The interface between transition metal and metal carbonate exhibits a dynamic equilibrium during the CO2 hydrogenation reaction, involving surface carbonate hydrogenation and CO2 chemisorption. Nonetheless, there have been few reports on engineering the activity of the interface between transition metal and alkaline earth metal carbonate for catalytic CO2 conversion. This work demonstrated that the incorporation of CaH2 in Ni/CaCO3 enhances the CO2 methanation activity of the catalysts. The CO2 conversion for Ni/CaH2-CaCO3 reached 68.5% at 400 °C, which was much higher than that of the Ni/CaCO3 (31.6%) and Ni/CaH2-CaO (42.4%) catalysts. Furthermore, the Ni/CaH2-CaCO3 catalysts remained stable during the stability test for 24 h at 400 °C and 8 bar. Our research revealed that CaH2 played a crucial role in promoting the activity of the Ni-carbonate interface for CO2 methanation. CaH2 could modify the electronic structure of Ni and tune the structural properties of CaCO3 to generate medium basic sites (OH groups), which are favorable for the activation of H2 and CO2. In-situ Fourier transform infrared spectroscopy (FTIR) analysis combined with density functional theory calculations demonstrated that CO2 activation occurs at the hydroxyl group (OH) on the CaH2-modified Ni-carbonate surface, leading to the formation of CO3H* species. Furthermore, our study has confirmed that CO2 methanation over the Ni/CaH2-CaCO3 catalysts proceeds via the formate pathway.</div></div>","PeriodicalId":15728,"journal":{"name":"Journal of Energy Chemistry","volume":"100 ","pages":"Pages 522-532"},"PeriodicalIF":13.1,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142328163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At present, stability is the major technical encounters that hinders its further commercial development. Micro-strain in PSCs is currently a significant factor responsible for the device’s instability. Strain-induced ion migration is widely believed to accelerate perovskite degradation even when external stimuli are excluded. Undoubtedly, it is imperative to study strain to enhance the stability of PSCs. This paper reviews recent developments to understand strain’s origin and effect mechanisms on performance of PSCs, including ion migration, failure behavior, defect formation, and its effect on photoelectric properties, stability, and reliability. Additionally, several well-known strain management strategies are systematically introduced based on the strain effect mechanism and strain engineering on the film, providing more clues for further preparation with increased stability. The manipulation of external physical strain applied from films to entire devices has been extensively studied. Furthermore, recommendations for future research directions and chemical approaches have been provided. It is emphasized that strain engineering plays a crucial role in improving the efficiency and longevity of PSCs. Tensile strain causes rapid degradation, while moderate compressive strain and external strain control could improve properties and stability. Efforts should focus on controlling compressive strain to mitigate residual tensile strain and introducing it in a controlled manner.
