1Low temperature microwave-assisted vs conventional pyrolysis of various biomass feedstocks显示文摘A comparison between conventional pyrolysis and a novel developed low-temperature microwave-assisted pyrolysis methodology has been performed for the valorisation of a range of biomass feedstocks including waste residues.Microwave pyrolysis was found to efficiently deliver comparable evolution of bio-gases in the system as compared with conventional pyrolysis at significantly reduced temperatures(120 180 C vs 250 400 C).The gas obtained from microwave-assisted pyrolysis was found to contain CO 2,CH 4 and CO as major components as well as other related chemicals(e.g.acids,aldehydes,alkanes) which were obtained in different proportions depending on the selected feedstock.Peter Shuttleworth Vitaliy Budarin Mark Gronnow James H.Clark Rafael Luque 2012Journal of Natural Gas Chemistry2012,21,3:7
2Carbonaceous residues from biomass gasification as catalysts for biodiesel production显示文摘Tars and alkali ashes from biomass gasification processes currently constitute one of the major problems in biomass valorisation,generating clogging of filters and issues related with the purity of syngas production.To date,these waste residues find no useful applications and they are generally disposed upon generation in the gasification process.A detailed analysis of these residues pointed out the presence of high quantities of Ca(>30 wt%).TG experiments indicated that a treatment under air at moderate temperatures(400-800 C) decomposed the majority of carbon species,while XRD indicated the presence of a crystalline CaO phase.CaO enriched valorized materials turned out to be good heterogeneous catalysts for biodiesel production from vegetable oils,providing moderate to good activities(50%-70% after 12 h) to fatty acid methyl esters in the transesterification of sunflower oil with methanol.Rafael Luque Antonio Pineda Juan C.

12Heterogeneous catalysis under flow for the 21st century fine chemical industry显示文摘Due to metal leaching and poor catalyst stability, the chemical industry's fine chemical and pharmaceutical sectors have been historically reluctant to use supported transition metal catalysts to manufacture fine chemicals and active pharmaceutical ingredients. With the advent of new generation supported metal catalysts and flow chemistry, we argue in this study, this situation is poised to quickly change. Alongside heterogenized metal nanoparticles, both single-site molecular and single-atom catalyst will become ubiquitous. This study offers a critical outlook taking into account both technical and economic aspects.Rosaria Ciriminna Mario Pagliaro Rafael Luque 2021Green Energy & Environment2021,6,2:1
13Understanding Bridging Sites and Accelerating Quantum Efficiency for Photocatalytic CO_(2) Reduction显示文摘We report a novel double-shelled nanoboxes photocatalyst architecture with tailored interfaces that accelerate quantum efficiency for photocatalytic CO_(2) reduction reaction(CO_(2)RR)via Mo–S bridging bonds sites in S_(v)–In_(2)S_(3)@2H–MoTe_(2).The X-ray absorption near-edge structure shows that the formation of S_(v)–In_(2)S_(3)@2H–MoTe_(2) adjusts the coordination environment via interface engineering and forms Mo–S polarized sites at the interface.The interfacial dynamics and catalytic behavior are clearly revealed by ultrafast femtosecond transient absorption,time-resolved,and in situ diffuse reflectance–Infrared Fourier transform spectroscopy.A tunable electronic structure through steric interaction of Mo–S bridging bonds induces a 1.7-fold enhancement in S_(v)–In_(2)S_(3)@2H–MoTe_(2)(5)photogenerated carrier concentration relative to pristine S_(v)–In_(2)S_(3).Benefiting from lower carrier transport activation energy,an internal quantum efficiency of 94.01%at 380 nm was used for photocatalytic CO_(2)RR.This study proposes a new strategy to design photocatalyst through bridging sites to adjust the selectivity of photocatalytic CO_(2)RR.Kangwang Wang Zhuofeng Hu Peifeng Yu Alina M.Balu Kuan Li Longfu Li Lingyong Zeng Chao Zhang Rafael Luque Kai Yan Huixia Luo 2024Nano-Micro Letters2024,16,1:0
14Biomass valorization via electrocatalytic carbon–carbon bond cleavage显示文摘Renewable electrocatalytic upgrading of biomass feedstocks into valuable chemicals is one of the promising strategies to relieve the pressure of traditional energy-based systems.Through electrocatalytic carbon–carbon bond cleavage of high selectivity,various functionalized molecules,such as organic acids,amides,esters,and nitriles,have great potential to be accessed from biomass.However,it has merely received finite concerns and interests in the biorefinery.This review first showcases the research progress on the electrocatalytic conversion of lipid/sugar-and lignin-derived molecules(e.g.,glycerol,mesoerythritol,xylose,glucose,1-phenylethanol,and cyclohexanol)into organic acids via specific carbon–carbon bond scission processes,with focus on disclosing reaction mechanisms,recognizing actual active species,and collecting feasible modification strategies.For the guidance of further extensive studies on biomass valorization,organic transformations via a variety of reactions,including decarboxylation,ring-opening,rearrangement,reductive hydrogenation,and carboxylation,are also disclosed for the construction of similar carbon skeletons/scaffolds.The remaining challenges,prospective applications,and future objectives in terms of biomass conversion are also proposed.This review is expected to provide references to develop renewed electrocatalytic carbon–carbon bond cleavage transformation paths/strategies for biomass upgrading.Keping Wang Zhenyan Guo Min Zhou Ying Yang Lanyun Li Hu Li Rafael Luque Shunmugavel Saravanamurugan 2024Journal of Energy Chemistry2024,91,4:0
