and textile. [2,7] It can be readily bound to biomolecules and consequently used as a strain to tissue and cells. [8] However, the application of abnormal level of EY becomes toxic and unfriendly to both the environment and living things. The development of reduction/degradation of nitro compound and dye is thus much needed to convert these materials into harmless products. For instance, the 4-NP and EY could be catalytically reduced into the formation of 4-aminophenol and reduced form of EY, respectively, and believe that this process could become potentially an effective way to treat 4-NP and EY in polluted water. Accordingly, the design and development of proficient catalyst are a significant task for the catalytic reduction of 4-NP and EY with aspects of the efficient and fast process. The nanomaterial-based catalysts are enormously developed for their superior catalytic performance in the reduction of pollutants. [9][10][11][12][13] In general, metal nanoparticles are usually adopted for the catalysis application; especially palladium nanoparticles (Pd NPs) exhibited excellent catalytic activities. [14][15][16] Such metal nanoparticles play a vital role in the catalytic reduction showing effective performance compared to other bare nanomaterials. In order to further improve their catalytic activity, the metal nanoparticles were incorporated with diverse nanomaterials including carbon-based materials, transition metal dichalcogenides (TMD), and porous organic cages. [17][18][19][20][21][22][23][24][25] Compared to other fluorescent nanomaterials, the C-dots can be easily synthesized from different kind of sources including organic molecules, biowastes, proteins, amino acids, and so on. [26][27][28][29][30][31][32] Moreover, the surface of C-dots can be modified with several capping agents to improve their fluorescence properties according to the applications. [33][34][35][36][37] That's why the C-dots have been extensively utilized in the fields of chemo-and biosensors, and optoelectronic applications. Thus far, the C-dots are much less utilized in the catalysis as in the sensing application. By taking advantage of C-dots and Pd NPs, this work aims to develop a superior multifunctional nanohybrid in the multiple applications including chemical sensor and catalysis.With this intention, we have synthesized carbon-dots to encapsulate palladium nanoparticles (Pd/C-dots) by the photochemical method. Prior to the synthesis of Pd/C-dots, Palladium nanoparticles encapsulated in the carbon dots (Pd/C-dots) are demonstrated to play a role of multifunctional nanohybrid in the synergetic applications of sensor and catalysis. The photochemical method is applied to synthesize Pd/C-dots in which Pd nanoparticles (NPs) are dispersedly encapsulated by C-dots layer. The nanohybrid can function as a fluorescent sensor and reductive catalyst, due to the inherent properties of C-dots and Pd NPs, respectively. The Pd/C-dots exhibit a highly selective and sensitive detection toward the nickel (Ni 2+ ) ion with a detection limit of ...

The lattice constants obtained from the HRTEM analysis were not consistent with either a pure Cu or Ni phase, indicating the formation of well-alloyed CuNi-oxide nanoparticles [24][25][26] . Other ring patterns may be due to the combination of Cu and Ni oxides (combination of two or more forms -Cu 2 O, NiO, Ni 2 O 3 , or CuO).…”

Aryl nitriles are versatile compounds that can be synthesized via transition-metal-mediated cyanation of aryl halides. Most of the supported-heterogeneous catalysts are noble-metals based and there are very limited numbers of efficient non-noble metal based catalysts demonstrated for the cyanation of aryl halides. Herein, bimetallic CuNi-oxide nanoparticles supported graphene oxide nanocatalyst (CuNi/GO-I and CuNi/GO-II) has been demonstrated as highly efficient system for the cyanation of aryl halides with K 4 [fe(cn) 6 ] as a cyanating agent. Metal-support interaction, defect ratio and synergistic effect with the bimetallic nanocatalyst were investigated. To our delight, the CuNi/GO-I system activity transformed a wide range of substrates such as aryl iodides, aryl bromides, aryl chlorides and heteroaryl compounds (Yields: 95-71%, TON/TOF: 50-38/2 h −1 ). Moreover, enhanced catalytic performance of CuNi/GO-I and CuNi/GO-II in reduction of 4-nitropehnol with NaBH 4 was also confirmed (k app = 18.2 × 10 −3 s −1 with 0.

“…The very slight change in performance of the catalyst with each cycle might be due to the reduction in catalytic active sites. [100] Further, our catalyst was not light-sensitive; this was determined by leaving the recovered catalyst at room temperature for 48 h. It was found that there was no change in colour observed in the recovered catalyst. This study demonstrated the light-insensitivity of the assynthesized catalyst after recycling.…”

The effect of varied zirconium content on the structural, morphological, magnetic, optical, thermal and catalytic properties of nanoparticles of the ferrite Cu1 − xZrxFe2O4 (x = 0, 0.5, 1) was investigated. The mixed ferrite was synthesized by the auto‐combustion method using nitrates of respective metals and citric acid as a chelating agent. The as‐prepared nanoparticles showed dual benefits. They were employed as a heterogeneous catalyst for one‐pot synthesis of polysubstituted pyridine derivatives as well as for catalytic degradation of industrial waste dyes such as methylene blue (MB). The highlight of the research reported is the catalytic degradation of industrial waste (MB) with high efficiency in eluent of a wide range of pH (3–13). The proposed nanoparticles arguably offer certain great advantages that include: low cost, facile nature, anti‐leaching property, magnetic recoverability and recyclability. The characterization of the as‐synthesized nanoparticles was done using various techniques. The leaching study was carried out using inductively coupled plasma optical emission spectroscopy. The formation of organic products was confirmed using Fourier transform infrared and 1H NMR spectroscopies and examination of degradation products of MB dye was carried out using mass spectrometry and UV–visible spectroscopy.
