摘要:
Developing new nanomaterials to devise energy storage/conversion systems has long been considered a prime solution to meet the energy requirements of all the mankind for sustainable developments. Challenges arise upon targeting such electrochemical frameworks:
(i) there is little basic electrochemical understanding of nanomaterials, such as the mass diffusion and charge transfer in them;
(ii) the predetermined design of catalysts and electrodes is urgently needed;
(iii)cost-effectiveness with desirable performance remains challenging in developing most of these devices, particularly fuel cells.
Here, I will talk about our recent advances in formulating low-cost electrocatalysts for fuel cells, including nitrogen-doped carbon nanotubes and platinum monolayer electrocatalysts.
Also, I discuss the structure-property interdependence of as-developed electrocatalysts in the oxygen reduction reaction. Combining the rational development and unique properties of new nanostructures with the requirements for harnessing energy in the future, I show that region-specified modification and long-distance-order assemble of nanostructures into functional nanocomposites promise designing/devising fuel cells, supercapacitors, and batteries, etc.
