Smart Nanoarray Electrodes for Energy Storage and Electrolysis of Water
Hong Jin Fan
School of Physical and Mathematical Sciences, Nanyang Technological University, Singapore.
Nanoarray electrodes are particularly investigated for power source in microelectronics, which requires high rates, high areal capacity/capacitance and long cycle stability. Metal oxides, nitrides and carbides and their hybrids are being widely studied as electrode materials for batteries, supercapacitors, and electrocatalysts. Our group has been actively working on core-shell or core-branch nanoarray materials directly on conductive substrates as electrodes for these devices. In this talk, I will first introduce our smartly designed array electrodes for Li-ion and Na-ion storage, and elaboration on the contribution of extrinsic pseudocapacitance contribution in 2D nanosheets materials. Surface engineering and functionalization strategies, including atomic layer deposition (ALD), graphene quantum dots (GQDs), will be mentioned for performance enhancement. Second, I will briefly discuss the TiC nanomaterial as a highly robust and ultrafast supercapacitor electrode. Finally, I will discuss the RF plasma as a highly effective technique for conversion reaction and surface functionalization of metal nitrides for both HER and OER processes.
