摘要: Abstract Three-dimensionally ordered macroporous (3DOM) monoclinic InVO 4 with nanovoid-like skeletons and high surface areas (35–52 m 2 /g) were fabricated using the citric acid-, tartaric acid- or ascorbic acid-assisted polymethyl methacrylate-templating strategy. Photocatalytic activities of 3DOM-structured materials evaluated for degradation methylene blue (MB) under visible-light illumination. Compared to bulk , showed much better visible-light-driven photocatalytic performance MB degradation. It is concluded that excellent activity associated their higher oxygen vacancy density lower bandgap energy as well 3DOM structure. We are sure promising photocatalysts removal organics from wastewater
