MOF-derived carbon-coated cuprous phosphide nanosheets for electrocatalytic glucose oxidation

Abstract

The exploitation of cheap and stable electrode materials to improve the electrocatalytic detection of blood glucose has recently been attracting much attention. Herein, a type of carbon-coated cuprous phosphide (Cu3P)...

Advances in functional guest materials for resistive gas sensors

“…MOFs are a unique crystalline and porous solid materials composed of metal nodes (metal ions or clusters) and functional organic ligands. 50 MOFs have been investigated extensively for numerous applications (such as gas storage, 115,116 catalysis, 117 and chemical sensors [118][119][120] ) in recent years, due to their large surface areas, tunable pore sizes and abundant functionalizable sites. 50 Nevertheless, many MOFs have relatively low conductivity, meaning that single MOF materials cannot act as host sensing materials for resistive gas sensors.…”

Research progress of flexible pressure sensor based on MXene materials

“…[9][10][11] In recent years, various nanomaterials such as graphene, carbon nanotubes, metal nanowires, carbon black, MXene, and various MOFs have been used as sensing materials to develop exible pressure sensors with excellent sensitivity. [12][13][14][15][16][17][18][19] MXene is a type of two-dimensional layered nanomaterial characterized by its general chemical formula M n+1 X n T x (n = 1, 2, 3), where M represents transition metals (such as Sc, Ti, Zr, V, Nb, etc. ), X represents carbon and/or nitrogen, and T x represents surface functional groups (such as -OH, ]O, -F, etc.).…”

Partially Oxidized Carbon Nanomaterials with Ni/NiO Heterostructures as Durable Glucose Sensors

“…Nonenzymatic electrochemical glucose-sensing materials with high accuracy, sensitivity, and efficiency have been conveniently prepared based on relatively inexpensive and abundant transition metals (TMs) . Meanwhile, TM-based compounds, such as metal nitrides, oxides/hydroxides, phosphides, and so forth, have been demonstrated to provide rapid and sensitive responses toward glucose detection. − On the other hand, it is well known that TM-based coordination polymers show a wider range of applications. , They are often used as precursors and/or templates to fabricate metal–carbon nanomaterials with different structures and morphologies for energy storage as well as heterogeneous catalysis. − However, with the continuous reaction using TM-based electrocatalysts for long-term chemical sensing, their overall nanostructures would be gradually destroyed and degraded, resulting in a slow disappearance of active species . Therefore, nonenzymatic catalysts derived from TM-based coordination polymers need to be endowed with high activity as well as structural stability.…”
