Hydrogen has been identified as the ‘fuel vector’ of the future, as it is perfectly environmentally-friendly, renewable, abundant and has high mass-based energy density. It has increasingly been considered as the best alternative to fossil fuels, and is ultimately expected to provide the solution to transport requirements and large-scale storage of energy. The corresponding technologies have already started emerging even in the consumer sector; Toyota and Honda are introducing hydrogen fuel cell powered cars, hydrogen re-fueling stations have rapidly been built in the USA, Europe and Japan. Hydrogen can be produced by electrolysis of water, which provides a completely clean route to the hydrogen economy without the consumption of fossil fuels or the emission of carbon dioxide, especially if supported by solar-, wind-, or hydro-produced electricity. However, in order to make this technology more cost-competitive, more electroactive, durable and cheaper electrode materials are needed. Further, for applications where a sudden burst of electrical energy is needed (electric and fuel-cell cars, electronic equipment, airplane emergency slides, etc.), electrochemical supercapacitors are best suited. In order to increase the power and energy density of present supercapacitors, better electrode materials are also needed.

氢已被确定为未来的“燃料载体”，因为它是完美的环保，可再生，丰富，并具有高质量的能量密度。它越来越被认为是化石燃料的最佳替代品，并最终有望为运输需求和大规模储能提供解决方案。相应的技术已经开始出现，甚至在消费领域;丰田和本田正在推出氢燃料电池驱动的汽车，氢再加油站已迅速建立在美国，欧洲和日本。氢可以通过电解水来生产，这为氢经济提供了一条完全清洁的途径，而无需消耗化石燃料或排放二氧化碳，特别是在太阳能，风能或水力发电的支持下。然而，为了使该技术更具成本竞争力，需要更电活性、更耐用和更便宜的电极材料。此外，对于需要突然爆发电能的应用（电动和燃料电池汽车、电子设备、飞机紧急滑梯等），电化学超级电容器是最适合的。为了提高现有超级电容器的功率和能量密度，还需要更好的电极材料。
