Development of efficient molecular devices for overall water splitting has always been a hotspot of research to realize clean and sustainable energy conversion.In the case,long-term durability of molecular devices is a crucial factor to determine their practical application.Here,an efficient composite molecular anode was assembled by immobilization of charge-neutral mononuclear Ru1 complex on COOH-functionalized multiwalled carbon nanotubes (MWCNTsCOOH) sticking on a glassy carbon (GC) electrode (Ru1/MWCNTsCOOH/GC).The prepared hybrid anode showed a low onset overpotential of only 380mV for electrocatalytic water oxidation.Moreover,the anode displayed a steady catalytic current density of 1.25mA/cm2 for more than 5h at the overpotential of 580mV,a high TON of 186000 (5h),a TOF of 10.3 s-1 and a faradic efficiency of 96％,indicating the significant efficiency and extremely durability.The excellent durability of the molecular anode should be attributed to the key charge-neutral catalytic intermediates (Ru1a～d) of the catalytic step and the two long flexible carbon chains of the catalyst.
