A team of researchers at the Moscow Institute of Physics and Technology<\/a>, Skoltech<\/a>, and the Russian Academy of Sciences Joint Institute for High Temperatures<\/a> have been researching how defected graphene can affect electron transfer at the graphene-solution interface.<\/p>\n After testing the defected graphene, researchers found that these defects can increase its charge transfer rate. By varying the type of defect, it is possible to selectively catalyse the electron transfer to a certain class of reagents in solution. This can be very useful for creating efficient electrochemical sensors<\/a> and electrocatalysts.<\/p>\n Often used in electrochemistry, scientists have recently based new electrodes on carbon. This new electrode is made of graphene<\/a> and has great potential for facilitating innovation in biosensors, photovoltaics, and electrochemical cells. For example, chemically modified graphene can be used as a cheap and effective analogue of platinum or iridium catalysts in fuel cells and metal-air batteries.<\/p>\n The chemical structure and electronic properties have a significant impact on the kinetics of redox processes. The electrochemical characteristics of graphene have been exploited in recent experiments showing the possibility of accelerating the transfer at structural defects, such as vacancies, graphene edges, impurity heteroatoms, and oxygen-containing functional groups.<\/p>\nThe electrochemical characteristics of graphene<\/h3>\n
