Microwave quasi-solid-state-constructed low-content Pt on CeO2 with strong electronic interactions for efficient electrocatalytic acidic overall water splitting

Pt-loaded CeO 2 cubes were designed via a rapid and eco-friendly ultrafast microwave quasi-solid-state approach within 60 s, which exhibited a low overpotential of 10 mV to reach 10 mA cm −2 in 0.5 M H 2 SO 4 with excellent long-term stability.
