Evidence Details
Activation-energy evidence: source values include 20 ~ 30 kJ/mol, 20.3 K.
The reaction vessel was sealed and placed in the microwave labstation (XH-800S, Xianghu Beijing, China). The sample was finally heated to 453 K within 15min and held at this temperature for 10min, corresponding pressure at this final temperature was 1.8–1.9 MPa.
The metal particles' size of samples ACPt6, NACPt6, NACPt12 and NACPt20 were approximately 4.6 nm, 2.1 nm, 5.5 nm and 7.3 nm respectively by using Scherrer's equation.
Microwave-method evidence: source values include 453 K, 180 °C, 15 min, 10 min.
Additional source evidence: source values include 0.5 L, 623 K, 3 h, 1 K.
It must be noted that the mean particle sizes for NACPt6 and ACPt6 were 2.27 nm and 4.54 nm respectively, indicating that the N doping process may give rise to much smaller Pt particle size, and hence improve the Pt dispersion.
Particle-size evidence: source values include 2.27 nm, 5.73 nm, 7.25 nm.
Additional source evidence: source values include 3 K, 1096 K, 2 h.
Additional source evidence: source values include 36 g, 28%, 12 g.
Time: 15 min / 10 min / 1 h
the hydrogen storage on Pt doped NAC at 298 K presented much higher enhancement factor of 1.82 compared with the Pt doped AC due to the spillover effect, depending on Pt content.
Additional source evidence: source values include 30 min, 336 K.
Additional source evidence: source values include 593 K, 12 h.
Additional source evidence: source values include 923 K, 1 h.
