Ag2S/Ag Heterostructure: A Promising Electrocatalyst for the Hydrogen Evolution Reaction

Abstract: Different metal chalcogenides, being a potential candidate for hydrogen evolution catalysts, have attracted enormous attention in the field of water splitting. In the present study, AgS/Ag is revealed as an efficient catalyst for hydrogen evolution. When a sacrificial template of the CuS nanostructure is used, AgS/Ag heterostructures are synthesized following a simple wet-chemical technique. Two different routes, wet chemical and hydrothermal, are followed to modulate the morphology of the CuS templates from f… Show more

“…Other than MoS 2 there are four new peaks at 2θ value of 38.2, 44.4, 64.5, 77.5 which corresponds to the crystal planes of (111), (200), (220) and (311) of Ag nanostructure. The XRD pattern matches well with the cubic structure of Ag (JCPDS No, 04–0783) …”

“…To date, various types of noble‐metal‐based heterostructures have been reported (Figure g–j), but the most active ones are still based on Pt or Pd, which possess the optimal binding energy to hydrogen . The concept here is to make the full use of noble metals and taking advantage of the synergistic effect between the counterparts.…”

“…Средний размер D частиц (более точно -средний размер областей когерентного рассеяния (ОКР)) в тон-кодисперсных порошках сульфида серебра оценивали методом рентгеновской дифракции по уширению β(2θ) дифракционных отражений, используя зависимость при-веденного уширения отражений β * (2θ) = [β(2θ) cos θ]/λ от вектора рассеяния s = (2 sin θ)/λ [9][10][11]. Дифракцион-ные отражения описывали функцией псевдо-Фойгта.…”

“…Их действие основано на восстановлении катионов Ag + сульфида серебра до атомов металлического серебра Ag, превращении акантита α-Ag 2 S в аргентит β-Ag 2 S и возникнове-нии проводящего канала из серебра Ag и аргентита β-Ag 2 S [6-8]. Гибридные гетеронаноструктуры Ag 2 S/Ag обнаруживают повышенную эффективность в фотоката-лизе [9].…”
