The oxygen reduction reaction (ORR) is an important challenge in the development and large-scale distribution of energy conversion devices, especially low-temperature proton exchange membrane (PEM) fuel cells. In order to speed up ORR kinetics improve cell performance, iron-doped calcium titanate (CTFO) proposed as a cocatalyst. Fundamental physical chemical characterizations by means X-ray dif...

The concern about global warming bound to CO2 emissions has shifted the attention of scientific, industrial, and social communities from mere use cheap abundant energy sources exploitation renewable energies expansion relevant transmission network. Within this frame, H2 is progressively assuming role preferred vector thanks i) its abundance, it possible obtain water (photo-)electrolysis; ii) “c...

The focus of microbial fuel cell research in recent years has been on the development materials, microbes, and transfer charges system, resulting a substantial improvement current density improved power generation. cathode is generally recognized as limiting factor due to its high-distance proton transfer, slow oxygen reduction reaction (ORR), expensive materials. heterogeneous determines gener...
