“…The CN (g-C 3 N 4 ) synthesized through the pyrolysis of urea is a fluffy lightweight powder with a paleyellow color, while the CTS (Cu 3 SnS 4 ) synthesized through the coprecipitation process is a black precipitate with a slight For the synthesis of the CTS/CN composites, a known amount of CN was added to a precursor solution used for the synthesis of CTS (SnCl 4 and Cu(ac) 2 dissolved in distilled water) and sonicated for 30 min, followed by precipitation with the addition of the precipitating agent. A series of CTS/CN composites with varying contents of CTS (20,30,40,50, and 60% wt/wt). were prepared and labeled -20CTS/CN, 30CTS/ CN, 40CTS/CN, 50CTS/CN, and 60CTS/CN.…”
