“…This may be due to strong electronegativity of Pt atom, which attracts more electrons through the Pt–O–Cu bond. [ 41 ] Two peaks of Pt 4f 5/2 and Pt 4f 7/2 at 74.9 and 71.8 eV are observed in the XPS spectra of Pt 4f in Figure 2d, while the other two peaks at 76.1 and 78.4 eV in Figure 2d correspond to Cu(II) 3p 1/2 and 3p 1/2 , respectively. Additionally, the peak of Pt 4f 7/2 in Pt 1 /Cu@CuO NWs is between those of PtO 2 (74.7 eV) and Pt (70.9 eV).…”

Diabetes Federation. [3] For quick patient screening and medical monitoring, it is crucial to develop fast and accurate sensors for glucose detection. [4] The commercial glucose sensors are electrochemical enzymatic based, but they have limitations, such as susceptible to deterioration from environmental influence (pH, temperature, and humidity) and poor stability due to inactivation of enzymes. [5] Therefore, electrochemical nonenzymatic glucose sensors have received increasing attention for the next-generation sensing applications. One option is to use noble metals (Pt, Pd, Au, etc.) and their alloys [6][7][8][9][10][11] as modified electrodes toward electrochemical glucose sensing. However, their commercial applications are limited by high cost and scarcity. Therefore, it is critical to develop highly efficient and lowcost electrocatalysts, based on non-noble metals. [12] Previously, Ni, Co, and Cu have been extensively used for electrochemical nonenzymatic glucose sensing. [13][14][15] Especially, the Cu-based catalysts are desirable due to their low-cost, high electrical conductivity, nontoxicity, and great electrocatalytic ability toward glucose. [16] Various Cu or CuO x nanostructures, such as nanoparticles, [17] nanorods, [18] flower-like structure, [19] have shown great potential of being used in electrochemical glucose sensing, attributing to high aspect ratio and high surface area. [20,21] For rational design of new Cu-based nanomaterials for nonenzymatic glucose sensing, fundamental research is needed to understand the catalytic mechanism and its impacts on sensing performance. [22] Single-atom catalysts (SACs) belong to a class of catalysts with specific characteristics of metal single atoms immobilized on supporters, [23][24][25][26] which provide high catalytic activity and selectivity in various catalytic reactions due to their unsaturated coordination environment and unique electronic structure. [27][28][29][30][31] The 100% atom utilization of metal also maximizes atomic economy. [32] Moreover, the identified active centers and structural simplicity could be ideal model for understanding the relationship between the structure and catalytic activity, with which one can use for rational design of atomic-scale catalyst targeting at specified reaction. [33,34] In addition, the use of SACs for electrochemical sensing [35][36][37][38] is still in the early stage of development, with much questions related to the sensing It is critical to develop high-performance electrocatalyst for electrochemical nonenzymatic glucose sensing. In this work, a single-atom Pt supported on Cu@ CuO core-shell nanowires (Pt 1 /Cu@CuO NWs) for electrochemical nonenzymatic glucose sensor is designed. Pt 1 /Cu@CuO NWs exhibit excellent electrocatalytic oxidation toward glucose with 70 mV lower onset potential (0.131 V) and 2.4 times higher response current than Cu NWs. Sensors fabricated using Pt 1 / Cu@CuO NWs also show high sensitivity (852.163 µA mM −1 cm −2 ), low detection limit (3.6 µM), wide linear range (0.01-5.18 µM...

“…This linkage is responsible for the activity by creating additional vacancies on the surface of ceria. 70,71 The groups of exposed Ce 3+ ions on Ce x O y are potentially potent surface sites for catalytic reactions as adsorbed reactants or reaction intermediates could interact simultaneously with several Ce 3+ ions.…”

“…Among different pollutants with subsequent harmful effects, such as carbon monoxide, ammonia, NO x , SO x , and particulate matter, are also volatile organic compounds (VOCs) . Depending on the source of pollution with such organic matter, different techniques are applied, among which is also the catalytic oxidation of the exhaust fumes (flue gas). , There are two main groups of catalysts used for this operation: noble metals (working at 150–280 °C) and transition metal based (working at 280–450 °C). Noble metals require lower operating temperatures and, therefore, usually lower operation costs .…”

A γ-alumina support functionalized with transition metals is one of the most widely used industrial catalysts for the total oxidation of volatile organic compounds (VOCs) as air pollutants at higher temperatures (280–450 °C). By rational design of a bimetal CuFe-γ-alumina catalyst, synthesized from a dawsonite alumina precursor, the activity in total oxidation of toluene as a model VOC at a lower temperature (200–380 °C) is achieved. A fundamental understanding of the catalyst and the reaction mechanism is elucidated by advanced microscopic and spectroscopic characterizations as well as by temperature-programmed surface techniques. The nature of the metal–support bonding and the optimal abundance between Cu–O–Al and Fe–O–Al species in the catalysts leads to synergistic catalytic activity promoted by small amounts of iron (Fe/Al = 0.005). The change in the metal oxide–cluster alumina interface is related to the nature of the surfaces to which the Cu atoms attach. In the most active catalyst, the CuO6 octahedra are attached to 4 Al atoms, while in the less active catalyst, they are attached to only 3 Al atoms. The oxidation of toluene occurs via the Langmuir–Hinshelwood mechanism. The presented material introduces a prospective family of low-cost and scalable oxidation catalysts with superior efficiency at lower temperatures.
