If you are establishing your career as a scientist and seeking the optimal bedrock upon which to actualize your aspirations and goals, rest assured that the ideal foundation lies right before you. Are you an engineer motivated by challenging tasks in micro- and nanofabrication? We are looking for a skilled PhD candidate to develop MOF-incorporated micro-supercapacitors, as a part of MOF-MASS/LithoMOFcap projects, which is funded by DTU Alliance PhD stipend Grant. The overall vision of MOF-MASS project is to foster an interdisciplinary environment that integrates four distinct fields: (i) micro- and nanofabrication, (ii) materials characterization, (iii) organometallic and coordination chemistry, and (iv) sustainable electrochemical energy storage (EES). In this context, you will work in close collaboration with several researchers in an interdisciplinary team.
You will be affiliated with DTU Nanolab, where we conduct cross-disciplinary research and apply micro- and nanotechnology to a wide range of scientific disciplines and applications. The Biomaterial Microsystems group is a highly ambitious group, pursuing research on microfabrication of 3D polymer and carbon structures and devices and their application in sustainable energy, drug delivery, and bioelectrochemistry. In addition, we have established a scientific partnership with the Technical University of Munich (TUM) for an almost identical research project called ‘litoMOFcap.’ This collaboration allows you (as Ph.D.-DTU) and the second student at TUM (Ph.D.-TUM) to work closely together in both projects (‘lithoMOFcap’ and ‘MOF-MASS’). As a part of the project, it is expected that you spend at least 6 months of your Ph.D. at TUM to improve your knowledge and experience on different hydrothermal and electrochemical methods to synthesize rationally designed MOF materials for EES.
Responsibilities and qualifications
Miniaturized electrochemical capacitors, conventionally defined as microsupercapacitors (μSCs), gain increasing attention as potential means for energy storage in implants, sensor platforms or personal electronics requiring power in the order of μW. However, the power and energy density in μSCs is still rather low and the performance rapidly decreases during continuous operation. Metal-Organic Frameworks (MOFs) have proven to be exceptional materials to boost the energy and power density of SCs. These materials are excellent precursors to obtain precisely controllable metal oxides (MO), sulfides, and phosphides, homogeneously distributed in an electrically conducting super-porous carbon matrix through a pyrolysis process.
Besides the type of materials, the overall performance of the SCs is also largely dependent on the morphology and architecture of the electrodes. To meet high-performance indicators of SCs, the electrode materials must possess high accessible surface area, well-defined hierarchical porosity, tailored functionalities, high electrical conductivity, and physical/chemical stability in extreme pH regimes. In this context, the utilization of permeable three-dimensional (3D) micro-architectures incorporated with active materials provides several advantages, including reduced ion diffusion length, enhanced charge-discharge rate capability, increased loading of the active materials within the 3D structure, and increased energy density. The overall aim of the MOF-MASS project is to develop a first-ever, cost-effective, high-performance and long-lasting SC device from MOF-incorporated additive manufacturing-derived 3D MO/carbon nanocomposite electrodes. Therefore, your primary tasks will be:
- Plan and execute experimental research in the DTU Nanolab (PolyFabLab) facilities.
- Establishing different chemical and electrochemical methods for the synthesis of rationally designed MOF systems.
- Determination of optimal MOF/photopolymer composition and pyrolysis conditions to achieve hierarchically porous MOF-derived (multi)MO/carbon electrodes.
- Physicochemical and electrochemical characterization of the developed electrodes.
- Assembling different symmetric and asymmetric SC devices.
- Collaborate with an interdisciplinary research team in a focused scientific effort.
- Contribute as teaching assistant at DTU Nanolab and supervise BSc and MSc student projects.
You must have a two-year master’s degree (120 ECTS points) in micro- or nanoengineering, chemical engineering, material engineering or a similar degree with an academic level equivalent to a two-year master’s degree. You must have hands-on experience in chemical and electrochemical synthesis and methods for characterization of nanomaterials. Preferably, you have worked with micro- and nanofabrication techniques and electrochemical energy storages devices. You are able to interact with researchers in a very interdisciplinary environment. A high-grade average and excellent English language skills are decisive to be considered for the scholarship.
