China''s rise to global economic leadership has created an increasing reliance on foreign oil and gas, an energy security dilemma leaving the Middle Kingdom vulnerable to global sea lines of communication where 80% of its oil is transported but not secured by its comparatively weak navy (Jiang 2015, para 5).
Nanoporous carbon materials can cover a remarkably wide range of physicochemical properties. They are widely applied in electrochemical energy storage and electrocatalysis. As a matter of fact, all these applications combine a chemical process at the electrode–electrolyte interface with the transport (and possibly the transfer) of electrons.
