Abstract
A new Ni metal organic framework based on 2,2′-Biphenyldicarboxylic, 4,4′- bipyridine as linker is prepared by hydrothermal reaction and directly used as an electrode material for supercapacitor and the detection of sarcosine. [Ni3(BIPY)3(BPDA)2(HCOO)2(H2O)2]n (Ni-1; BIPY = 4,4′-bipyridine; BPDA = 2,2′-Biphenyldicarboxylate) displays the specific capacitance of the Ni-1 are 667 F/gat 1 A/g and retention is 82% of initial capacitance at 1 A/g. The excellent electrochemical property is ascribed to the intrinsic nature of Ni-1. Furthermore, the sarcosine sensing performance of the Ni-1 electrode is evaluated in 0.1 M of NaOH solution and the electrode showed a wider range of linear response 1 × 10−4 M to 1 × 10−3 M. Thus, the results show that the Ni-1 is a potential candidate for not only sensing of sarcosine but also supercapacitor application.

In coordination mode of Ni(1), N1, and N2 come from two bipyridine molecules, O1 is from biphenyl dicarboxylic acid molecules, O6 and O6d are from two formic acid molecules, and O5 is from water molecules
Summary
Potential threatening energy crisis and environmental pollution force scientists and engineers to develop clean and very efficient energy storage technologies to overcome these issues. Supercapacitors are among such novel energy solutions because they demonstrate high-power density, long-termstability, and fast charging and discharging when needed [1–6]. MOFs have been demonstrated to be useful for electrochemical energy storage and are considered as the most promising electrode material candidatefor SCs due to their high surface area, tunable pore size, controllable pore structure, and special structures with potentialpseudo-capacitive redox centers [7–10]. Diagnosis of PCA significantly reduced the mortality rate [8].
