Otherwise, the CoS₂@N-GN hybrid also presents superior long-term catalytic durability. Moreover, an alkaline water splitting device assembled by CoS₂@N-GN as both anode and cathode can achieve a low cell voltage of 1.53 V at 60◦C with a high faraday efficiency of 100% for overall water splitting. The tremendously enhanced electrochemical behaviors arise from favorable factors including small sized, homogenously dispersed novel CoS₂ nanocrystals and coupling interaction with the underlying conductive nitrogen-doped graphene, which would provide insight into the rational design of transition metal chalcogenides for highly efficient and durable hydrogen and oxygen-involved electrocatalysis.]]> Tue 23 Jul 2019 15:27:22 AEST ]]> Metal-Air Batteries: From Static to Flow System https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:43276 Mon 29 Jan 2024 18:05:32 AEDT ]]> Generation of nanoparticle, atomic-cluster, and single-atom cobalt catalysts from zeolitic imidazole frameworks by spatial isolation and their use in zinc-air batteries https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:36381 2 , which was attributed to the high reactivity and stability of isolated single Co atoms. Our findings open up a new avenue to regulate the metal particle size and catalytic performance of MOF derivatives.]]> Fri 03 Apr 2020 16:59:31 AEDT ]]>
