报告摘要：
Electrochemical energy storage and conversion is one of the most important systems in the efficient utilization of clean and renewable energy sources and elimination of the environmental and health hazards caused by the excess use of fossil fuels. Thus, the development of efficient electrocatalysts with high activity and durability is of great technological and scientific significance. In this talk, the progress in the development of smart carbon materials based on the carbon nanotubes with 2-3 walls, core-shell and ordered nanoporous structure and nano-structured electrode materials for applications in fuel cells, water electrolysis and supercapacitors will be presented. In particular new results in the development of structurally confined ultrafine NiO NPs (~2.3 nm) supported on graphene via amorphous MnOx, MnOx@NiO electrode materials will be given. MnOx@NiO with MnOx:NiO weight ratio of 1:5 achieves a high capacitance of 966 F g-1 based on total electrode materials and 3222 F g-1 based on active MnOx@NiO materials at discharge current density of 2 A g-1. Remarkably, the materials retain 100% capacitance after 2000 cycles at charge and discharge current density of 10 A g-1. In contrast, durability of ultrafine NiO NPs without MnOx confinement is very poor, lost 94% of the initial capacitance under identical cyclic conditions despite the initial high capacitance of 3696 F g-1. The substantially enhanced capacitance, durability and high rate capacity are contributed to the ultrafine NiO NPs on highly conductive graphene and the extraordinary structural confinement effect of the amorphous MnOx layer on the growth and aggregation of active NiO NPs. The results demonstrate a new way to explore the structural confinement effect in the development of highly efficient and durable ultrafine nanosized materials for pseudo-supercapacitors and other energy conversion and storage applications.
