“…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.…”

“…On the other hand, the advances in nanotechnology and in the techniques of preparation of nanostructures significantly increase the effective area of the electrode and facilitate the processes of charge transfer, which improves the limits of detection of biomolecules . Although the selectivity due to the presence of the enzyme is very difficult to replace, the developments in the non‐enzymatic glucose sensors (NEGs) field have allowed important progress at this area , .…”

In this study, the electrodeposition of nickel hydroxide nanoparticles onto a screen‐printed electrode (Ni(OH)2/SPE) is described. Ni(OH)2/SPE is proposed as an alternative non‐enzymatic glucose sensor based on Electrochemical Impedance Spectroscopy (EIS) measurements.The SPEs were modified by the cathodic electrodeposition of nickel, from a solution containing 0.010 M Ni(NO3)2 and 1 M NH4Cl, at −1.3 V for 60 seconds. The SEM images show a uniform distribution of nickel spherical nanoparticles, with 60 nm average particle size. However, such morphology is not observed when the electrodeposition occurs in the absence of NH4Cl. The electrochemical properties of the sensor were carefully evaluated by Cyclic Voltammetry. Ni(OH)2/SPE shows a remarkable electrocatalytic behavior towards the oxidation of glucose in 0.1 M KOH. EIS measurements were carried out for Ni(OH)2/SPE and a single‐frequency impedance method is proposed as transduction principle for glucose determination. The analysis of each parameter of complex impedance was performed. The best linear response was obtained for the module of impedance (|Z|) in the range of 0–2 mM of glucose at 0.1 Hz (R2=0.992) with a slope of 0.137 KΩ−1⋅mM−1 of glucose. Finally, Ni(OH)2/SPE was utilized for quantification of glucose in blood samples.

Pristine metal‐organic frameworks (MOFs) and their composites, which have received wide attention in recent years, especially in the field of electrocatalysis, are emerging as distinctive electrocatalysts for the oxygen reduction reaction (ORR), hydrogen evolution reaction (HER), carbon dioxide reduction reaction (CO2RR), oxygen evolution reaction (OER), and many other electrochemical redox reactions. In this review, the attention is focused on the development of monometallic‐MOFs and multimetallic‐MOFs (including bimetallic‐MOFs and trimetallic‐MOFs) for electrocatalysis in recent years, including their design, catalytic performance and strategies for activity improvement. Finally, major challenges in utilizing pristine MOFs and their composites for electrocatalysis are highlighted.
