In this study, one-dimensional conductive MOFs Ni3(HHTP)2 with nanorod-like morphology on the surface of a woven fabric were synthesized using an in-situ growth method. The effects of substrate concentration, scan rate, and current density on electrode properties were investigated using a three-electrode system. The results showed that the material demonstrated excellent area capacitance and maintained a high percentage of specific capacitance even at increased current density. The study also revealed that the material had the lowest internal transfer resistance and the best conductivity.
In this work, one-dimensional (1D) conductive MOFs Ni3(HHTP)2 with nanorod-like morphology on the surface of a woven fabric was synthesized by an in-situ growth method. Based on a three-electrode system, the effects of substrate concentration, scan rate and current density on electrode properties were investigated, respectively. The results showed that Ni3(HHTP)2 @ woven fabric-3 (NHWF-3) demonstrated the largest area capacitance at 5 mV s-1 and reached up to 360 mu F cm-2 at 20 mu A cm-2. Most importantly, the material still maintained 58.3% (210 mu F cm-2) of the initially areal specific capacitance when the current density was increased 5 times to 100 mu A cm-2. According to the electrochemical impedance spectroscopy (EIS) curve, NHWF-3 has the smallest semicircle radius in the high-frequency region, indicating that it has the lowest internal transfer resistance and the best conductivity. Thus, this study provides a good example for the simple preparation and practical ap-plications of conductive MOFs composites.
