摘要:Ternary and quaternary Chalcopyrite CuInxGa1-xSySe2-y (CIGS, where 0≰x and y≰1) nanoparticles were synthesized from molecular single source precursors (SSPs) by a one-pot reaction in a high boiling solvent using salt(s) (i.e. NaCl as by-product) as heat transfer agent via conventional convective heating method. The nanoparticles sizes were 1.8 nm to 5.2 nm as reaction temperatures were varied from 150° C. to 190° C. with very high-yield. Tunable nanoparticle size is achieved through manipulation of reaction temperature, reaction time, and precursor concentrations. In addition, the method developed in this study was scalable to achieve ultra-large quantities production of tetragonal and quaternary Chalcopyrite CIGS nanoparticles.

摘要:A process comprising reacting, in a reactor having a fixed bed containing a solid catalyst which contains a zeolite, hydrogen sulfide and an oxirane in the presence of the solid catalyst to yield a reaction product with contains a mercapto-alcohol. A reactor system includes the reactor, an oxirane feed stream, a hydrogen sulfide feed stream, a fixed bed containing the solid catalyst placed inside the reactor, and an effluent stream containing the reaction product. The hydrogen sulfide and the oxirane are present in a mole ratio in a range of about 5:1 to 50:1.
