| In recent years, photocatalytic oxidation of organic pollutants under visible lightillumination has become an important scientific subject in the field of photocatalysis.Due to its intimate relationship with the environmental issues and energy saving.Ag/AgX (X=Cl, Br, I) based surface plasmonic photocatalysts have currently beendemonstrated that could display excellent and stable photocatalytic performance forthe photodegradation of organic pollutants under sunlight or visible–light irradiations,and great progresses have been achieved about this kind of new typevisible–light–driven surface plasmonic photocatalysts. Meanwhile, nanocatalystswith well-defined facets are currently of great interest for modern heterogeneouscatalysis. Unlike the conventional facet-dependent catalytic investigations, focusingon an identification of highly reactive facets. Beyond the traditional facet-dependentphotocatalytic studies, this work represents a considerable advance in thedevelopment of facet-dependent yet substrate-sensitive photocatalysts.In this work, we have investigated nanofabricaon of Ag/AgCl by means ofsurfactant-assisted assembly (SAS) protocol.The dissertation includes thefollowing three parts:1. Ag/AgCl nanospheres and nanosheets enriched AgCl {111} facets weresuccessfully prepared2. Compared to Ag/AgCl nanospheres, sheetlike counterparts with display superiorcatalytic performance towards methyl orange photodegradation. Unexpectedly,the so-called highly reactive AgCl {111} exhibits inferior catalytic activitytowards the photodegradation of4-chlorophenol or phenol.3. The related mechanism of interesting photocatalytic behaviors was proposedaccording to the experimental facts. |
