主 题：tin oxide nanocrystals facile synthesis photocatalytic activity
摘 要：Tin oxide nanociystals with diameters smaller than 10 nm were synthesized using Na2SnO3 and CO2 as reactants and cetyltrimethylammonium bromide（CTAB） as stabilizer under mild *** a mild acidic gas,CO2 is favorable for the accurate adjustment of pH value of Na2SnO3 *** salt is stable,cheap and easy in *** effects of Na2SnO3concentration,CTAB concentration,aging temperature,and aging time on the nanociystals were *** was found that,with the increasing Na2SnO3 concentration,aging temperature and aging time,SnO2 nanociystals size *** formation of SnO2nanociystals can be interpreted by electrostatic-interaction ***2 nanociystals show high photocatalytic activities in the degradation of Rhodamine B *** catalytic activity of small nanocrystals is higher than that of large ones.
