Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adom201570044-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Cadmium selenide quantum dots (CdSe QDs) have excellent properties such as a bandgap position and visible light absorption in the region required for photoelectrochemical (PEC) hydrogen generation systems. However, the slow reaction rate of holes results in corrosion of the CdSe due to hole accumulation. J.‐H. Jang and co‐workers describe on page 907 how graphene quantum dots can provide inexpensive and efficient hole transfer/extraction pathways to improve the stability of the CdSe‐sensitized PEC systems. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgj22cdn54z" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
