Investigation of LiCo2-xNixO4 for water splitting
A major challenge in this century is to meet the high energy demand with a growing world population. This reinforces the need for a cost effective and efficient catalyst for the bottleneck OER in water splitting. In this report, we investigate the OER activity of spinel type lithium-based transition...

| description | A major challenge in this century is to meet the high energy demand with a growing world population. This reinforces the need for a cost effective and efficient catalyst for the bottleneck OER in water splitting. In this report, we investigate the OER activity of spinel type lithium-based transition metal oxides, LiCo2-xNixO4 (where x = 0, 0.2, 0.4, 0.6, 0.8), synthesised by thermal decomposition method with varying content of nickel and cobalt. Measurements of X-Ray Diffraction (XRD), Brunauer, Emmett and Teller (BET), Thermogravimetric analysis (TGA) and cyclic voltammetry (CV) were taken and used to characterize and investigate the OER performance. Li〖Co〗_1.2 〖Ni〗_0.8 O_4 was determined to be the best performing catalyst with high OER activity and excellent cycling stability. |
