Evidence Details

Equipment evidence

Then, the reactant solution was put in a microwave reactor (XH-200A, Beijing XiangHu Science and Technology Development Co.) with the optimized heating program, 700 W (10 s) and 160 W (30 s) alternatively for 19 rounds.

Ultrasonic-method evidence

Ultrasonic-method evidence: source values include 60 mg, 35 mg, 30 min.

Abstract evidence

The electrochemical tests reveal that the catalyst with the saturated CQD exhibits best performance in MOR: the mass and specific activity at forward peak position, the potential close to fuel cell operation and 3600 s of chronoamperometric curve are roughly 2–3 folds of the commercial Pt/C.

Particle-size evidence

Particle-size evidence: source values include 2.7 ± 0.5 nm, 4.5 ± 0.6 nm. Entities: Pt-CQD, Pt-RGO.

Additional source evidence

Additional source evidence: source values include 180 °C, 1.5 h.
