Evidence Details
Activation-energy evidence: source values include 34.95 kJ/mol, 12H, 95.17%, 98.4%.
Equipment-detail evidence: source values include 25 kHz, 500 W, 1.5 h. Entities: XH-2008D.
Energy-comparison evidence: source values include 12H, 120-200 °C. Entities: N-ethylcarbazole, dodecahydro-N-ethylcarbazole.
In the process of Ru/LDH-xCNT catalysts preparation, an XH-2008D ultrasonic instrument was used, which was produced by Beijing Xianghu Technology Development Co., ltd., with an ultrasonic frequency of 25 kHz and a probe diameter of 18 mm.
LDH-xCNT (0.2 g) was dispersed in 20 mL deionized water, and 10.42 mL 0.01 mol/L RuCl3 solution was added according to the theoretical loading of Ru of 5 wt%. Then it was treated at a certain ultrasonic power (P: 100 W, 300 W, 500 W) for a period of time (t: 0.5 h, 1 h, 1.5 h), and N2 was continuously introduced to abrogate the interference of dissolved oxyg...
When Ru/LDH-3.9CNT-(300-1) is used as the catalyst, the conversion of NEC is 100 %, the selectivity of 12H-NEC and the hydrogen capacity reach 98.31 % and 5.76 wt% after 24 min of reaction.
Additional source evidence: source values include 80 °C, 120 °C.
Temperature: 120 ℃ / 90 ℃
Average particle size: 1.63 nm
