Tunability by alkali metal cations of photoinduced charge separation in azacrown functionalized graphene.
نویسندگان
چکیده
A modified graphene oxide containing aza-9-crown-3 ether units covalently anchored has been prepared; aqueous suspensions of this material in the presence of Li(+), Na(+) and K(+) cations exhibit enhanced electrochemical response, enhanced photoinduced charge separation and longer lifetimes, facts that can be attributed to stabilization of electrons on graphene oxide by the nearby alkali metal cation-azacrown complexes.

In this research, graphene oxide (GO) was functionalized by tannic acid to produce GO-TA and fabricate a novel functionalized graphene oxide/ polyacrylonitrile (PAN) nanofibrous as an adsorbent in order to remove two hazardous heavy metals from aqueous solutions. The results showed that the composite adsorbent can properly adsorb Pb2+ and Cd2+ metal cations, due to having the numerous potential...

A series of adamantane functionalized diaza-lariat ethers 1–6 have been prepared and alkali metal picrate extraction profiles determined. The ability of aza-crown ethers 1–6 to extract the alkali metal picrates was compared with that of diaza-18-crown-6 (7) and N,N '-dibenzodiaza-18-crown-6 (8). Na and K transport across bulk liquid membrane was also measured. The results of alkali metal cation...
