Structural analysis shows that the NiCP has a corrugated layer structure due to the bridging effect of terephthalate anion and the ligand L. The composite electrode supported by the NiCP-CPE exhibits good hydrogen evolution activity, with a I i SB 10 sb overpotential of -521 mV, and a Tafel slope of 123 mA dec SP -1 sp . In combination with the auxiliary bridging ligand terephthalate anions and nickel cations a new 2D Ni(II) coordination polymer (NiCP) has been prepared. [Extracted from the article]
