| 1 | The energy-chemistry nexus: A vision of the future from sustainability perspective显示文摘The changing energy-chemistry nexus is discussed in this perspective paper about the future of sustainable energy and chemical production to identify the priorities and open issues on which focus research and development. Topics discussed regard(i) the new sustainable energy scenario,(ii) the role of energy storage(from smart grids to chemical storage of energy),(iii) the outlooks and role of solar(bio)refineries and solar fuels,(iv) how to integrate bio- and solar-refineries to move to new economy,(v) the role of methanol at the crossover of new energy-chemistry nexus,(vi) the role of chemistry in this new scenario,(vii) the role of nanomaterials for a sustainable energy,(viii) the use of nanocarbons to design advanced energy conversion and storage devices, and(ix) possibilities and routes to exploit solar energy and methane(shale gas). The contribution provides a glimpse of the emerging directions and routes with some elements about their possible role in the future scenario, but does not provide a detailed analysis of the state of the art in these directions. | Salvatore Abate Gabriele Centi Paola Lanzafame Siglinda Perathoner | 2015 | Journal of Energy Chemistry2015，24，5： | 2 |
| 2 | Etherification of HMF to biodiesel additives: The role of NH4+ confinement in Beta zeolites显示文摘The role of NH4^+ ion confinement in the catalytic etherification of HMF(5-hydroxymethylfurfural) with ethanol to biodiesel additives was evidenced by studying the catalytic behavior of NH4^+-Beta zeolites with SiO2/Al2O3 ratios of 25 and 75.In order to affect the strength and distribution of the acidic sites, as well as the mobility of NH4^+ ions in the zeolites cages, a secondary level of porosity was introduced in the NH4^+-Beta, presenting a different stability versus alkaline treatment, by using a thermal or an ultrasound assisted method.By analyzing the catalytic behavior in these two series of samples with respect to the changes in porosity by nonlocal density functional theory, structure by XRD, amount of acid sites by FT-IR and mobility of NH4^+ cations by measurements of reversible NH4^+ exchange capacity, was evidenced a decrease in catalytic performances both in terms of rate of HMF depletion and productivity to the main products, when confinement of the ammonium ions is lost due to the introduction of mesoporosity.The high capability of ammonium ions release, associated to the mono-dentate configuration,and the minor confinement effect inside the zeolite pore system, due to the more opened pores structure of mesoporous zeolites, hinders both the direct etherification of HMF to EMF [5-(ethoxymethyl)furan-2-carbaldehyde] and the parallel reaction pathway via acetalization, favoring the rapid desorption of the HMFDEA [5-(hydroxymethyl)furfural diethyl acetal] product out of the crystal and the consequent inhibition of the consecutive reactions to EMFDEA [5-(ethoxymethyl)furfural diethyl acetal] and EMF. | Paola Lanzafame Georgia Papanikolaou Katia Barbera Gabriele Centi Siglinda Perathoner | 2019 | Journal of Energy Chemistry2019，28，9： | 1 |
| 3 | 变革性催化过程生产可再生燃料:展望和挑战显示文摘利用可再生能源与空气中捕获的CO_(2)合成液体燃料(e-fuels)替代化石燃料,是消除温室气体,应对气候变化所必需的技术.例如,欧盟计划于2050年实现净零排放.e-fuels可以作为化学能载体,克服可再生能源的间歇性和难以储存的不足,并为难以实现电气化的地区供给燃料.e-fuels可作为可持续能源长期储存和远距离运输的载体;同时,与对化石燃料减排所需要进行的基础设施大幅度改造相比,e-fuels节约了经济成本和时间成本.发展新的可持续方法生产e-fuels是加速实现能源转型的关键,这为催化科学提出了新挑战.本视角文章在简要介绍了e-fuels在实现零净排放目标方面的关键作用后,讨论了活性反应催化(电催化、光催化和等离子体催化的统称,三者存在很多共性及相似的问题,为简洁起见,本文聚焦于电催化)和目前应用最多的热催化之间的差异,提出了推动生产e-fuels取得进展的重点不在于扩大实验规模,而很大程度在于转变现有的思路和方法,发展活性反应催化的观点.目前活性反应催化的研究方法是从热催化衍生而来的,为推动合成燃料成为现实,研究人员需要重新思考催化原理,从基本观点和机理研究的角度理解活性反应催化与热催化的不同之处.这是未来催化科学推动可持续合成e-fuels技术发展,加速能源转型所面临的挑战. | Georgia Papanikolaou Gabriele Centi Siglinda Perathoner Paola Lanzafame | 2022 | Chinese Journal of Catalysis2022，43，5： | 0 |
