Abstract:Chromium nitride nanocrystalline were successfully synthesized at 550 oC through a new solid-state reaction route. The synthesis was carried out in an autoclave by using Cr and NaNH2 as the reactants. Characterized by XRD, TEM and SAED, the composition and morphology of the products were confirmed. This work contributes an effective and facile method for preparing the refractory metal nitride. | |||

Abstract:Effect of heat treatment on the activity of nickel phthalocyanine (NiPc) catalysts for oxygen reduction reaction (ORR) was studied in both acid and alkaline electrolytes. The catalytic activity was found to depend strongly on the electrolyte and heat treatment temperature. High ORR activity was demonstrated on 40%NiPc/C electrode in 0.1M KOH solution, and the heat-treatment of 800oC is optimal for the catalyst synthesized. Further using rotating disk electrode (RDE) measurements and Koutechy-Levich analysis, the overall electron transfer number in the catalyzed ORR on 40%NiPc/C was found to be 2.8, suggesting the catalyzed ORR proceeds via both the 2e- transfer reduction and the 3e- transfer reduction. | |||

Abstract:A fluorescence resonance energy transfer (FRET) based fluorescent 1,1’-bisnaphthal (BINOL) boronic acid chemosensor was designed in which BINOL moiety acts as energy donor and a second fluorophore of anthracene as the energy acceptor. The new sensor demonstrated the characteristic enhancement/diminishment response profile and emits at red-shifted wavelength (420 nm) than a previously reported BINOL-boronic acid sensor (emits at 358 nm ) | |||

Abstract:A novel Zn(II) complex, [Zn(Cl4phen)2(H2O)2](NO3)2•CH3CH2OH(1) (Cl4phen= 3,4,7,8-tetrachloro-1,10-phenanthroline), has been synthesized, and characterized by elemental analysis, 1H-NMR, FT-IR, thermogravimetric analysis and photoluminescence studies and its single crystalline determined by single crystal X-ray diffraction. It reveals that the single crystalline crystallizes in the monoclinic system, with space group P2(1)/c, a=10.061(2) Å, b=18.924(4) Å, c=18.189(4) Å, β=100.94(3)°, and Z=4. Complex (1) consists of cationic species [Zn(Cl4phen)2(H2O)2]2+, NO3- and CH3CH2OH. The zinc atom displays a distorted cis-N4O2 octahedral geometry. Via extended Zn-O-H…O-N-O…H-O-Zn bridge, every mononuclear unit is linked with other ones to form one-dimensional (1D) infinite chain of hydrogen bond system. Three-dimensional (3D) polymeric network arrangement is built via weak C-H…O and π-stacking interactions between Cl4phen moieties. Spectroscopic properties suggest that complex (1) has a solvent-dependency effect. | |||
