Through a critical examination of “bottom-up” and “top-down” strategies for converting bio-feedstocks sourced from anthropogenic activities into renewable fuels, the work underscores the need for innovation in catalysts and process intensification. By highlighting the advances and challenges in harnessing unconventional feedstocks and integrating renewable energy, this work points to a future where biofuels stand as a cornerstone of a sustainable energy landscape. The significance of this discussion extends beyond the technical realm, offering a vision for a circular economy that reduces dependence on fossil fuels, addresses climate change, and promotes global energy security. It calls for a united front among researchers, industry leaders, and policymakers to drive the biofuel sector toward efficiency, scalability, and widespread adoption.","PeriodicalId":53121,"journal":{"name":"Chem Catalysis","volume":null,"pages":null},"PeriodicalIF":9.4,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140817461","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}

However, the majority of reported Cu-based catalysts lack a comparison with commercial Cu-based catalysts employed in methanol synthesis from syngas. Furthermore, there are limited research works on the effect of sizes of Cu particle to catalyst performance, especially for inverse Cu catalysts, which is a promising catalyst with highly active ZrOx-Cu interface. By precisely controlling the synthesis method to regulate the particle size of Cu in Zr-Cu inverse catalysts, we illustrated that the copper surface area plays a predominant role in influencing catalytic activity. Additionally, the presence of highly dispersed ZrOx clusters on the surface of Cu particles not only enhances the space-time yield of methanol but also serves to segregate Cu particles and to inhibit sintering. The unique structure of Zr-Cu inverse catalysts leads to comparable reactivity to the commercial Cu catalysts.","PeriodicalId":53121,"journal":{"name":"Chem Catalysis","volume":null,"pages":null},"PeriodicalIF":9.4,"publicationDate":"2024-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140643095","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}

However, finding an economical, stable, non-toxic nanomaterial catalyst poses a significant challenge. Understanding the catalyst’s active state is vital for optimal performance due to potential structural changes during reactions. Herein, we employ various in situ characterizations to detail δ-FeOOH’s structural evolution during hydrogen activation, identifying its active phase while catalyzing the heterogeneous reduction of CO2 by H2. Using in situ environmental transmission electron microscopy, δ-FeOOH is first dehydrated to α-Fe2O3, then reduced to Fe3O4, and finally to α-Fe. Other in situ characterizations revealed that the active state of the catalyst (Fe-350-H2) is a mixture of Fe3O4 and α-Fe. A detailed investigation into the photocatalytic CO2 reduction using batch, flow, and LED reactors unveiled that the Fe-350-H2 catalyst exhibits superior activity and selectivity in activating the reverse water gas shift reaction compared with similar iron-based catalysts.","PeriodicalId":53121,"journal":{"name":"Chem Catalysis","volume":null,"pages":null},"PeriodicalIF":9.4,"publicationDate":"2024-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140632322","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}

However, recent advancements have led to the development of photocatalysts that can absorb deep-red to near-infrared light. These near-infrared photocatalysts (NIR-PCs) offer distinct advantages over traditional UV-vis photocatalysts, including deeper tissue penetration and reduced interference from competing absorption processes. Herein, we summarize the latest advancements in their molecular design based on three activation mechanisms: one-photon absorption, triplet-triplet annihilation upconversion, and two-photon absorption. This review aims to present not only various organic transformations facilitated by NIR-PCs but also the diverse molecular engineering strategies that have been employed in the design and development of NIR-PCs, particularly focusing on those with exceptional absorption capabilities in the NIR region. Finally, a brief overview of the current challenges and opportunities for future explorations of NIR photocatalysis is presented, underscoring the growing significance of NIR-PCs in advancing the frontiers of photocatalysis.","PeriodicalId":53121,"journal":{"name":"Chem Catalysis","volume":null,"pages":null},"PeriodicalIF":9.4,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140622988","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}
