Abstract

<abstract abstract-type="graphical" xml:lang="en" id="crat201300396-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>In this work, we prepared for the first time a class of novel heterojunctions of BiOBr–BiVO₄ fabricated by depositing BiOBr nanoflakes onto the surface of BiVO₄. The optimum photocatalytic activity of the 0.925BiOBr–0.075BiVO₄ heterojunction was almost 14 and 144 times as high as those of individual BiOBr and BiVO₄ in visible‐light degradation of methylene blue. Photogenerated holes of BiVO4 would play a dominant role in the photocatalytic system. <boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgh2sx3kj2t" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
