... The MoO x NPs immobilized on an activated carbon showed excellent activity for glucose epimerization to mannose. 237 The MoO x NPs (3.05 nm) were synthesized by oxidizing metal Mo using H 2 O 2 . Owing to the strong MoO x − glucose interaction, this catalyst outperformed several reported catalysts and can be used for 16 days under 24 V with stable catalytic activity, and a negligible amount of Mo (3.2% of total Mo) was leached into the reaction medium. ...

... We observed no metal aggregates in the final Au/(Si)C. Small metal particles with an interplanar distance of 0.235 nm related to the Au (111) crystal plane (Luo et al., 2019) confirmed the surface distribution of the Au particles. The irregular sheet-like carbon structure (arrows in Figures 2C and D) was ascribed to the destroyed multilayer carbon shells after silica etching. ...

... Electrocatalytic water splitting is a more practical technology than photocatalytic water splitting because it has a better conversion efficiency and higher hydrogen generation purity [14][15][16][17]. In general, water splitting demands significantly greater voltage than the theoretical voltage (1.23 V ) due to the slow kinetics of the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) of water electrolysis [18,19]. As a result, developing high-efficiency catalysts for decreasing the overpotential associated with the cathodic HER and anodic OER is critical for accelerating H 2 and O 2 generation [20][21][22]. ...

... Compton scattering is a well-established and unique tool to study the electronic structure of materials via their electron momentum density [22][23][24][25][26] . The shape of the Compton profile is sensitive to the state of the valence electrons of the atoms which combine to form the condensed phase of the material 7 . ...

... Carbon-based catalysts are promising alternatives to traditional transition metal and noble metal catalysts in various chemical reactions due to their unique advantages, including their abundant functional groups, tunable porosity, and morphology [4][5][6] . Compared with undoped nanocarbons, nitrogen-doped nanocarbons (NCs) are notable for their superior catalytic performance in the two abovementioned reactions [7][8][9][10] . However, key questions remain despite the progress in this field. ...

... [36] It has also been shown that small copper clusters deposited on ZnO are more active catalysts for the CO 2 hydrogenation to CO than the larger particles. [37] Copper subnano clusters have also been found to be active in CO 2 hydrogenation in various other surfaces, like Fe 2 O 3 [38] or TiO 2 . [39] Small tetraatomic metal clusters, [40] size selected sub-nanoclusters of first row transition metals [41] and copper clusters supported on boron doped graphene [36] have been predicted by DFT computations, while nitrogen doped graphene supported copper clusters [42] and Cu 5 and Cu 20 clusters on carbon [43] have been realized experimentally as good electrocatalysts. ...

... Thus, materials possessing isolated Pt sites with high thermal stability should be utilized for continuous working at a high temperature (! 600 8C). [8,10,[15][16][17][18][19][20][21] In the previous study, we observed that an isolated Pt atom (single-atom-like Pt, Pt 1 ) included in thermally stable intermetallic PtGa (Pt:Ga = 1:1, Space group of P2 1 3) [22] functioned as a highly selective and durable active site for PDH without sintering even at 600 8C. [8] Although PtGa contains the isolated Pt 1 and Pt 3 ensembles at the most stable (111) surface, the latter can be selectively blocked by Pb decoration (Scheme 1). ...

... The synthesis and application of noble metal nanoparticles is one of the most promising fields in nanotechnology. Palladium nanoparticles (PdNPs) have attracted huge and broad attention among noble metal nanoparticles because of their superior properties in the aspects of optics [1], electricity [2], magnetism [3] and catalysis [4]. A vast number of pure physical and chemical synthetic pathways including microwave [5], ultrasonic [6], sol-gel [7] and chemical co-precipitation [8] have been developed to synthesise PdNPs. ...

... For instance, the approach was utilized by Corey in 1970 for the total synthesis of erythronolide A [12], which is a progenitor of the eminent clinically essential antibacterial drug erythromycins [13]. The deoximation reaction plays a crucial part in product purification in the industrial manufacturing of watermelon ketone, as it readily crystallizes [14]. The deoximation reaction is also crucial for synthesizing ketones from non-carbonyl starting materials, such as carvone from limonene [15]. ...

... At present, in industry, VDF is usually produced via the dehydrochlorination of 1,1-difluoro-1-chloroethane (HCFC-142b) at reaction temperatures above 650 • C [3,4]. Dehydrochlorination is an efficient route for the preparation of 1, 1-dichloroethylene (VDC), vinyl chloride monomer (VCM), 2,3,3,3-tetrafluoropropene (HFO-1234yf), and ethylene oxychlorination [5][6][7][8]. As the dehydrochlorination of HCFC-142b is a highly endothermic reaction, very long reaction tubes are adopted to supply the reaction heat. ...
