Electronic/mass transport increased hollow porous Cu3P/MoP nanospheres with strong electronic interaction for promoting oxygen reduction in Zn-air batteries

Actual pseudocapacity for Li ion storage in tunable core‐shell electrode architectures

“…Meanwhile, that of NFNTO (Figure 2H) were blurred and disordered, along with unclear lattice distortions, suggesting defects in the Ti‐based samples. All these results confirmed that introducing Ti into the sample was accompanied with rich‐defects and strong electronic interactions, which are all the features of ideal good LIB electrode 53–55 …”

Atomically dispersed Co in a cross-channel hierarchical carbon-based electrocatalyst for high-performance oxygen reduction in Zn–air batteries

“…The results indicate that the synergistic effect of the silica and ice templates can optimize the hierarchically porous structure and specific surface area of the catalysts, which may promote the electron/mass transport during the ORR process. 34 X-ray photoelectron spectroscopy (XPS) was adopted to investigate the elemental valence and compositions of the as-prepared catalysts. The survey spectra of CoSA@NPC, NS-NPC and NI-NPC display typical peaks of Co, O, N, and C (Fig.…”

Material design and surface chemistry for advanced rechargeable zinc–air batteries

“…To address these problems, many studies have been conducted to induce an interaction between P and other transition metals or carbon materials. 94,95 Guo et al reported Cu 3 P/MoP nanospheres and conrmed that charge transfer occurred between the metal-phosphide bonds. 95 The fabricated rechargeable ZABs exhibited a high power density of 156 mW cm À2 and high stability for 231 h, greatly outperforming the commercial Pt/C (131 mW cm À2 , 157 h).…”

These superior performances were correlated with the strong interaction between the Cu 3 P and MoP species.…”
