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.

“…A hybrid of Cu‐MOFs/porous carbon was synthesized by hydrothermal treatment and displayed excellent electrocatalytic ability for the reduction of hemoglobin and the oxidation of ascorbic acid compared to the individual counterparts . A simple one‐step hydrothermal method was also developed to synthesize porphyrinic iron‐based MOF/porous carbon, and the hybrid materials provided more active sites to reduce H 2 O 2 . In addition, acetylene black as one special type of carbon black was introduced to the Cu‐MOFs and exhibited good electrocatalytic activity towards H 2 O 2 reduction due to their active metal sites and diverse structures …”

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.

“…In 2017, Liu et al used a porphyrinic iron metal-organic framework decorated with ordered mesoporous carbon to create an enzyme-free H 2 O 2 sensor [72]. Liu et al's sensor was successfully used to observe the H 2 O 2 levels in HeLa cells after exposure to CdTe quantum dots, which cause cells to produce increased levels of ROS [72][73][74][75].…”

Hydrogen peroxide (H2O2) is an important molecule within the human body, but many of its roles in physiology and pathophysiology are not well understood. To better understand the importance of H2O2 in biological systems, it is essential that researchers are able to quantify this reactive species in various settings, including in vitro, ex vivo and in vivo systems. This review covers a broad range of H2O2 sensors that have been used in biological systems, highlighting advancements that have taken place since 2015.
