摘要 Research on water-splitting electrocatalysts is crucial to establishing a solution to the energy crisis.Herein,we report a facile bottom-up strategy for the preparation of high performance supported electrocatalysts for overall water-splitting reaction via a rationally designed defect covalent triazine frameworks(CTFs)support.Specifically,defect CTFs are obtained via binary-precursor polymerization,followed by loading Ru nanoparticles(Ru/D-CTFs-900)with high HER performance at a current density of 10 mA cm-2.The overpotential is only 17 mV.Calcination of the resultant Ru–RuO2/D-CTFs-300 in air,produces excellent OER performance with 190 mV overpotential(at 10 mA cm-2).Furthermore,overall water splitting measurements reveal the potential of 1.47 V,which is better than the majority of the reported Ru-based catalysts.Moreover,density functional theory calculation results show that excellent electrocatalytic properties are attributed to the synergistic effect of Ru nanoparticles and carbon support.
