6 FAQs about [Bangladesh norbornadiene solar energy storage]
Is norbornadiene a molecular energy storage system?
Due to its properties, the molecule pair norbornadiene (NBD) and quadricyclane (QC) appears auspicious concerning its feasibility as MOST energy storage system (see Section 1.2). MOST systems can also be considered as molecular photoswitches; 9 in this context, various systems are known in literature (see Scheme 1).
Are molecular solar thermal systems suitable for energy storage?
Molecular Solar Thermal (MOST) systems are interesting candidates for energy storage in one-photon one-molecule processes. The photoinduced conversion of norbornadiene into its strained valence isomer quadricyclane is particularly promising. Challenges concerning the overall efficiency lead to the search for suitable molecule and catalyst design.
What is energy releasing cycloreversion from QC to NBD?
The stored energy can be released on demand. The energy-releasing cycloreversion from QC to NBD can be initiated by a thermal, catalytic, or electrochemical trigger. The reversibility of the energy storage and release cycles determines the general practicality of a MOST system.
