A free-standing and flexible phosphorus/nitrogen dual-doped three-dimensional reticular porous carbon frameworks encapsulated cobalt phosphide with superior performance for nitrite detection in drinking water and sausage samples

Nickel/Cobalt Molybdate Hollow Rods Induced by Structure and Defect Engineering as Exceptional Electrode Materials for Hybrid Supercapacitor

“…Along with the increasing concerns of the environmental pollution and the urgent need of renewable energy sources, [1–9] Supercapacitors (SCs) emerge as a compelling green energy solution with superior specific capacitance, prominent rate performance, high power density, and an extended lifetime [10–17] . Relying on charge storage mechanisms, SCs have been generally classified into electrical double‐layer‐type capacitors (EDLCs) and pseudocapactive‐type capacitors (PCs) [15–19] . Recently, increasing research efforts have focused on discovering pseudocapactive materials in view of these remarkable properties [20–24] …”

Preparation and Application of Keggin Polyoxometalate‐based 3D Coordination polymer Materials as Supercapacitors and Amperometric Sensors

“…Compared to these methods, the electrochemical method, as a new detection method, has its own attracted advantages, such as: simple-operation, short-time and low-cost and so on. [43,44] Because of the tunable redox properties, POM-based CPs materials could be used as an inexpensive amperometric sensors for detecting Cr [4-atrz = (4amino-triazole)] with variable POMs by a one-step hydrothermal synthesis method(Scheme 1). The main reasons for choosing this reaction system as follows: (i) Copper is a 3d transition metal, which has coordination diversity and flexibility.…”

Genomic DNA-mediated formation of a porous Cu2(OH)PO4/Co3(PO4)2·8H2O rolling pin shape bifunctional electrocatalyst for water splitting reactions

“…Researchers have prepared and amended different techniques to fabricate excellent catalysts, such as 2D NiCoFe, 1 cobalt phosphates (Co 3 (PO 4 ) 2 ), 2 (Co 5 (PO 4 ) 2 (OH) 4 ), 3 Fe 2 O 3 , 4 CuCo 2 S 4 /g-C 3 N 4 , 5 Co 2 -P@FePO 4 , 6 Au/ZnO, 7 Au/Cu, 8 Co 2 P/Co 2 N, 9 and DNA@Mn 3 (PO 4 ) 2 . 10 Among them, porous nanostructured materials, with high porosity, have exhibited impressive properties in several applications, for example catalysis, 6,[11][12][13][14] separation, 6,15 energy storage materials, [16][17][18] sensors, [19][20][21] and drug delivery. [22][23][24] Numerous synthesis methods, such as hydrothermal, 1 polymerization, 6 co-precipitation, 25,26 electrodeposition, 27,28 and direct calcination methods, 2 were utilized to prepare porous nanostructured materials.…”
