photoreduction(光還原) 是指物質在光的作用下獲得電子,從而發生還原反應的化學過程。該術語由“photo”(光)和“reduction”(還原)組合而成,核心在于光能驅動電子轉移,使目标物質(如金屬離子或有機分子)的氧化态降低。

“Photoreduction”是一個複合詞,其含義根據應用領域不同有所差異,以下是詳細解釋:
指在光的作用下發生的還原反應,即物質通過吸收光能實現電子增益或氧化态降低的過程。常見于光催化、光合作用等場景。
示例:二氧化钛在紫外光照射下引發有機污染物的光緻還原分解。
指通過光學手段将圖像按比例縮小的工藝,即“照相縮版”技術。
示例:舊式印刷中常用photoreduction制作微型電路闆模闆。
