However, the ultimate potential of these nanocrystals is limited by their surface heterogeneity. This review delves into the intricacies of surface heterogeneity, examining its role in dictating the sites for atom deposition and thereby the growth pattern of metal nanocrystals during colloidal synthesis. We also highlight the critical role of surface diffusion in preserving or overriding the impacts of surface heterogeneity, alongside the dynamic nature of surface structure throughout nanocrystal growth. Understanding and controlling the surface heterogeneity of nanocrystals are essential to the development of advanced catalytic materials.","PeriodicalId":48544,"journal":{"name":"Trends in Chemistry","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135274344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, many essential material design challenges remain open for researchers to address. The dispersed nature of the large, rapidly growing body of hybrid perovskite materials data poses a barrier to systematic discovery efforts, which can be solved by materials property databases, either by high-throughput or by systematic, accurate human-curated efforts. This opinioned review article discusses the necessity, challenges, and requirements of building such data libraries. In light of using machine learning (ML) and related tools to solve specific problems, the importance of information related to different material attributes and properties is also highlighted.","PeriodicalId":48544,"journal":{"name":"Trends in Chemistry","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135274971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Direct dehydrogenation of propane (DDHP) offers high propylene selectivity but is limited by quick deactivation due to coke formation. CO2-assisted oxidative dehydrogenation of propane (CO2-ODHP) can consume CO2 and meanwhile reduce coke deposition via the reverse Boudouard reaction. In the current review, direct and CO2-assisted dehydrogenation of propane has been compared from three aspects: reaction mechanisms, catalyst compositions, and CO2 footprint analysis. As the average CO2 emissions from electricity generation decrease due to the utilization of renewable energy, CO2-ODHP potentially leads to a net-negative CO2 footprint while DDHP cannot.","PeriodicalId":48544,"journal":{"name":"Trends in Chemistry","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135589032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, considering its high reactivity, lignin is difficult to extract without avoiding uncontrolled degradation and condensation, which significantly impedes the upgrading of the extracted lignin into high-valued materials. Deep eutectic solvents (DES), as an emerging solvent choice, have driven innumerable advances in sustainable biorefinery, especially in lignin fractionation and valorization. Due to their property tunability and high lignin solubility, lignin modification with DES is an appealing approach to boost the extracted lignin’s reactivity and compatibility with polymers. This review systematically summarizes the latest progress of DES in lignin modification and further upgrading into functional materials.","PeriodicalId":48544,"journal":{"name":"Trends in Chemistry","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135304772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
