As global energy consumption increases, the demand for renewable energy technologies and processes having a less harmful impact on the environment is growing rapidly. Among the numerous efforts deployed to decrease our dependence on fossil fuels, one promising strategy is to power the synthesis of chemicals and fuels from naturally abundant resources and by using renewable electricity. These processes are compatible with green energy sources like hydroelectricity and intermittent renewable energy supplies such as solar- or wind-derived electricity and can enable sustainable production of chemicals and fuels. Accordingly, substantial efforts have been made to store energy in the forms of chemical bonds by developing processes for the (photo)electrochemical conversion of CO2, N2, H2O and biomass to valuable products, such as hydrocarbons and oxygenates, ammonia and hydrogen, and to foster the development of improved energy storage devices. Developing and deploying these technologies will require the application of knowledge, concepts and tools from a variety of fields including materials science, physics, chemistry (electrochemistry) and, most particularly, electrocatalysis and photoelectrocatalysis. This relies on our understanding of the structure-activity-stability relationships of catalytic materials for the targeted reactions. The aim of this proposal is to purchase a unique electrochemical mass spectrometer (EC-MS) capable of quantitative and real-time detection of (photo)electrochemical reaction products. The equipment offers a set of unprecedented capabilities in terms of sensitivity and response time, allowing measurements to be performed on a time scale and with a sensitivity that cannot be reached now. The equipment will be used hands-on by 40 HQP, adding an important component to their training and increasing their employability. It is needed urgently and is critical to the research of all co-applicants. It will greatly expand their research capabilities and raise their ability to build and strengthen their collaborations with academia and industry. It is required for research programs in areas of high socio-economic importance to Canada, e.g. energy conversion and storage (fuel cells, NH3 synthesis, conversion of CO2 into value-added products, hydrogen production, lithium batteries, solar fuels), wastewater treatment and materials sciences. Considering the global importance of these areas, the acquisition of this equipment will propel Canadian research to the forefront of the scientific scene, enabling our researchers to develop accurate mechanistic models, shed light on the processes responsible for their degradation, and ultimately develop materials that are stable in operating conditions and that show better energy efficiency and improved conversion efficiency.

随着全球能源消耗的增加，对可再生能源技术和对环境有害影响较小的过程的需求正在迅速增长。在减少我们对化石燃料的依赖的众多努力中，一种有前途的策略是为化学物质和燃料的合成从自然丰富的资源和使用可再生电力提供动力。这些过程与绿色能源兼容水力发电和间歇性可再生能源供应，例如太阳能或风能的电力，并且可以实现可持续的化学品和燃料的生产。因此，通过开发（照片）二氧化碳，N2，H2O和生物量的电化学转换为有价值的产品（例如碳氢化合物和氧化，氨和氢），以及促进改善储能设备的开发，为二氧化碳，N2，H2O和生物量的电化学转化而开发了（照片）的电化学转换，以将能量存储在化学键的形式中，并促进了改善的储能设备的开发。 开发和部署这些技术将需要从各个领域的知识，概念和工具应用，包括材料科学，物理，化学（电化学），尤其是电催化和光电催化。这依赖于我们对靶向反应的催化材料的结构活性稳定关系的理解。该建议的目的是购买能够对（照片）电化学反应产物进行定量和实时检测的独特电化学质谱仪（EC-MS）。该设备在灵敏度和响应时间方面提供了一组空前的功能，可以在时间尺度上进行测量，并且现在无法达到灵敏度。 设备将通过40 hqp动手操作，为他们的培训增加一个重要的组成部分并提高其就业能力。迫切需要它，对于所有共同申请者的研究至关重要。它将大大扩展他们的研究能力，并提高他们建立和加强与学术界和行业的合作的能力。这是对加拿大具有很高社会经济重要性领域的研究计划所必需的，例如能量转化和存储（燃料电池，NH3合成，将CO2转化为增值产品，氢生产，锂电池，太阳能燃料），废水处理和材料科学。考虑到这些领域的全球重要性，该设备的获取将使加拿大的研究成为科学现场的最前沿，使我们的研究人员能够开发出准确的机械模型，阐明导致其降级的过程，并最终开发在运营条件下稳定的材料，并显示出更好的能量效率和改善的转化效率。
