Gold nanoparticles (AuNPs) were synthesized using a facile solvothermal method with alginate sodium as both reductant and stabilizer. Formation of AuNPs was confirmed by UV-vis spectroscopic analysis. The synthesized AuNPs showed a localized surface plasmon resonance at approximately 520–560 nm. The AuNPs were characterized using transmission electron microscopy, X-ray diffraction and dynamic light scattering. Transmission electron microscopy revealed that the AuNPs were mostly nanometer-sized spherical particles. Powder X-ray diffraction analysis proved the formation of face-centered cubic structure of Au. Catalytic reduction of 4-nitrophenol was monitored via spectrophotometry using AuNPs as catalyst, and further a non-enzymatic sensor was fabricated. The results demonstrated that AuNPs presented excellent catalytic activity and provided a sensitive response to H2O2 detection.

Electrochemical detection of hydrogen peroxide has achieved rapid development, due to the wide presence in industrial production, everyday life, bioprocess and green energy chemistry, etc. Many three‐dimensional structures have emerged as state‐of‐the‐art electrocatalysts due to their fascinating structures and electrochemical properties. This review summarizes free‐standing three‐dimensional electrocatalysts based on metal, metal oxide, carbon & silicon, and unconventional materials for detection of hydrogen peroxide with low limit of detection, wide range and fast response. The work also highlights their applications in near neutral conditions, especially their ability for single cell detection and mapping in biological environment. Further exploration into these materials together with devices design will facilitate the development of next‐generation detection technologies toward in situ and real‐time detection and contribute to wearable/portable smart detection electronics.

“…To impart high sensitivity and some chemical specificity not available at the unmodified electrode, the electrode surfaces were widely modified with various materials. Recently, some groups have attempted to detect trace amounts of compounds using MOF bulk crystals with electrocatalytic activity for modification on the electrode surfaces because of their naked active sites, high surface areas, specific adsorption affinity and various pore sizes . In addition to the direct modification of single component MOFs on the electrode surfaces, the introduction of other highly conductive and mechanically durable materials in MOFs has been developed to overcome the disadvantages such as poor stability in water, low electronic conductivity, and unsatisfactory electrocatalytic ability.…”

frameworks (MOFs), synthesized by assembling metal nods with organic linkers, are highly ordered crystalline materials. MOFs have attracted much attention for applications in electrochemical sensors, because of their unique chemical and physical properties including ultrahigh porosity, large surface area, tunable structure, and high thermal and chemical stability. In particular, redox and catalytic active sites introduced by use of active metal ions and/or ligands endow MOFs with the functions required in electrochemical sensing. Moreover, precise chemical modification of functional molecules and immobilization with metal nanoparticles, carbon nanostructures, and biomolecules could promote their electrochemical performances. In this Review, we focus on recent progress achieved in MOF research with respect to general sensing principles and analytical performances of electrochemical sensors. The evaluation and challenges governing the detection of the assays are also discussed.
