Metal–organic frameworks based on infinite secondary building units: recent progress and future outlooks

“…By taking the advantages of rich active sites, low resistance of mass transport and easy alternation of functionality, MOFs are also promising candidates for energy storage, 124 like being used as, the active electrodes for batteries 32,44,125–128 and the proton-conductive membrane 27,58,129–131 used in fuel cells. 132,133 More than those, the unique ISBU structures can bring additional merits ( e.g.…”

Recent progress of photocatalysts based on tungsten and related metals for nitrogen reduction to ammonia

“…Among various polyoxometalates, bismuth-based compounds such as Bi 2 WO 6 , Bi 2 MoO 6 of Aurivillius structure, and BiVO 4 of Scheelite structure, are another class of oxides of interest because of their considerable chemical stability, up-shifted VB resulting from hybridization between Bi 6s and O 2p states and narrow band gaps, Frontiers in Chemistry frontiersin.org together with their similar layered crystal structures complimentary for charge separation and transfer (Zhang et al, 2011;Hao et al, 2020;Wenjie Liu et al, 2020;Utomo et al, 2022). Besides, the hybridization of Bi 6s and O 2p levels accounts for their largely dispersed VB, benefiting the migration of photoinduced holes and thus improving the oxidative reactions (Huang et al, 2020) (Cooper et al, 2014;Dai et al, 2016;Zhu et al, 2022). Nevertheless, the potentially high NRR activities are profoundly impeded by their intrinsic shortcomings, such as the photo-corrosion susceptibility for Bi 2 WO 6 , the limited light absorption in the ultraviolet region for Bi 2 MoO 6 , the poor water oxidation kinetics and slow mobility of photo-excited charge carriers for BiVO 4 (Girish Kumar and Koteswara Rao, 2015;Xin Liu et al, 2020).…”

MoP2/C@rGO synthesised by phosphating the molybdenum-based metal organic framework and GO coating with excellent lithium ion storage performance

“…In recent years, with the rapid development of portable energy and new energy vehicles, the demand for sustainable energy storage equipment has risen sharply, 1–7 where rechargeable lithium-ion batteries (LIBs), with high energy density, safety and reliability, and good cycling performance, have attracted the most attention. 8–10 However, graphite, as a traditional anode material, cannot meet the current development demand due to its low Li storage capacity. 11–14 Therefore, finding high capacity anode materials is necessary to meet the needs of today's energy development.…”
