--- _id: '64017' abstract: - lang: eng text: Abstract Donor stabilization of Sn(II) and Pb(II) halides with 1,1?-ferrocenylene bridged bisphosphanes has been explored for Fe(C5H4P(C6H5)2)2 (dppf), and Fe(C5H4PH(C4H9))2. These bisphosphanes are reacted with SnBr2 and PbCl2 with and without additional Lewis acid (AlCl3) forming acyclic and cyclic donor adducts from which the latter represent bisphosphoniotetrylenes. Since dynamic exchange in solution is observed, characterization includes solution and solid-state NMR in addition to SC-XRD, amended by DFT calculations. author: - first_name: Sina full_name: Nasemann, Sina last_name: Nasemann - first_name: Roman full_name: Franz, Roman last_name: Franz - first_name: Denis full_name: Kargin, Denis last_name: Kargin - first_name: Clemens full_name: Bruhn, Clemens last_name: Bruhn - first_name: Zsolt full_name: Kelemen, Zsolt last_name: Kelemen - first_name: Torsten full_name: Gutmann, Torsten id: '118165' last_name: Gutmann - first_name: Rudolf full_name: Pietschnig, Rudolf last_name: Pietschnig citation: ama: Nasemann S, Franz R, Kargin D, et al.

Herein, guided by density functional theory (DFT) calculations, an efficient metal-free electrocatalyst is demonstrated via covalently bonding BP nanosheets with graphitic carbon nitride (denoted BP-CN-c). The polarized PN covalent bonds in BP-CN-c can efficiently regulate the electron transfer from BP to graphitic carbon nitride and significantly promote the OOH* adsorption on phosphorus atoms. Impressively, the oxygen evolution reaction performance of BP-CN-c (overpotential of 350 mV at 10 mA cm−2, 90\% retention after 10 h operation) represents the state-of-the-art among the reported BP-based metal-free catalysts. Additionally, BP-CN-c exhibits a small half-wave overpotential of 390 mV for oxygen reduction reaction, representing the first bifunctional BP-based metal-free oxygen catalyst. Moreover, ZABs are assembled incorporating BP-CN-c cathodes, delivering a substantially higher peak power density (168.3 mW cm−2) than the Pt/C+RuO2-based ZABs (101.3 mW cm−2). The acquired insights into interfacial covalent bonds pave the way for the rational design of new and affordable metal-free catalysts. author: - first_name: Xia full_name: Wang, Xia last_name: Wang - first_name: Ramya full_name: Kormath Madam Raghupathy, Ramya id: '71692' last_name: Kormath Madam Raghupathy orcid: https://orcid.org/0000-0003-4667-9744 - first_name: Christine Joy full_name: Querebillo, Christine Joy last_name: Querebillo - first_name: Zhongquan full_name: Liao, Zhongquan last_name: Liao - first_name: Dongqi full_name: Li, Dongqi last_name: Li - first_name: Kui full_name: Lin, Kui last_name: Lin - first_name: Martin full_name: Hantusch, Martin last_name: Hantusch - first_name: Zdeněk full_name: Sofer, Zdeněk last_name: Sofer - first_name: Baohua full_name: Li, Baohua last_name: Li - first_name: Ehrenfried full_name: Zschech, Ehrenfried last_name: Zschech - first_name: Inez M. full_name: Weidinger, Inez M. last_name: Weidinger - first_name: Thomas full_name: Kühne, Thomas id: '49079' last_name: Kühne - first_name: Hossein full_name: Mirhosseini, Hossein id: '71051' last_name: Mirhosseini orcid: 0000-0001-6179-1545 - first_name: Minghao full_name: Yu, Minghao last_name: Yu - first_name: Xinliang full_name: Feng, Xinliang last_name: Feng citation: ama: Wang X, Kormath Madam Raghupathy R, Querebillo CJ, et al.
