New materials for photocatalytic degradation of Indigo Carmine—Synthesis, characterization and catalytic experiments of nanometric tin dioxide-based composites

Ozonation of the food dye Brilliant Blue in aqueous medium: monitoring and characterization of products by direct infusion electrospray ionization coupled to high‐resolution mass spectrometry

“…A complex mixture is usually obtained and the mineralization rates, as measured by the reduction of the total organic carbon content, are generally low . The identification of such by‐products is usually complicated and cumbersome, requiring the application of sophisticated instrumental methods . Hence, to achieve this task, electrospray ionization high‐resolution mass spectrometry (ESI–HRMS) has become the method of choice.…”

Synthesis, characterization, and comparative gas sensing properties of tin dioxide nanoflowers and porous nanospheres

“…In particular, tin dioxide (SnO 2 ) is one of the most important intrinsic n-type semiconductor with a wide band gap (E g = 3.6 eV at 300 K) [4], and outreaching technological applications is various fields such as gas sensors [5,6], photocatalysis [7,8], solar cell [9,10], and battery [11,12].…”

Identification of degradation products of indigoids by tandem mass spectrometry

“…For the separation of complicated mixture of degradation products, prior to MS detection, usually, liquid chromatography was recommended . Gas chromatography was also used, but with additional derivatization step . More information concerning molecular structures of the formed species offered tandem mass spectrometry .…”

“…[17,19,21] Gas chromatography was also used, but with additional derivatization step. [16,17,20,22] More information concerning molecular structures of the formed species offered tandem mass spectrometry. [23] The observed main neutral losses were H 2 O, CO, CO 2 and HCN, and they allowed to identify functional groups present in degradation products.…”
