Direct integration of full-spectrum solar thermal conversion (STC) and high electrocatalytic oxygen evolution activity is achieved by fabricating a hierarchical nanocage architecture composed of graphene-encapsulated CoNi nanoparticle, delivering a near-complete 98 % absorptivity of solar spectrum and a high STC efficiency of 97 %, enabling a remarkable potential decrease of over 240 mV in electrocatalytic oxygen evolution under solar illumination.
