Purified H2 gas (99.99 %, v/v) generated from a hydrogen gas generator (QL-300, Saikesaisi Hydrogen Energy Co., Ltd., China) was bubbled into 2 l distilled water at a rate of 300 ml min−1 for 30 min. Then, the corresponding HRW was rapidly diluted to required saturations (1, 10, 50 %, [v/v]). In our experimental conditions, H2 concentration in freshly prepared HRW determined with a “Dissolved hydrogen portable meter” (Trustlex Co., Led, ENH-1000, Japan) was 0.45 mM, and maintained at a relative constant level in 25 °C for at least 12 h.
