“…The XPS survey spectra in Figure A show the presence of Cu, Co, O, N, and C elements in Cu 2 Co 1 and TCPP/Cu 2 Co 1 . The Co 2p spectrum (Figure B) has two main peaks (796.2 and 780.5 eV), which are the spin-orbit peaks of Co 2p 1/2 and Co 2p 3/2 of Co 3 O 4 . , There are two anticonvolution peaks at 780.4 and 782.8 eV in the Co 2p 3/2 range, indicating the Co elements exhibit two oxidation states: Co 3+ and Co 2+ . Similarly, the two anticonvolution peaks at 795.8 and 797.8 eV in the range of Co 2p 1/2 confirm the presence of Co 3+ and Co 2+ .…”

It is desirable to improve the methanol oxidation ability of heterojunction catalysts because of their potential in the field of electrocatalysis. In this article, we have integrated CuO/Co 3 O 4 heterojunction with porphyrin (TCPP) for TCPP/Cu 2 Co 1 . The results demonstrate that the specific surface area and electrochemical active surface area (ECSA) are enhanced, and the unblocked separation and transfer of photogenerated charges are guaranteed by the matched band energy of CuO, Co 3 O 4 , and TCPP. As such, the photocatalytic methanol oxidation reaction (MOR) performance and stability of TCPP/Cu 2 Co 1 are significantly enhanced compared with those of Cu 2 Co 1 . This study provides a promising pathway for the design of MOR catalysts with high MOR activity.

Co3O4/CuO hybrid hollow microspheres have been successfully prepared via thermal decomposition of CoCu glycolates, whose size can be adjusted by varying the molar ratio of Co2+/Cu2+. As lithium‐ion battery (LIB) anode, Co3O4/CuO microspheres exhibited excellent electrochemical performance due to synergistic effects and the hollow structural design, the best Co3O4/CuO sample could maintain a high specific capacity of 1170.4 mAh g‐1 after 300 cycles at 1 A g‐1, and still retain a capacity of 514.5 mAh g‐1 after 1000 cycles at 2 A g‐1. Thus obtained Co3O4/CuO hybrid hollow microspheres hold great potential as anode materials for high‐performance LIBs.
