was applied to the photocatalytic hydrogen evolution reaction. Insitu introduction of Ni-Cu could significantly improve the photocatalytic hydrogen evolution performance compared with pure g-C3 N4... for increasing the charge transfer rate. They were also the reasons of more efficient charge separation, which ultimately led to a significant promotion on the photocatalytic hydrogen production reaction. Ni......
from the gas handling system into the reaction chamber. The partial pressures of the gas constituents in the reaction chamber can be analyzed over time with the QMS via a leak valve. The hydrogen... at 800 ℃. No hydrogen desorption is observed at the temperature range from 800 ℃ to 900 ℃, but hydrogen evolution restarts at approximately 670℃ during cooling process. In order to prove the drop......
of the hydrogen desorption capacities of the as-milled (40 h) LaMg11Ni+x Ni (x=100%, 200%) alloys with the reaction time in the temperature range of 553-613 K, from which we can see that the hydrogen desorption reaction is very intensive to temperature. To be specific, increasing hydrogen desorption temperature significantly promotes the hydrogen desorption rate. By comparing Fig. 8(a) with Fig. 8(b......
