When light falls on the nanotubes, they release energetic charge carriers, which split the water molecules inside them into two reactive components - hydroxide radicals and hydrogen ions.

当阳光照射在纳米管上时，纳米管释放出高能量的载荷子，使得水分子分解为两种活性成分-氢氧自由基和氢离子。

Sodium reacts violently with water to produce hydrogen gas and sodium hydroxide.

钠与水剧烈反应生成氢气和氢氧化钠。

Hydroxide: Any compound with one or more functional groups made up of one atom each of hydrogen and oxygen, Bonded together and acting as the hydroxide anion (OH -).

氢氧化物：包含一个或几个由一个氢原子和一个氧原子组成的官能团的化合物，氢和氧原子键合在一起以氢氧基团或氢氧阴离子(OH -)的形式起作用。

If you zap purified water with electric current, you can split apart a water molecule into a positively charged hydrogen ion and a negatively charged hydroxide ion (oxygen attached to hydrogen).

So anyone looking at this sequence would immediately decide to get their hydrogen from that sodium hydroxide production not from the electrolysis of water.
