摘要

该项目旨在为可持续能源应用开发多孔材料,即氢储存和生物质转化为可再生燃料。该项目的核心是为非洲的研究人员提供以下方面的培训计划:(i) 利用当地可再生原材料;(ii) 利用先进技术设计和合成用于储能的多孔材料(沸石和金属有机框架(MOFs));(iii) 将可持续的低价值原料转化为可再生燃料。我们发现,在高压下压实 UiO-66 MOF 可提高体积储氢能力,而重力吸收能力不会有任何损失,并通过实验证明了 UiO-66 的动态行为与温度有关,这使我们能够提出 UiO-66 的活化温度为 ≤ 150°C。我们利用共造粒技术制造出了 UiO-66/ 纳米纤维单片,这种分层多孔材料具有更强的可用(即可输送)储氢能力。我们阐明了如何利用天然高岭土作为沸石合成的二氧化硅和氧化铝来源。高岭土衍生的沸石 X 被成功用作麻风树油(来自非食用生物质)酯交换转化为生物柴油的催化剂。我们还制备了多孔复合材料(即碳/UiO-66、有机土/UiO-66 和沸石/碳),并将其成功应用于电化学传感。

Capacity building in porous materials research for sustainable energy applications.

The project aimed to develop porous materials for sustainable energy applications, namely, hydrogen storage, and valorization of biomass to renewable fuels. At the core of the project was a training programme for Africa-based researchers in (i) the exploitation of renewable locally available raw materials; (ii) the use of advanced state-of-the-art techniques for the design and synthesis of porous materials (zeolites and metal-organic frameworks (MOFs)) for energy storage; and (iii) the valorization of sustainable low-value feedstock to renewable fuels. We found that compaction of the UiO-66 MOF at high pressure improves volumetric hydrogen storage capacity without any loss in gravimetric uptake, and experimentally demonstrated the temperature-dependent dynamic behaviour of UiO-66, which allowed us to propose an activation temperature of ≤ 150°C for UiO-66. Co-pelletization was used to fabricate UiO-66/nanofibre monoliths as hierarchical porous materials with enhanced usable (i.e. deliverable) hydrogen storage capacity. We clarified the use of naturally occurring kaolin as a source of silica and alumina species for zeolite synthesis. The kaolin-derived zeolite X was successfully used as a catalyst for the transesterification of Jatropha curcas oil (from non-edible biomass) to biodiesel. We also prepared porous composites (i.e. carbon/UiO-66, organoclay/UiO-66 and zeolite/carbon) that were successfully applied in electrochemical sensing.

期刊介绍: Each Interface Focus themed issue is devoted to a particular subject at the interface of the physical and life sciences. Formed of high-quality articles, they aim to facilitate cross-disciplinary research across this traditional divide by acting as a forum accessible to all. Topics may be newly emerging areas of research or dynamic aspects of more established fields. Organisers of each Interface Focus are strongly encouraged to contextualise the journal within their chosen subject.
