Despite the efforts to enhance product yield with different catalysts, most studies focused on improving efficiency with less emphasis on the selectivity of higher hydrocarbon (C₂₊) products. Hence, CO, CH₄, and HCOOH are the commonly obtained products during CO₂ photoreduction according to most literature. C₂₊ hydrocarbons have a higher market value compared to C₁ products. Therefore, research on photocatalytic CO₂-to-C₂₊ conversion has received significant attention in recent years. This review discusses the progress of CO₂-to-C₂₊ photoconversions. First, the insights into CO₂ reduction, kinetics, critical challenges, and underlying mechanisms involved in the conversion of CO₂-to-C₂₊ are highlighted. Further, the progress on strategies such as defect engineering, heteroatom doping, cocatalysts deposition, single or dual-atom catalysts, heterostructured combinations, and morphological modulations to improve the selectivity of CO₂ reduction towards C₂₊ formation has been discussed. Factors affecting the performance of CO₂-to-C₂₊ are discussed throughout, focusing on aspects like the interaction of reactants with the catalyst surface, various reaction conditions, intermediate formation, *C₁ stabilization, and C–C coupling. Finally, a summary and outlook on recent trends in CO₂ utilization are discussed.</p></div>","PeriodicalId":307,"journal":{"name":"EnergyChem","volume":"6 5","pages":"Article 100130"},"PeriodicalIF":22.2,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141713616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many techniques have been developed to optimize the morphology throughout fabrication extending from thermal and solvent vapor annealing to incorporation of solvent additives. Nevertheless, these posttreatments are unsuitable for large-area OSC fabrication, and solvent additives remain within the active layer, gradually comprising morphology and device performance over time. Recently, the development of solid additives with their unique characteristics, offers superior morphology control, easy posttreatments, and enhanced device stability. Consequently, solid additives have rapidly achieved popularity as a universal and considerably used method to optimize morphology and performance. However, the operational mechanism of solid additives, especially their interactions with donor-acceptor within the active layer remains unclear, hindering their development and use in emerging OSC systems. Therefore, we have summarized recent findings on solid additives volatile and nonvolatile depending on their characteristics, and a comprehensive discussion of different mechanisms is reviewed. These insights aim to assist in choosing suitable solid additives for newly developed OSC systems. Finally, we provide a brief overview of challenges and potential advancements concerning solid additives in OSCs.</p></div>","PeriodicalId":307,"journal":{"name":"EnergyChem","volume":"6 4","pages":"Article 100129"},"PeriodicalIF":22.2,"publicationDate":"2024-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141413426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Iron oxides usually present as hematite (α-Fe₂O₃), maghemite (γ-Fe₂O₃), and magnetite (Fe₃O₄), where the coordination environments of Fe and O vary considerably. The diversity structures of iron oxides, in terms of chemical composition, particle size/shape, and crystal-phase, favor a flexible mediation on the geometric and electronic characters of surface Fe and O atoms that are intimately linked to the active sites for catalysis. Tuning the crystal-phase of size/shape-specified FeO_x particles alters the arrangements of Fe and O atoms both in the bulk and on the surface. While tailoring the particle shape, in a specific crystal-phase, enables to expose the more reactive facets featured by unique arrangements of Fe and O atoms. All these strategies could maximize the number of active sites for catalysis and regulate the adsorption and activation manner of reacting molecules. In addition, the shape and crystal-phase of FeO_x particles, when they are used to support the catalytically more active precious metals, affect the dispersion of the precious-metals via interfacial bonding and charge transfer. In this context, the precious-metals would show distinct electronic features via interaction with iron oxides, while their interfacial bonding is governed by the surface properties of iron oxides. Among them, precious-metal single-atoms, anchored on iron oxides, are characterized by the isolated sites, but a straightforward correlation between their electronic and geometric structures and the catalytic properties is controversial. Alternatively, inverse structures (iron-oxide layers on precious -metal particles) and core-shell geometries (a precious-metal core and an oxide shell) enable to construct active interfaces and describe the geometric and electronic characters. Moreover, the dynamic behavior of precious-metal-support interfaces, under reactive gases and at high temperatures, would provide accurate and realistic evidences for revealing the intrinsic structure-reactivity relationships.</p></div>","PeriodicalId":307,"journal":{"name":"EnergyChem","volume":"6 4","pages":"Article 100124"},"PeriodicalIF":25.1,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141141470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among all types of solid-state electrolytes (SSEs), garnet-based solid electrolytes are one of the most promising candidates which developed due to their relatively high ionic conductivity (10^–4 to 10^–3 mS cm^–1), wide electrochemical stability window (0–6 V vs. Li⁺/Li), and, most importantly, thermodynamic stability with lithium. Applying suitable interfacial engineering solutions is crucial for solid-state lithium metal batteries, especially for garnet-solid electrolytes due to their brittle nature, which cannot withstand high stack pressure. In this review, we focus on the recent developments in interface engineering solutions and broadly classify them based on the interface modification approach/fabrication routes using various classes of materials. Certain vital electrochemical performance parameters have been compared closely, which gives an appropriate estimation of what types of interlayers will be suitable along with the possible mechanistic route. Moreover, the role of lithium affinity at the interface in terms of lithiophilicity and its importance, along with the presence of lithiophobic phases, is discussed as it amplifies the critical current density of the anode/solid-electrolyte interface and reduces the area-specific resistance.
