Yet, PEC hydrocarbon production remains elusive due to high catalytic overpotentials and insufficient semiconductor photovoltage. Here we demonstrate ethane and ethylene synthesis by interfacing lead halide perovskite photoabsorbers with suitable copper nanoflower electrocatalysts. The resulting perovskite photocathodes attain a 9.8% Faradaic yield towards C2 hydrocarbon production at 0 V against the reversible hydrogen electrode. The catalyst and perovskite geometric surface areas strongly influence C2 photocathode selectivity, which indicates a role of local current density in product distribution. The thermodynamic limitations of water oxidation are overcome by coupling the photocathodes to Si nanowire photoanodes for glycerol oxidation. These unassisted perovskite–silicon PEC devices attain partial C2 hydrocarbon photocurrent densities of 155 µA cm−2, 200-fold higher than conventional perovskite–BiVO4 artificial leaves for water and CO2 splitting. These insights establish perovskite semiconductors as a versatile platform towards PEC multicarbon synthesis. Hydrocarbon selectivity in photoelectrochemical CO2 reduction has been limited due to a lack of low-overpotential catalysts and high-photovoltage semiconductors. Here Cu nanoflowers are interfaced with perovskite light absorbers for bias-free conversion of CO2 to ethane and ethylene coupled to water or glycerol oxidation.","PeriodicalId":18845,"journal":{"name":"Nature Catalysis","volume":"8 2","pages":"137-146"},"PeriodicalIF":42.8,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41929-025-01292-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143077434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SDLs operate in active learning loops, in which a machine learning algorithm plans experiments that are subsequently executed by increasingly automated (robotic) modules. Here we present our view on emerging SDLs for accelerated discovery and process optimization in heterogeneous catalysis. We argue against the paradigm of full automation and the goal of keeping the human out of the loop. Based on analysis of the involved workflows, we instead conclude that crucial advances will come from establishing fast proxy experiments and re-engineering existing apparatuses and measurement protocols. Industrially relevant use cases will also require humans to be kept in the loop for continuous decision-making. In turn, active learning algorithms will have to be advanced that can flexibly deal with corresponding adaptations of the design space and varying information content and noise in the acquired data. Uses of machine learning and automation are increasing and these techniques are becoming popular in catalysis research. This Perspective discusses how active learning workflows and human intervention should be optimized to ensure the most efficient progress for emerging self-driving laboratories performing heterogeneous catalysis research.","PeriodicalId":18845,"journal":{"name":"Nature Catalysis","volume":"8 1","pages":"13-19"},"PeriodicalIF":42.8,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143055010","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}

However, their practical applications are hindered by irreversible oxidative inactivation due to exogenous H2O2 usage. Here we present an alternative catalytic route in haem peroxygenases that uses O2 and small-molecule reductants such as ascorbic acid and dehydroascorbic acid (DHA) to drive reactions. Our experimental and computational studies indicated that DHAA, the hydrated form of DHA, serves as the key co-substrate that activates oxygen to generate the active oxyferryl haem compound I. We also demonstrate the broad applicability of this O2/reductant-dependent route across various haem peroxygenases, highlighting its biological significance for mono-oxygenase functionality. Importantly, this innovative route avoids the use of H2O2, thereby preventing the risk of irreversible enzyme inactivation. Finally, scaled-up reactions yielded chiral, value-added products with excellent productivity, underscoring the synthetic potential of this developed peroxygenase technology for sustainable chemical transformations. H2O2-dependent haem-peroxygenase-catalysed C–H bond oxyfunctionalization reactions have attracted much attention, but elevated concentrations of H2O2 are detrimental to the enzyme. Now, it is reported that this biocatalyst can operate via an alternative pathway using O2 and small-molecule reductants.","PeriodicalId":18845,"journal":{"name":"Nature Catalysis","volume":"8 1","pages":"20-32"},"PeriodicalIF":42.8,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143050532","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}

Using modified graphitic carbon-based catalysts, which are engineered with optimized active sites and structures, the system solidifies hydrogen peroxide and accelerates urea conversion. Precise control of temperature and urea concentration further enhances catalytic performance. The optimized process achieves near 100% purity in percarbamide precipitation from both human and mammalian urine. The collected percarbamide demonstrates remarkable potential for applications in various domains. This approach establishes a closed-loop system for production, utilization and recovery, offering a scalable solution for large-scale urine treatment with important economic and environmental value. The extraction of urea is an important part of wastewater purification and a potential source of valuable fixed nitrogen.

Here we report a hydrogenative oxidation strategy using water as both a source of H2 and formal oxidant, enabling the direct synthesis of lactams from N-heteroarenes and thereby eliminating the need for additional reductants and oxidants and minimizing waste generation. The reaction can be initiated either under low H2 pressure or with a catalytic amount of H2, leading to the efficient transformation of various N-heteroarenes into lactams in excellent yield thanks to an in situ-generated, piperidine-based, ruthenium pincer complex that balances the hydrogenation and dehydrogenation processes. This study will promote the design of other hydrogenative oxidation reactions using water. Water has been used in organic synthesis as a hydrogen and oxygen source for reductive and oxidative transformations, respectively.
