“…The main drawback is the low performance stability due to the degradation of the electrodes due to the high temperatures. In some recent studies, single cells have reached lifetimes of 11,000 [35] and 23,000 [36] hrs. Instead, data on small stacks refer to 4000 operation hrs.…”

“…H2O2, a product existing in biochemical processes in living organisms, plays a key role in normal cellular function and proliferation. [40][41][42][43][44] For example, it regulates the DNA damage and produces intracellular thermogenesis, both of which are the basic process for normal life. [45][46][47] Detection of H2O2 in a quantitative manner of high sensitivity and low detection limit in a reasonably broad range is of high importance, and it is our interest to employ it here as a model reaction to demonstrate the utilization of the sensor device built up from our maskless photo-deposited porous PILs.…”

Porous poly(ionic liquid)s (PILs) recently have been actively serving as a multifunctional, interdisciplinary materials platform in quite a few research areas, including separation, catalysis, actuator, sensor, and energy storage, just to name a few. In this context, the capability to photo-pattern PIL microstructures in a porous state on a substrate is still missing but is a crucial step for their real industrial usage. Here, we developed a method for in situ rapid patterning of porous PIL microstructures via a maskless photolithography approach coupled with a simple electrostatic complexation treatment. This breakthrough enables designs of miniaturized sensors. As exemplified in this work, upon loading Pt nanoparticles into porous PIL microstructures, the hybrid sensor showed outstanding performance, bearing both a high sensitivity and a wide detection range.

“…Thus, metals nanoparticles doped Gr have been applied in order to increase the electrocatalytic activity of H 2 O 2 sensors, such as Pt, Au, ZnO, CoO, MnO 2 . Among of them, platinum nanoparticles (PdNPs) were used for designing different H 2 O 2 sensors due to its interesting properties, such as high conductivity and electrocatalytic activity that enhance the electron transfer process of H 2 O 2 as well as reduce the reduction overpotential . In addition, PdNPs composite Gr have been applied in order to improve and increase nanocomposite sensors activity for high sensitive H 2 O 2 sensors .…”

Nonenzymatic sensors based on a metals nanocomposite with high sensitivity, selectivity, and stability has been received considerable interest. In this study, a novel electrochemical nanocomposite sensor based on palladium nanoclusters (PdNCs) decorated electrochemically activated graphene (EAGr) was established for highly sensitive nonenzymatic H2O2 sensor. The PdNCs/EAGr nanocomposite was fabricated via an electrochemical activation of Gr by the potential cycling in the range of +0.6 to −1.8 V, followed by the electrodeposition of PdNCs at −0.4 V applied potential. The homogeneous dispersion of PdNCs/EAGr nanocomposite were characterized by scanning electron microscopy (SEM), X‐ray photoelectron spectroscopy (XPS), cyclic voltammetry (CV), and linear sweep voltammetry (LSV). The PdNCs/EAGr nanocomposite electrode showed higher electrocatalytic activity towards the reduction of H2O2 in pH 7.0 of 0.1 M PBS by significantly enhancing the reduction peak current and reduced the reduction overpotential as well as eliminated other interfering species responses. The PdNCs/EAGr electrode displayed a wide linear range for H2O2 reduction from 1.0 to 1100 μM with limit of detection 0.02±0.01 μM. The higher sensitivity and selectivity as well as long‐time stability and excellent reproducibility obtained, indicating the proposed sensor is an effective H2O2 based sensor. In addition, the analytical application of the nancomposite sensor was successfully examined for the determination of H2O2 in the real sample of human urine indicating that the appreciable practicality of the nonenzymatic sensor for the determination of H2O2 in physiological fluids.
