Abstract
In this paper, a 3D cobalt coordination polymer [Co2(Medpq)2•(H2BTC)3•OH]n (H3BTC = 1,3,5-Benzenetricarboxylic acid, Medpq = 2-methyldipyrido[3,2-f:2′,3′-h]quinoxaline) was synthesized by hydrothermal process. The structures of the coordination polymer were determined by single-crystal X-ray diffraction; it indicated that coordination polymer crystallizes in the orthorhombic space group Pnna, with a = 16.7889(18) Å, b = 21.702(2) Å, c = 9.8224(10) Å, V = 3578.8(6) Å3. The coordination polymer was characterized by IR and elemental analysis. At the same time, the promoter catalytic properties of the coordination polymer were studied under the visible light; the photocatalytic rate of hydrogen production of the composite photocatalyst has three times higher than that of the pure g-C3N4 and more than five times as much as [Co2(Medpq)2•(H2BTC)3•OH]n, indicating that the coordination polymer had excellent separation ability of photogenerated carriers for the commercialization of photocatalytic hydrogen production technology.
