Soft template-mediated coupling construction of sandwiched mesoporous PPy/Ag nanoplates for rapid and selective NH₃ sensing

Abstract

Synchronous construction of heterogeneous materials from distinct molecular units into functional hybrids within one synthesis system holds large potential for customizing properties and applications, but which requires the elaborate coordination...

Simplified fast synthesis of strong-coupling composite supercapacitor materials by one-step bipolar pulse electrodeposition

“…The high-intensity peak at 1559 cm À1 is attributed to the symmetric stretching of the aromatic C]C ring, the peak at 1345 cm À1 is related to the ring-stretching mode of PPy, the peak at 1053 cm À1 is attributed to C-H inplane deformation, and the peak at 940 cm À1 corresponds to the C]C backbone stretching, indicating the successful polymerization of PPy. [48][49][50] In addition to that, it can be seen that there are three distinct peaks at 471, 512 and 674.5 cm À1 , which are caused by Co 9 S 8 . [51][52][53] Meanwhile, the Fourier transform infrared (FTIR) spectra in Fig.…”

Block Copolymer Self‐Assembly Guided Synthesis of Mesoporous Carbons with In‐Plane Holey Pores for Efficient Oxygen Reduction Reaction

“…Self-assembly of block copolymers (BCPs) is a versatile method to construct diverse ordered nanostructures, [1][2][3][4][5][6] which provide ideal pore-directing soft templates for preparing porous materials. [7][8][9][10][11][12][13][14] For example, porous carbons have been broadly employed in energy storage and conversion devices thanks to their satisfied electrical conductivity, high specific surface area (SSA), and structural stability. [15][16][17] Among many energy conversion devices, fuel cells convert chemical energy to electrical energy, in which oxygen reduction reaction (ORR) is the key step DOI: 10.1002/marc.202100884 to achieve this conversion.…”

Multi‐Dimensional Molecular Self‐Assembly Strategy for the Construction of Two‐Dimensional Mesoporous Polydiaminopyridine and Carbon Materials

“…In comparison, the molecular self‐assembly strategy using block copolymers as templates is a more promising method of preparing 2D mesoporous polymers. [ 19,25,36–38,43 ] For example, Feng and Mai et al. reported the one‐step synthesis of 2D mesoporous polypyrrole and polydopamine employing block copolymers polystyrene‐ b ‐poly(ethylene oxide) (PS‐ b ‐PEO) and P123 (poly(ethylene oxide) 20 ‐block‐poly(phenylene oxide) 70 ‐blockpoly(ethylene oxide) 20 ) respectively.…”

[43,45] However, the currently developed 2D mesoporous polymers are very limited owing to the following issues: a) Few types of precursor molecules and 2D substrates are available for polymers.…”
