Molecularly Tuned Size Selectivity in Thermal Processing of Gold Nanoparticles

Abstract: This report demonstrates for the first time that the size selectivity of nanoparticles in the thermal processing solution of pre-synthesized nanoparticles can be achieved by molecularly tuning the chain length and concentration of alkanethiols.

“…One important approach involves core-shell type synthesis [19]. The core and shell are from different matters in close interaction, including inorganic/organic and inorganic/inorganic combinations [20,21]. The synthesis of metal nanoparticles in the presence of organic capping agents to form encapsulated metal nanoparticles has demonstrated promises for preparing nanocatalysts [20,21].…”

The synthesis of metal nanoparticles in the presence of organic capping agents to form encapsulated metal nanoparticles has demonstrated promises for preparing nanocatalysts [20,21]. The coupling of molecularly-mediated synthesis of nanoparticles and post-synthesis thermochemical processing under controlled temperatures and atmospheres have demonstrated effectiveness in the preparation of nanocatalysts.…”

“…A síntese desse tipo de nanopartículas metálicas tira proveito de diversos atributos, incluindo a monodispersão e estabilidade em termos de propriedades como tamanho, forma, composição, de fase e propriedades de superfície, em comparação com as abordagens tradicionais 50 . Na síntese de materiais do tipo coreshell, o núcleo e casca são de materiais diferentes com interação próxima, incluindo combinações inorgânicos/orgânicos e inorgânicos/inorgânicos 51,52 . A síntese de nanopartículas de metal na presença de agentes de proteção orgânicos para formar nanopartículas de metal encapsuladas demonstrou ser promissora para a preparação de nanocatalisadores 51,52 .…”
