Supercapacitors Subject

Another gemstone in the portfolio of rational carbon synthesis is nitrogen-doped carbons. Recently, they became the subject of particular interest to researchers due to their remarkable performance in applications such as C02 sequestration [22], removals of contaminants from gas and liquid phases [23], environmental protection [24], catalysts and catalysts supports [25], or in electrochemistry as supercapacitors [26], cells and batteries to improve stability and the loading capacity of carbon. 

This chapter will cover major topics of CL research, focusing on (i) electrocatalysis of the ORR, (ii) porous electrode theory, (iii) structure and properties of nanoporous composite media, and (iv) modern aspects in understanding CL operation. Porous electrode theory is a classical subject of applied electrochemistry. It is central to all electrochemical energy conversion and storage technologies, including batteries, fuel cell, supercapacitors, electrolyzers, and photoelectrochemi-cal cells, to name a few examples. Discussions will be on generic concepts of porous electrodes and their percolation properties, hierarchical porous structure and flow phenomena, and rationalization of their impact on reaction penetration depth and effectiveness factor.
