For such a sluggish four-hole and four-proton transfer reaction in a long timescale of ms\u2013s, more and more studies have shown that the accumulation of multiple surface-trapped holes (e.g., high-valent iron oxo on hematite surfaces) or &#8220;oxidizing equivalents&#8221; is a prerequisite for efficient PEC water oxidation process. Previous PEC water oxidation studies commonly apply high potentials (&gt;1.2 VRHE) to achieve this key. But how to complete multi-hole transfer under low bias (near the onset potential) remains unknown.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2023-04-boosting-multi-hole-oxidation-catalysis-hematite.html\" target=\"_blank\" rel=\"nofollow noopener\">Boosting multi-hole water oxidation catalysis on hematite photoanodes under low bias<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Photoelectrochemical (PEC) water oxidation reaction has attracted considerable attention in recent years because of its importance in solar energy conversion.
