“…CPs can be used for the formation of sensor-structures that are selective toward selected analyte, because they can be used for the immobilization of various biological materials, ranging from enzymes [ 10 , 11 ], antigens [ 12 ], antibodies receptors and for the formation of molecularly imprinted polymers [ 13 , 14 ]. CPs are characterized by a rather good electrical conductivity [ 15 ] and capacitance [ 16 , 17 , 18 ], adhesion to electrically conducting surfaces and mechanical stability [ 19 , 20 ], charge transfer ability, which can be successfully exploited in charge transfer from redox proteins towards metal- or carbon-based conductors [ 21 ]. Therefore, various electrochemically and optically active conducting polymers are used in the design of various sensors and biosensors as signal transducing systems.…”

Recent challenges in biomedical diagnostics show that the development of rapid affinity sensors is very important issue. Therefore, in this review we are aiming to outline the most important directions of affinity sensors where polymer-based semiconducting materials are applied. Progress in formation and development of such materials is overviewed and discussed. Some applicability aspects of conducting polymers in the design of affinity sensors are presented. The main attention is focused on bioanalytical application of conducting polymers such as polypyrrole, polyaniline, polythiophene and poly(3,4-ethylenedioxythiophene) ortho-phenylenediamine. In addition, some other polymers and inorganic materials that are suitable for molecular imprinting technology are also overviewed. Polymerization techniques, which are the most suitable for the development of composite structures suitable for affinity sensors are presented. Analytical signal transduction methods applied in affinity sensors based on polymer-based semiconducting materials are discussed. In this review the most attention is focused on the development and application of molecularly imprinted polymer-based structures, which can replace antibodies, receptors, and many others expensive affinity reagents. The applicability of electrochromic polymers in affinity sensor design is envisaged. Sufficient biocompatibility of some conducting polymers enables to apply them as “stealth coatings” in the future implantable affinity-sensors. Some new perspectives and trends in analytical application of polymer-based semiconducting materials are highlighted.

“…Furthermore, the peak‐to‐peak separations of the NiCoCH, NiCH, and CoCH electrodes are enlarged when the sweep rates increase due to the polarization effect. Nonetheless, two pairs of redox waves of the NiCoCH are clearly preserved at high rates, indicating rapid and reversible charge storage kinetics 14,23,24 …”

“…Recently, bimetallic transition metal compounds and their composites have been investigated as potential electrode materials for a high energy density of HSC, owing to their abundant redox‐active sites and multiple valence states from various metallic species 23,24 . Furthermore, the metal carbonate hydroxide‐based materials possess additional benefits, because the hydrophilic nature of carbonate (CO 3 2− ) anion increases the wetting nature of the electrode surface and decreases the polarization of the electrode during a redox reaction 14,25 .…”

Interconnected network‐like single crystalline bimetallic carbonate hydroxide nanowires for high performance hybrid supercapacitors

Summary The one‐dimensional (1D) nanoarchitectures are attractive toward energy storage electrode materials because of their large available surface area, a short and efficient pathway for ion/electron transport, structural stability, and highly exposed electrochemically active sites. Herein, we develop the bimetallic single crystalline nickel cobalt carbonate hydroxide (NiCoCO3(OH)2) nanowires for the high capacitance electrode of hybrid supercapacitor (HSC). This unique NiCoCO3(OH)2 nanowire electrode reveals a maximum specific capacitance value of 1948 F g−1 at 1 A g−1 with a high rate capacitance of 859 F g−1 even at 30 A g−1, which is a considerably higher value than the monometallic nickel carbonate hydroxide (1159 F g−1) and cobalt carbonate hydroxide (859 F g−1), respectively. These results are attributed to the presence of abundant redox‐active sites of multivalent Ni and Co and an easy charge transport pathway of NiCoCO3(OH)2 nanowire. The as‐designed HSC full cells, configuring NiCoCO3(OH)2 nanowire and activated carbon as a positive and native electrodes, respectively, deliver energy and power densities of 56.56 W h kg−1 and 44.81 kW kg−1. Moreover, the HSC cells exhibit prominent cycling stability of 91.4% for 12 000 charge‐discharge cycles in 6 M KOH aqueous electrolyte.

“…[28,29] Furthermore, the basic carbonates can increase the hydrophilicity of the material due to the intercalation of CO 3 2À , which is more conducive to the penetration of the electrolyte solution into the interior of the material, thereby forming a simple pathway for the rapid transport of electrolyte ions. [30][31][32] There have been many reports on the preparation of transition metal carbonates with different morphology as electrode materials. P. Vishnu Vardhan et al prepared micron MnCO 3 balls via chemical precipitation and applied them to a supercapacitor whose capacitance was 194 F g À 1 at a specific current of 0.5 A g À 1 .…”

Herein, we developed a novel microwave-assisted hydrothermal synthetic method for urchin-like bimetallic manganesecobalt carbonate composites. Compared with the traditional process, the microwave-assisted hydrothermal process is not only environmentally friendly, but also more convenient. The electrode of supercapacitors prepared at 120°C for 10 min exhibited the best electrochemical performance, which could deliver a high capacitance of 839.58 F g À 1 at 1 mA cm À 2 and remain 82.12 % of its initial capacitance even after 8,000 successive charge-discharge cycles at a high current density of 6 mA cm À 2 . We have found the possibility of using a microwave-assisted hydrothermal process to synthesize the urchinlike bimetallic manganese-cobalt carbonate composites, which is of great importance for the application of bimetallic manganese-cobalt carbonate composites in the supercapacitor field.
