Abstract Buckminsterfullerene (C 60 ) and derivatives are significant in the synthesis of efficient electrocatalysts photocatalysts. This is because electron acceptor properties distinctive heterostructure(s) physicochemical characteristics. High‐performance photocatalysts important therefore conversions for clean energy. Here a critical assessment advances use C as heterostructures “electron buffers” catalysts reported. Methodologies preparing composite assessed categorized microscopic mechanisms boosting catalytic performance through materials including, semiconductors, carbon‐based metal‐free materials, metal nanoclusters, single atoms, metal–organic skeletons established. Important characterizations used with derivative composites contrasted practical challenges to development determined. A prospective on future directions likely outcomes high efficiency provided. It concluded that advantageous advanced structural integrity boosted transport. The findings expected be interest benefit researchers manufacturers formation buffer areas significantly performance.

The nitrogen reduction reaction (NRR) for ammonia synthesis is hindered by weak N2 adsorption/activation abilities and the hydrogen evolution (HER). In this study, αBi2O3 (monoclinic) βBi2O3 (tetragonal) were first synthesized calcination at different temperatures. Experiments calculations revealed effects of Bi2O3 with crystal phases on HER. Then, αBi2O3-x βBi2O3-x series catalysts surface oxygen vacancies (OVs) Bi0 active sites through partial in situ method. results demonstrate following: (I) Tetragonal can better adsorb cleave N≡N bond, thereby obtaining a lower NRR rate-limiting energy barrier (*N≡N → *N≡N–H, 0.51 eV). Meanwhile, effectively suppress HER limiting proton adsorption (H+ + e– *H, 0.54 Therefore, exhibit higher NH3 yield FE than αBi2O3-x. FTIR further confirms that could adsorb/activate N2, distal mechanism occurs surface. (II) introduction NaBH4 promotes conversion part Bi3+ into releases OVs. additional (OVs Bi0) enhance overall catalyst's capacity increasing FE. semimetal limit electron accessibility, inhibiting combination charges adsorbed protons, reducing improving NRR. improved catalysts. After optimization, βBi2O3-0.6 catalyst has best performance (NH3 yield: 51.36 μg h–1 mg–1cat.; FE: 38.67%), which superior to majority bismuth-based This work not only studies but also regulates components surface, realizing efficient reaction, provide valuable insights rational design Bi-based electrocatalysts.
