The stronger Coulomb interaction leads to a stronger water wall at the catalyst/water interface and thus renders the contact between catalytic sites and O2 molecules more difficult, thereby resulting in more sluggish ORR kinetics. The difference in ORR kinetics can reach 10,000-fold between the catalyst with the strong Coulomb interaction and that with the weak Coulomb interaction. Additionally, we reveal an important (yet previously overlooked) prerequisite for a material to be an ORR electrocatalyst comparable to Pt: the atomic charge of catalytic sites should be between −1.0 e and 0.9 e (to circumvent the strong Coulomb interaction). This finding well explains recent experimental results showing that transition metal oxides based on Fe, Y, Ni, Mn, and La have intrinsically limited ORR kinetics (Nat. Catal., 2021, 4, 463–468). The successful explanation further substantiates the plausibility of the finding. Furthermore, we demonstrate that the catalyst–water Coulomb interaction also has a similar effect on the other electrocatalytic reactions consuming small nonpolar molecules, such as the hydrogen oxidation reaction and the nitrogen reduction reaction.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":null,"pages":null},"PeriodicalIF":32.5,"publicationDate":"2024-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141597235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such semitransparent devices can be integrated on the house curtain wall, intelligent windows and plant greenhouse, simultaneous increasing the solar energy collection area and architectural aesthetics. Although the light utilization efficiencies (LUEs) of single-junction devices have exceeded 3.5%, researches about ST-PV devices are still missing an important element – the human to device interaction – as the long-time exposure under the solar irradiation, or even with such semitransparent modules would unfortunately cause photoinduced diseases such as erythema, skin aging, cataracts and even blindness. Herein, we systematically evaluated the photobiological safety of mainstream ST-PV devices, and fabricated a series of high-performance human-friendly ST-PV devices with LUE values exceeding 5.0% and low skin/eye damage levels for human beings. Impressively, such solar cells combine ultraviolet and blue light filtering structures to achieve comprehensive protection against light hazards and record safety working extremum (SWE) values for all-around skin and eye protections.

Here, we introduce an LHCE containing hexafluoroisopropyl methyl ether (HFME) as the diluent to which n-hexane has been added. n-Hexane serves as a kinetic barrier in the “swollen” SEI to suppress the Li corrosion by HFME. A galvanostatically cycled full-cell that includes n-hexane, with an 8-hour rest period inserted at the end of each charge, has a markedly improved calendar life compared to its hexane-free counterpart (80.8% retention after 160 cycles vs. 6.0% retention after 46 cycles).

However, the rapid and uncontrollable crystallization of perovskite poses significant challenges in achieving desired growth orientations and controlling the growth direction during crystallization, necessitating the establishment of optimal substrate conditions. In this study, we propose a bidirectional coordination strategy involving the introduction of cesium trifluoroacetate (CsTFA) onto the tin dioxide (SnO2) surface. Treatment with CsTFA facilitates the passivation of SnO2 vacancies via COOH–Sn while concurrently forming intermolecular interactions with overlying perovskite crystals, manifested as CF3∙∙∙H–N for formamidinium (FA+) and CF3∙∙∙I–Pb, respectively. These interactions initiate the well-established beginning of the perovskite crystals and promotes their vertical growth. Consequently, vertically grown perovskite crystals exhibit reduced tensile strain and fewer crystalline defects. Furthermore, a benign buried interface between perovskite and underlying SnO2, mitigates detrimental damage, thereby suppressing non-radiative recombination losses. This synergetic bidirectional coordination contributes to the fabrication of perovskite solar cells with a maximum power conversion efficiency of 25.60% (certified at 25.39%) and long-term stability under light illumination.","PeriodicalId":72,"journal":{"name":"Energy & Environmental Science","volume":null,"pages":null},"PeriodicalIF":32.5,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141584546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In principle, the 4d and 5d transition metals (TM4d,5d), particularly rhenium (Re), could fabricate desired M-N-C catalysts. However, it is a long-standing challenge to configure Re5d single atom sites with ultra-durable ORR owing to the occurrence of intractable Fenton reactions. In this contribution, we report a Re single-atom catalyst (Re-SAC) featuring a ReN4 configuration that exhibits remarkable ORR activity and stability under alkaline conditions. Specifically, the half-wave potential (E1/2) can reach a maximum of 0.89 V, and no significant changes in E1/2 are observed after 10000 cycles. The zinc-air battery demonstrates superior open-circuit voltage of 1.55 V and exceptional durability, lasting over 300 h at 5 mA cm−2. It was disclosed that incorporating Re into N-C structures effectively modulates the adsorption energy of ORR intermediates, thereby reducing the activation energy of the reaction.
