A facile preparation method for new two-component supramolecular hydrogels and their performances in adsorption, catalysis, and stimuli-response

Abstract

New two-component supramolecular hydrogels were prepared via a self-assembly process, demonstrating potential applications in adsorption and catalysis as well as sensor materials.

Self-assembled functional components-doped conductive polypyrrole composite hydrogels with enhanced electrochemical performances

“…According to similar reports, this is because the oxygen-containing functional groups and organic groups of the polypyrrole sodium alginate composite hydrogel undergo thermal decomposition reactions. [27][28][29][30][31][32][33] For doped polypyrrole of dodecyl benzene sulfonic acid sodium alginate composite hydrogel, between 150-290 C weightlessness slower, it illustrates the addition of sodium dodecyl benzene sulfonic acid increased the polypyrrole sodium alginate composite hydrogel between thermal stability, at the same time, the polypyrrole chains with the combination of the chemical bonds between dodecyl benzene sulfonic acid sodium and also further improve the interaction between polypyrrole thermal stability of sodium alginate composite hydrogel. It is interesting to note that the thermogravimetric curve reaches a plateau at 290 C, where all the quality of the composite hydrogel remains relatively stable.…”

In Situ Construction of Ag/TiO2/g-C3N4 Heterojunction Nanocomposite Based on Hierarchical Co-Assembly with Sustainable Hydrogen Evolution

“…These consequences mean the significant improvement of photocatalytic activity in samples thanks to the nanoscale structure of g-C 3 N 4 and the well-established heterojunction in Ag/TiO 2 /g-C 3 N 4 . Specifically, one-dimensional, tube-like g-C 3 N 4 with the increased specific surface area can effectively avoid carrier aggregation, and provide many more catalytic active sites [48][49][50][51]. Moreover, the heterogeneous structure with nanometer size can reduce the charge diffusion length and effectively facilitate the separation process of charge carriers at the interface, which is also confirmed with the steady-state and transient fluorescence spectrum.…”

Fabrication of CS/GA/RGO/Pd composite hydrogels for highly efficient catalytic reduction of organic pollutants

“…Moreover, the raw materials and preparation process of CS/GA/RGO/Pd hydrogel are green, pollution-free and environmentally friendly. [68][69][70][71][72][73][74] Aer seven catalytic cycles, Fig. 8 shows that the catalytic efficiency of CS/GA/RGO/Pd composite hydrogel for the NaBH 4 and 4-NP mixture solution.…”
