Time‐resolved conductivity measurements reveal that a mild hydrogen treatment at 300 °C for 10 minutes successfully extends the lifetime of carriers by more than two‐fold in bismuth vanadate (BiVO4) photoelectrodes. This enhancement is a result of passivation of deep trap states and/or reduction of their density. Consequently, the AM1.5 photocurrent and onset potential for the hydrogen‐treated BiVO4 are significantly improved. This is reported by Fatwa F. Abdi and co‐workers in article number 1701536.

太阳能水分解：通过轻度氢处理来延长金属氧化物光电电极中的电荷载流子寿命（Adv。Energy Mater。22/2017）
时间分辨的电导率测量表明，在钒酸铋（BiVO 4）光电极中，在300°C的温度下进行10分钟的轻度氢气处理，可以成功地将载流子的寿命延长两倍以上。这种增强是深陷阱态钝化和/或密度降低的结果。因此，经氢气处理的BiVO 4的AM1.5光电流和启动电位得到了显着改善。Fatwa F. Abdi及其同事在文章编号1701536中对此进行了报道。
