On the basis of the unprecedented one-dimensional {Cu 2 (tetrazole)(SO 4 )-(OH)} n cluster, a novel two-dimensional layered copper(II) organic framework, {[Cu 2 (TTB)-, is constructed from 1-(tetrazo-5-yl)-4-(triazo-1-yl) benzene (HTTB) and CuSO 4 under hydrothermal conditions. Photocatalytic experiments revealed that 1 is an outstanding semiconducting material (E g = 2.21 eV) for the degradation of methyl blue under UV light irradiation. Besides, electrocatalytic research showed that the 1@NF electrode shows better oxygen evolution reaction (OER) performance than RuO 2 @NF, reaching a current density of 10 mA•cm −2 when the overpotential of OER is 377 mV in 1.0 M KOH electrolyte and the Tafel slope of 1@NF is 15.6 mV•dec −1 . Meanwhile, the overpotential of the hydrogen evolution reaction (HER) is 242 mV at a current density of 10 mA•cm −2 , with the Tafel slope being 23.1 mV•dec −1 , also suggesting the HER performance of 1@NF is better than that of Pt/C@NF. The durability test showed the electrocatalytic activity of 1@NF was maintained at 90% after 12 h. Photocatalytic and electrocatalytic properties show that 1 is an excellent candidate as a multifunctional material to solve environmental pollution and energy shortages.
