a Schematic illustration of the synthesis and application of carbon paper (CP)/Ga2O3@high-entropy oxide (HEO). Silver represents Ga; light blue, dark blue, green, purple, and blue-violet collectively represent Mn, Fe, Co, Ni, and Zn; yellow represents O; red represents H. b XRD patterns of CP/Ga2O3@HEO, CP/Ga2O3, CP/HEO, CP and PDF information of Ga2O3 and spinel Ni0.5Zn0.2Co0.3Fe2O4. c SEM images of CP/Ga2O3@HEO and histogram of particle size distribution. d Element line scan results of Ga2O3@HEO particle in Fig. 1e. e TEM image of Ga2O3@HEO particle. f Enlarged TEM image of the box area in Fig. 1e, which exhibits the lattice phase of HEO and the boundary between Ga2O3 and HEO. g, h SAED pattern of the core part and shell part of Ga2O3@HEO, respectively.
