An unexpected approach to fabricate the Se/C hierarchical nanobelts via the Se-directed calcination of selenized glucose

Selenium-doped carbon materials: synthesis and applications for sustainable technologies

“…Many interesting examples of biochars serving as high-performance adsorbents for metal removal and recycling can be found in the literature. 79,123 Zhu et al presented a rich family of Se-doped biochars prepared from various carbohydrates via their selenization followed by pyrolysis. 79,123 The Se-doped chars were utilized to remove Pb from wastewater from a lead battery factory.…”

Selective preconcentration separation of Hg(ii) and Cd(ii) from water, fish muscles, and cucumber samples using recycled aluminum adsorbents

“…To overcome these limitations, preliminary separation and preconcentration processes become urgent steps that are needed before the direct measurement, especially in the presence of low concentrations of target ions. To date, numerous methods including solid phase extraction (SPE), [13][14][15][16][17][18] cloud point extraction (CPE), 19 otation, 20 and liquidliquid extraction (LLE) 21 have been designed for the separation and/or preconcentration of the heavy metal ions. Due to the high extraction efficiency, and rapid phase separation, the SPE has been widely applied as the preconcentration technique.…”

Kilogram-Scale Production of Selenized Glucose

“…Selenium-doped carbon (Se/C) as a heterogeneous catalyst has been successfully applied in the epoxidation of β -ionone and Beckmann rearrangement of ethyl 2-(2-aminothiazole-4-yl)-2-hydroxyiminoacetate to produce the related spice and pharmaceutical intermediates. , Very recently, it has even been found to be an efficient bactericide for Xanthomonas campestris pv. campestris ( Xcc ) to prevent the cabbage black rot disease and was utilized as a heavy metal scavenger for industrial wastewater treatment . Selenized glucose is the precursor for the preparation of Se/C. − …”
