![]() Moreover, the Co-HsGDY based rechargeable zinc–air battery displays an outstanding performance with a power density as high as 209.5 mW cm −2 and superior long-term stability. The Co-HsGDY exhibits an ORR catalytic activity comparable to that of Pt/C. Besides, benefitting from the elegant molecular pores of HsGDY, there is enough space for the metal atoms to coordinate with oxygen-containing groups, which further modulates the electronic structure of the central metal. Articles should be submitted using our online submission system. Thanks to the special sp-C in HsGDY, Co atoms can be anchored to the carbon support without the help of N. Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. Make sure that you check your chosen journal’s web pages for specific guidelines too. Herein, we employ hydrogen-substituted graphdiyne (HsGDY) as a carbon substrate to construct a cobalt atom electrocatalyst (Co-HsGDY) for the oxygen reduction reaction (ORR). Launched in 2010, we've hosted programming at hundreds of institutions around the world, bringing the world’s leaders in chemistry, publishing, research, science communication and career development right to your doorstep. Thus, it is limited in constructing diverse efficient single-atom active sites. The American Chemical Society’s premier outreach program. However, since N atoms are generally doped by post-treatments, the content of N is low. ![]() Typically, these metal atoms rely heavily on N atoms to anchor them to the carbon substrate.
