N-doped carbon coated Mn3O4/PdCu nanocomposite as a high-performance catalyst for 4-nitrophenol reduction

CeO2@N/C@TiO2 Core‐shell Nanosphere Catalyst for the Aerobic Oxidation of 5‐Hydroxymethylfurfural to 5‐Hydroxymethyl‐2‐Furancarboxylic Acid

“…The TGA curve shows a small mass loss in the range 85–200 °C, which can be attributed to the loss of surface physisorbed water [21] . A large mass loss was observed in 250–380 °C region, which is due to the conversion of the PDA coating into a nitrogen‐doped carbon (N/C coating) [22] . Coinciding with this mass loss was a large exothermic peak at 310 °C in the DTA curve.…”

Single Metal Atoms Anchored on N‐Doped Holey Graphene as Efficient Dual‐Active‐Component Catalysts for Nitroarene Reduction

“…Remarkably, the TOF of 4‐NP for the Pd 1 /NHG DACC is 97 times higher than that of the commercial Pd/C (5.0 wt.%) catalyst and greatly exceeds those of the control samples (i.e., NHG, Pd Cs /NHG, and Pd NPs /NHG), as well as those of recently reported carbocatalysts and metal‐based catalysts under similar reaction conditions (Figure 7d, and Figure S13, and Table S4, Supporting Information). [ 24,40–63 ]…”

“…At 926 s −1 g −1 , the activity factor k of the Pd 1 /NHG DACC greatly exceeds those of its NHG counterparts (Figure 7c and Figure S10b, Supporting Information) and previously reported SACs, [26][27][28][29][30][31] carbocatalysts, [32][33][34][35][36][37][38] and metal nanocatalysts (Table S5, Supporting Information). [39][40][41][42][43][44][45][46][47][48][49][50] Aside from the rate constant, the catalytic efficiency of the Pd 1 /NHG DACC can also be represented by its TOF, which is defined herein as the number of moles of 4-NP that 1 mg of catalyst can convert to 4-AP in 1 min. [13] The TOF value of the Pd 1 /NHG DACC can reach up to 2.0 min −1 , which is the highest value reported among all carbocatalysts and supported metal-based catalysts according to the mass activity of their active components.…”
