Ternary Ni–Co–Fe oxides based on Prussian blue analog for efficient photothermal catalytic CO2 reduction to CO and CH4

Prussian blue analogue-derived hollow metal oxide heterostructure for high-performance supercapacitors

“…26 Upon further analysis of the peak positions for four elements, it was observed that the peak positions of the same elements exhibit a slight shift. This results from the intimate interfacial interaction between CuO and NiO in the CuO/NiO/Co 3 O 4 heterostructure, [27][28][29] which is consistent with HRTEM data. In summary, the preparation process of the ternary composite CuO/NiO/Co 3 O 4 with a hollow heterostructure is shown in Fig.…”

Prussian blue analogue-derived materials for photocatalysis

“…In 2023, Fang, Zhu and Li prepared an Ni–Fe–Co-based metal oxide (NCF–TMO) using Ni–Fe–Co PBA as the precursor at 400 °C. 136 NCF–TMO was formed by NiO, Co 3 O 4 , and Fe 2 O 3 and achieved a high reaction rate (in system II) in the reduction of CO 2 to CO (2.9 mmol g −1 h −1 ) and CH 4 (1.6 mmol g −1 h −1 ). The mechanism analysis suggested that NCF–TMO has an efficient e–h separation ability under photothermal stimulation.…”
