlorine and decompose into BiO and Cl 2 by heat treatment in N 2 flow. [15] Moreover, metal oxychloride/metal systems could also show a large Gibbs free energy change yielding a high electromotoric force (EMF) during the chloride ion transfer. For instance, the VOCl 2 /Li electrochemical couple possesses a high EMF of 2.78 V and a theoretical energy density of 984.2 Wh g À1 (Supporting Information, Figure S1).…”

Metal Oxychlorides as Cathode Materials for Chloride Ion Batteries

et al. 2013

View full text Add to dashboard Cite

A key challenge of chloride ion batteries is to develop cathode materials that are stable in the electrolytes. Metal oxychlorides are presented as such a cathode material. The electrochemical performance and the reaction mechanisms of the BiOCl and FeOCl cathode were investigated. Both cathodes showed reversible reactions, including a major conversion reaction and a minor intercalation process, by chloride ion transfer during cycling.
