The Design of a New Cobalt Sulfide Nanoparticle Implanted Porous Organic Polymer Nanohybrid as a Smart and Durable Water‐Splitting Photoelectrocatalyst

“…86-2273) as well as ac ubic CoS 2 phase (JCPDS no. [29] We have conducted FTIR and solids tate 13 CC PM AS NMR spectroscopy analysisi n order to elucidate the nanostructure compositiona nd different chemicale nvironments of carbon nuclei of the respective POP based nanohybrid materials. In addition, an obvious significant suppression of the broad peak at 2q = 20.28,i ndicativef or carbon in CoS x @POP was noticed, presumably because of the loading of cobalt sulfide on the POP framework with very high density.…”

“…The same phenomenonw as observed by Bhaumik et al after functionalisation of aromatic rings of nitrogen rich POP with ÀSO 3 Hg roups. [29] We have conducted FTIR and solids tate 13 CC PM AS NMR spectroscopy analysisi n order to elucidate the nanostructure compositiona nd different chemicale nvironments of carbon nuclei of the respective POP based nanohybrid materials. The broad band in FTIR spectrum of Co 3 O 4 @POP centred at 1273 cm À1 corresponds to the CÀN stretching frequency of the tertiary amine and the sharp peak near 815 cm À1 is assignable to the characteristic CÀHo ut-ofplane bending of the para-disubstituted benzene rings of the porousp olytriphenylaminem aterial ( Figure 1C), indicating that the main spectrum is extremelya nalogous with the as-synthesised POP.B esides, the bands for both nanohybridm aterials observeda ta round 2900, 1596 and 1487 cm À1 confirms the presenceo fp henylic CÀHb ond anda romatic C=Cs tretching vibration of the benzene ring of the parent POP unit.…”

An overview on recent advances in the synthesis of sulfonated organic materials, sulfonated silica materials, and sulfonated carbon materials and their catalytic applications in chemical processes

“…In addition to the catalytic role of strong acid strength, the high surface area may play a role in catalysis. The catalyst was reused up to five cycles [ 69 ].…”

Novel marine‐based gold nanocatalyst in solvent‐free synthesis of polyhydroquinoline derivatives: Green and sustainable protocol

“…Polyhydroquinoline (PHQ) compounds are considered as a privileged skeleton for various N‐heterocyclic derivatives, and because of their promising pharmacological and biological activities, they were broadly investigated as neurotropic, anticancer, antitubercular, and antidiabetic activities [ 25 ] (Scheme 1). Owing to these distinct features, PHQ nucleus unites have received considerable attention in medicinal chemistry such as antitumor and vasodilator [ 26,27 ] ; hence, significant attempts have been devoted to innovating straightforward synthetic methods targeting compounds possessing the PHQ core.…”
