Limited by the availability of materials with suitable properties, research progress in energy conversion and storage has been extremely slow, creating a significant challenge in modern technological developments. The solution to this problem may be found in nanostructures, because the characteristic sizes of them fall in the same range as that of electronic behaviors relevant to energy-related processes, such as charge separation and charge recombination. In this talk, I will present our recent results in designing, synthesizing and characterizing new nanostructures that can be used for efficient energy applications. New understanding of nanowire growth, the creation of a novel two-dimensional nanonet morphology and the power of nanostructures with multiple parts, each purpose-designed to perform a specific function, will be discussed. Our study shows that providing and maintaining an effective charge transport pathway is of paramount importance to realizing high performance nanostructure-based solar water splitting and battery devices.
