Investigation of metal xanthates as latent curing catalysts for epoxy resin via formation of in-situ metal sulfides

Preparation and characterization of colloidal copper xanthate nanoparticles

“…At the same time, the behavior of the samples between 250 1C and 900 1C, although somewhat different (ESI †), was characteristic of Cu 2 S 33 but not covellite (CuS). 34 This disagrees with the previous works 17,32 that reported the formation of CuS and is worthy of further investigation.…”

Colloidal and Immobilized Nanoparticles of Lead Xanthates

“…Heavy metal salts of xantic acid (the O-ester of carbonodithionic acid) M(SSCOR) n , where M is a metal cation, R is an alkyl group, and n = 1, 2, or 3, are utilized in the production of cellulose, rubber, pesticides, lubricants, and so forth, for example. 1−4 Xanthates of lead and transition metals are prospective precursors to nanoparticles and films of metal sulfides, allowing a low-temperature, between 100 and 200 °C, in situ preparation of nanoparticulate sulfides within the polymer matrix for photovoltaics, sensors, and so forth. 5−14 Xanthates have been proposed as capping ligands in the synthesis of metal nanoparticles and self-assembled monolayers alternative to thiols.…”

Water-insoluble xanthates of lead, copper, and some other metals likely emerge as colloidal or surface species in the reaction between the xanthate collector and aqueous cations in the flotation slurries, and their interaction with mineral surfaces is important for understanding the flotation mechanisms and performance. − The ultrafine xanthate entities are also possible carriers of lead and heavy metals in wastewaters and natural surface waters, along with metal sulfide colloids − or as their precursors.…”

Stability Improvement of Perovskite Solar Cells by Adding Sb‐Xanthate to Precursor Solution

“…It has been reported that metal xanthates give metal sulfide by low-temperature baking and the decomposition temperature depends on the substituent structure. [19][20][21][22][23][24][25][26] Figure 6 shows thermogravimetry analysis (TGA) and differential thermal analysis (DTA) results on the Sb-xanthate decomposition. The weight loss started at 120 C and end-thermic behavior assigned to decomposition and gas evolution was observed.…”
