Sažetak
Nowadays, the need for clean energy solutions is rapidly growing. Systems of high interest include versatile nanomaterials capable of energy conversions and storage, whether as photocatalysts, battery materials or transport layers in photovoltaic devices. Such materials need to satisfy multiple criteria, depending on their application, while the method of their synthesis needs to be reproducible, low-cost, green and scalable. Here we report on a solid state synthesis of titanium oxide nanoparticles through spark plasma discharge. We obtained primary particles of sizes as low as 10 nm with a mixed phase composition. Microscopy revealed multiple stages of assembly, stemming from coalescence and aggregation to agglomeration of web like structures. All of these result point out to a highly nanoporous material with an increased number of oxygen defects introduced into the structure which will hopefully serve as a superior electron transporting layer for flexible organic solar cells.
