“…Research findings demonstrate that enzymatic catalysts exhibit high activity and excellent selectivity, but the unstable operating environment and fragile stability greatly hinder their practical applications [5,6]. To overcome these drawbacks, non-enzymatic catalysts (such as precious metal nanoparticles or alloys [7][8][9][10], composite materials [11,12], polymers [13,14] and transition metal oxides [15][16][17][18]) as enzyme mimics show higher performance than enzymatic ones. Among these non-enzymatic catalysts, transition metal oxides play important roles due to their high intrinsic catalytic performances, low cost, and environmental friendliness.…”

“…The CV was conducted to investigate the electrochemical performance of the composite Co 3 O 4 @NPC 1600 from −0.1 V to 0.7 (vs. Ag/AgCl) V in 0.1 M KOH. A weak oxidation peak was observed at 0.32 V (vs. Ag/AgCl) in the first cycle (Figure a), which can be attributed to the reaction :

true Co_{3} normalO_{4} + OH^{-} + normalH_{2} normalO \to 3 CoOOH + normale^{-}

“…Hence, the candidates such as noble metals (Pt, Au,[8] Pd[9]), alloys[10] and metal oxides (CuO , CU 2 O , TiO 2 [13], CoO , NiO , MnO 2 [16], Co 3 O 4 [15]) have been proposed for their stable and efficient properties to the GOR. Among them, Co 3 O 4 have attracted much attention for its remarkable electrochemical and catalytic properties on glucose oxidation ,. However, the poor conductivity of Co 3 O 4 restrict its performance on the GBFCs and biosensors.…”

A novel hierarchically nanoporous carbon (NPC) derived from Al‐based porous coordination polymer is prepared by two‐step carbonization method for immobilization of the Co3O4 in the application of the nonenzymatic biofuel cells and biosensors. The structure and morphology are characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), high‐resolution transmission electron microscopy (HRTEM), and X‐ray diffraction (XRD). Brunauer‐Emmett‐Teller (BET) is to characterize the porous nature of the NPC, and X‐ray photoelectron spectroscopy (XPS) is to characterize the composition of Co3O4@nanoporous carbon (Co3O4@NPC). Without collapse in the high carbonization temperature (above 1600 °C), the NPC maintains the nanoporous structure and high specific surface area of 1551.2 m2 g−1. In addition, the NPC is composited with Co3O4 by hydrothermal method to form the Co3O4@NPC. When tested as the nonenzymatic electrocatalyst for glucose oxidation reaction (GOR), the Co3O4@NPC exhibits higher response to glucose, in which the current shifts up by 64 %, than pure Co3O4 in 0.1 M KOH. The limit of detection is 0.005 mM (S/N=3) and response time is within 3 s. The detection range can be divided into two sections of 0.02–1.4 mM and 1.4–10.7 mM with the sensitivity of 249.1 μA mM−1 cm−2 and 66.6 μA mM−1 cm−2, respectively. A glucose fuel cell is constructed with the Co3O4@NPC as the anode and Pt/C catalyst as the cathode. The open‐circuit potential of the nonenzymatic glucose/O2 fuel cell was 0.68 V, with a maximum power density of 0.52 mW cm−2 at 0.27 V. This work may contribute to exploring other nanoporous carbons for application in glucose fuel cells and biosensors.

“…Recently, the emergence of metal–organic frameworks (MOFs) has provided a straightforward route to prepare highly dispersed nano‐sized electrocatalysts within porous carbons . In particular, the characteristics of zeolitic imidazolate frameworks (ZIFs) have inspired the development of new electrocatalysts as porous carbon composites embedded with transition metal compounds with heteroatom‐doping can be derived through a one‐step process.…”

A convenient, controllable method to fabricate an electrode is necessary to achieve the practical application of a hydrogen evolution reaction (HER) catalyst. In this work, an electrodeposition–ZIF conversion–sulfuration strategy is developed to produce a CoS2@N/S‐codoped porous carbon (CoS2@NSC/CFP) to drive the HER efficiently. CoS2@NSC/CFP was prepared by the electrodeposition of Co(OH)2 on a carbon fiber paper followed by conversion into ZIF‐67 and subsequent sulfuration with sulfur. The loading of electroactive components can be controlled easily in the range of 0.7–10.0 mg cm−2 by varying electrodeposition time from 5 min to 2 h. The resulting material can be employed directly as a working electrode for the HER and it shows an excellent catalytic activity and stability with an overpotential of 95 mV at 10 mA cm−2 and 158 mV to reach 100 mA cm−2 in an acidic medium. The high efficiency is related intimately to the high dispersion of ultra‐small CoS2 nanoparticles, heteroatom‐codoping, and the 3 D porous network configuration of the carbon fiber paper.
