“…The N 2 adsorption‐desorption isotherm (Figure 3d) demonstrated that the Brunauer–Emmett–Teller (BET) specific surface areas of the as‐prepared CoP, Cu 2 P 7 ‐CoP (1 : 4), Cu 2 P 7 ‐CoP (1 : 5) and Cu 2 P 7 ‐CoP (1 : 6) were 4.04, 8.23, 21.97 and 4.70 m 2 g −1 , respectively, indicating that Cu 2 P 7 ‐CoP (1 : 5) had the largest specific surface area. From TEM images (Figure 2b, Figure S8‐10), it can be seen that Cu 2 P 7 ‐CoP (1 : 5) nanosheets have more pores than other samples, so Cu 2 P 7 ‐CoP (1 : 5) nanosheets have the largest BET comparison area [39–41] . The pore size distribution indicated that the synthesized Cu 2 P 7 ‐CoP (1 : 5) nanosheets possessed mesoporous microstructure (Figure S11).…”

Electrooxidation of 5-hydroxymethylfural (HMF) into 2,5-furandicarboxylicacid (FDCA) has been regarded as a promising sustainable approach to achieve value-added chemicals. However, it is still impeded by the unsatisfactory performance of electrocatalysts. Here, Cu 2 P 7 -CoP heterostructure nanosheets were reported to enable powerful HMF electrooxidation. The Cu 2 P 7 -CoP heterostructure nanosheets were fabricated by microwave-assisted deep eutectic solvent (DES) approach, along with subsequent phosphiding. The Cu 2 P 7 -CoP heterostructure nanosheets enabled a superb 100 % HMF conversion at 1.43 V (vs. RHE) with 98.8 % FDCA yield and 98 % Faradaic efficiency (FE), demonstrating its promising application in HMF electrooxidation. X-ray photoelectron spectroscopy (XPS) analysis, open-circuit potential (OCP) approach and density functional theory (DFT) calculation uncovered that the electron transfer and redistribution between Cu 2 P 7 and CoP improved the adsorption capacity of HMF and modulated the catalytic performance. This study not only offered a powerful electrocatalyst for HMF electrooxidation, but also provided a conceptually new strategy for the heterostructure catalyst design.

“…Carbon-based, metalfree catalysts are however potential practical substitutes for noble metal-based catalysts because of good catalytic activity, selectivity and stability. [225][226][227][228][229][230] It is concluded that C 60 and derivatives are significant to development of increasingly efficient and advanced electrocatalysts and photocatalysts. This is because of electron acceptor properties, distinctive heterostructure(s) and physicochemical characteristics and electron buffers, together with high structural integrity.…”

Buckminsterfullerene (C60) and derivatives are significant in the synthesis of efficient electrocatalysts and photocatalysts. This is because of electron acceptor properties and distinctive heterostructure(s) and physicochemical characteristics. High‐performance electrocatalysts and photocatalysts are important therefore in conversions for clean energy. Here a critical assessment of advances in use of C60 and derivatives as heterostructures and “electron buffers” in catalysts are reported. Methodologies for preparing C60 composite catalysts are assessed and categorized and microscopic mechanisms for boosting catalytic performance through C60 and derivatives in important catalytic materials including, semiconductors, carbon‐based metal‐free materials, metal nanoclusters, single atoms, and metal–organic skeletons are established. Important characterizations used with C60 and derivative composites are contrasted and assessed and practical challenges to development are determined. A prospective on future directions and likely outcomes in development of high efficiency electrocatalysts and photocatalysts is provided. It is concluded that C60 and derivatives are advantageous for advanced electrocatalysts and photocatalysts with high structural integrity and boosted electron transport. The findings are expected to be of interest and benefit to researchers and manufacturers for formation of heterostructures and electron buffer areas for significantly boosted catalytic performance.

“…Ni-based catalysts are some of the most excellent catalysts for catalyzing the oxidation of HMF, and various Ni-based materials show good catalytic activity because of their appropriate electronic configuration, rich valence states and diverse composition. 29,30 Driven by ions, the Ni metal will be oxidized to a high valence state, and then it will spontaneously and quickly return to the original Ni 2+ , which is the process of anodizing. 31,32 The results show that the more high-valence the Ni forms, the more the active sites formed, thus improving the performance of the catalyst.…”
