水分解 （英語： water splitting ）是將 水 分解為 氧氣 和 氫氣 的 化學反應 ： 2 H 2 O → 2 H 2 + O 2. 具效率性和經濟性的 光化學 水分解將是帶動 氫經濟 發展的技術性突破。 目前尚無工業級 純水 分解應用，但兩個子反應（氫氣製造和氧氣製造）相對成熟。 工業上， 海水 或 鹽水 分解主要用於生產 氯氣 ；然而，其製程餘氫約佔全球氫氣供應之5%。 光合作用 亦可進行水分解，但不會產出氫氣。 水分解之逆反應是 氫燃料電池 的基礎。 分類 ： . 環境化學. 燃料. 產氫. 工業氣體.
Water splitting is the chemical reaction in which water is broken down into oxygen and hydrogen: [1] 2 H 2 O → 2 H 2 + O 2. Efficient and economical water splitting would be a technological breakthrough that could underpin a hydrogen economy. A version of water splitting occurs in photosynthesis, but hydrogen is not produced.

Water splitting is a process that enables the production of hydrogen by direct water decomposition in its elements. The energy required to cleave H O H bonds can be supplied by different power sources: electrical (current), thermal (heat), or light (electromagnetic radiation).
2022年11月11日 · Photoelectrochemical (PEC) water splitting is a method that generates hydrogen from water by using solar radiation. Despite the advantages of PEC water splitting, its...
2019年3月1日 · The reaction through which H 2 is produced from water is called “water splitting” (WS). By using solar energy to produce organic fuels through CO 2 reduction, researchers are mimicking more closely the mechanism of photosynthesis, and therefore during the process (called “artificial photosynthesis”) both reactions, the splitting of ...
2020年10月13日 · Electrolytic water splitting to generate hydrogen and oxygen is one of the most promising ways in which to harness intermittent renewable power sources and store the energy these provide as a clean-burning and sustainable fuel.
