“…Oxygen evolution reaction (OER) is the anodic reaction of water splitting, which is suitable for various sustainable energy conversion and storage technologies such as hydrogen production and carbon dioxide reduction. − Compared to the hydrogen evolution reaction (HER), which is a two-electron process, OER is a four-electron process involving multiple subreactions, which results in a high energy barrier and slower kinetics for water splitting. − Accelerating the widespread application of water electrolysis technology is crucial to meet the growing demand for sustainable green energy solutions . Hence, the development of highly active OER catalysts is of paramount importance and poses significant challenges.…”

Iron-based metal−organic frameworks (MOFs) have shown potential as catalysts for the electrocatalysis oxygen evolution reaction (OER). Despite numerous methods being employed to enhance the OER performance of MOFs, the influence of halogen-containing linkers on the electronic structure of iron-based MOF catalysts remains unexplored. In this study, a series of Fe-based MOFs (denoted as MOF-R, where R = H, Cl, or Br) with comparable structures are synthesized by changing the organic linkers coordinated with the Fe metal active center, with the aim of investigating the influence of halogen-containing linkers on the OER activity. Significantly, MOF-Br exhibited superior OER activity compared to MOF-Cl and MOF-H. Density functional theory calculations reveal that the tuning of halogen groups on organic linkers can modulate the electronic structure of the metal active sites and effectively regulate the adsorption behavior of key intermediates near the optimal d-band center, leading to the enhancement of electroactivity. Notably, the brominesubstituted MOF-Br catalyst displayed remarkable intrinsic OER activity, including a low overpotential of 251.2 mV at a current density of 10 mA cm −2 and a low Tafel slope of 44.5 mV dec −1 , surpassing the halogen-unsubstituted MOF-H (262.6 mV and 63.4 mV dec −1 ) and commercial IrO 2 (335.3 mV and 98.6 mV dec −1 ). Moreover, the high turnover frequency at an overpotential of 300 mV was measured to be 0.537 s −1 , which is 30 times greater than that of the commercial IrO 2 catalyst (0.018 s −1 ). This research offers a potential strategy for designing MOF electrocatalysts with superior OER activity, laying a solid foundation for the rational design and synthesis of excellent OER electrocatalysts in the future.

Fermentation is an oxygen-free biological process that produces hydrogen, a clean, renewable energy source with the potential to power a low-carbon economy. Bibliometric analysis is crucial in academic research to evaluate scientific production, identify trends and contributors, and map the development of a field, providing valuable information to guide researchers and promote scientific innovation. This review provides an advanced bibliometric analysis and a future perspective on fermentation for hydrogen production. By searching WoS, we evaluated and refined 62,087 articles to 4493 articles. This allowed us to identify the most important journals, countries, institutions, and authors in the field. In addition, the ten most cited articles and the dominant research areas were identified. A keyword analysis revealed five research clusters that illustrate where research is progressing. The outlook indicates that a deeper understanding of microbiology and support from energy policy will drive the development of hydrogen from fermentation.

“…The cyclic reduction/re-oxidation of metal oxide (M x O y ) materials forms the backbone of a vast number of chemical processes, such as gas reforming, 1,2 gas separation and pumping, 3–9 energy production and storage, 10–17 and many catalytic processes, particularly those which operate on Mars-van Krevelen-like mechanisms. 18–24 The performance of these materials is directly related to their partial molar reduction thermodynamics, i.e.…”
