Photoaccelerated Water Dissociation Across One-Atom-Thick Electrodes. [PDF]
Nano Lett, 2022 أظهرت التجارب الحديثة أن تفكك الماء السطحي (⇆H2O H++ OH -) يمكن تسريعه أسيًا بواسطة مجال كهربائي مطبق على أقطاب الجرافين، وهي ظاهرة مرتبطة بتأثير فيينا. هنا نبلغ عن تسارع من حيث الحجم لتفاعل تفكك الماء السطحي تحت إضاءة الضوء المرئي. ويرافق هذه العملية فصل مكاني للبروتونات وأيونات الهيدروكسيد عبر جرافين سميك بذرة واحدة وتعززها مجالات كهربائية قوية بينية.
