在十六烷基三甲基溴化铵（CTAB）胶束溶液中，酮的光化学反应引发了金纳米棒的光化学合成。光激发的金离子和银溴化簇（（AgBr）n）在酮的情况下没有产生NR。光辐射的初始产物可能是酮基自由基，然后引发反应形成NR。NR在黑暗中形成，如果反应溶液用UV光照射几分钟，从而表明光化学产物催化NR-形成。
Photochemical synthesis of gold nanorods (NRs) in a micellar solution of hexadecyltrimethylammonium bromide (CTAB) was triggered by photoreactions of ketones. Photoexcitation of gold ions and silver bromide clusters ((AgBr)n) in the absence of ketones did not produce NRs. The initial products of the photoirradiation were probably ketyl radicals, which then initiated reactions to form NRs. NRs formed in darkness, if the reaction solutions were irradiated by UV light for a few minutes, thus indicating that the photochemical products catalyzed NR-formation.
