“…Moreover, the surface area of 2-CuS NCs (28.3 m 2 g −1 ) was much larger than that of 1-CuS NCs (10.03 m 2 g −1 ). Furthermore, 2-CuS NCs also had larger surface area compared with the previously reported CuS materials, including nanosheets [22], nanoplates [23], nanoflowers [24], and nanospheres [25]. Generally, high porous volume and large surface areas benefited the accessibility of reactant molecules to the inner shells of 2-CuS NCs, leading to enhanced electrocatalytic activity.…”

Although transition metal sulfides have presented prospect in electrochemical sensing, their electrocatalytic performance still cannot meet the demands for practical applications due to the difficulties in mass transport and electron transfer. In this work, double-shelled CuS nanocages (2-CuS NCs) were prepared for enzyme-free ascorbic (AA) sensor through a Cu 2 O-templated method. The unique double-shelled hollow structure displayed large specific surface areas, ordered diffusion channels, increased volume occupying rate, and accelerated electron transfer rate, resulting in enhanced electrochemical dynamic. As a sensing electrode for AA, 2-CuS NCs modified glassy carbon electrode (2-CuS NCs/GCE) exhibited eminent electrocatalytic activity in terms of satisfying sensitivity (523.7 μA mM −1 cm −2 ), short response time (0.31 s), and low limit of detection (LOD, 0.15 μM). 2-CuS NCs look promising for analytical sensing of AA in electrochemical sensors thanks to its prominent electrocatalytic kinetics issued from double-shelled hollow porous structure.

“…In addition, the aerogels prevent Ni 3 N aggregation and thus increases the active sites for electrocatalysis. In short, the results demonstrated that the prepared sensor with an efficient conductive nature is applicable for perfect charge transfer and avoided the agglomeration problems, which is a huge benefit for non-enzymatic electrocatalytic application [36].…”

Progress of Advanced Nanomaterials in the Non-Enzymatic Electrochemical Sensing of Glucose and H2O2

et al. 2020

Non-enzymatic sensing has been in the research limelight, and most sensors based on nanomaterials are designed to detect single analytes. The simultaneous detection of analytes that together exist in biological organisms necessitates the development of effective and efficient non-enzymatic electrodes in sensing. In this regard, the development of sensing elements for detecting glucose and hydrogen peroxide (H2O2) is significant. Non-enzymatic sensing is more economical and has a longer lifetime than enzymatic electrochemical sensing, but it has several drawbacks, such as high working potential, slow electrode kinetics, poisoning from intermediate species and weak sensing parameters. We comprehensively review the recent developments in non-enzymatic glucose and H2O2 (NEGH) sensing by focusing mainly on the sensing performance, electro catalytic mechanism, morphology and design of electrode materials. Various types of nanomaterials with metal/metal oxides and hybrid metallic nanocomposites are discussed. A comparison of glucose and H2O2 sensing parameters using the same electrode materials is outlined to predict the efficient sensing performance of advanced nanomaterials. Recent innovative approaches to improve the NEGH sensitivity, selectivity and stability in real-time applications are critically discussed, which have not been sufficiently addressed in the previous reviews. Finally, the challenges, future trends, and prospects associated with advanced nanomaterials for NEGH sensing are considered. We believe this article will help to understand the selection of advanced materials for dual/multi non-enzymatic sensing issues and will also be beneficial for researchers to make breakthrough progress in the area of non-enzymatic sensing of dual/multi biomolecules.

“…Noticeable lattice fringes for Ni 3 N (002) (0.22 nm) were observed in the high-resolution TEM (HRTEM) images (Figure 2(d)), which further confirmed the formation of Ni 3 N in the spent Ni 2 Al-600. [31] In situ XPS was used to investigate the surface chemical state of the freshly reduced and spent Ni 2 Al-600 catalysts. As depicted in Figure 3 peak was present at 869.6 eV, with a weak satellite peak at 875.1 eV, representing a typical mixture of core level and satellite features for metallic Ni, which indicated that the Ni species was completely reduced to Ni 0 .…”

Direct Amination of Biomass‐based Furfuryl Alcohol and 5‐(Aminomethyl)‐2‐furanmethanol with NH₃ over Hydrotalcite‐derived Nickel Catalysts via the Hydrogen‐borrowing Strategy

et al. 2021

View full text Add to dashboard Cite

A series of hydrotalcite-derived nickel catalysts were synthesized and employed for the direct amination of biomass-based furfuryl alcohol with NH 3 via the hydrogen borrowing strategy. The effects of the Ni/Al molar ratio and calcination temperature of the NiAl hydrotalcite-like precursors on the performance of the Ni x Al-CT catalyst were investigated. The systematic characterization showed that the synergistic catalysis of the metal and acid-base sites was of vital importance for the amination of alcohols. In particular, the Ni 2 Al-600 catalyst with high amount of Ni 0 sites (1.26 mmol g À 1 ) and suitable density of acid-base sites (0.71 mmol g À 1 and 1.10 mmol g À 1 , respectively) exhibited the best dehydrogenation capability and therefore excellent catalytic activity. An 84.1 % yield of furfurylamine with complete conversion of furfuryl alcohol was obtained under the reaction conditions of 180°C and 0.4 MPa NH 3 in 36 h. The presence of Ni 3 N in the spent catalyst, confirmed by XRD, TEM and XPS characterizations, was demonstrated to be responsible for the deactivation of the Ni x Al-CT catalyst. In addition, the Ni 2 Al-600 catalyst exhibited satisfactory performance toward another important biomass-related transformation of 5-(aminomethyl)-2-furanmethanol to 2,5-bis(aminomethyl)furan, with a yield of 70.5 %.
