Abstract
The back cover picture shows a photocatalytic remediation of polycyclic aromatic hydrocarbons (PAHs) from wastewater with graphene oxide (GO) enwrapped silver phosphate as visible light‐driven photocatalysts. PAHs are a class of highly mutagenic and carcinogenic organic pollutants that pose serious threats to human health and the ecosystem. GO/Ag3PO4 was synthesized by a simple precipitation method. The photocatalysts exhibited superior photocatalytic activity and stability. The degradation efficiency of naphthalene, phenanthrene and pyrene could reach 49.7%, 100.0% and 77.9%, respectively within 5 min irradiation. Meanwhile, the efficiencies of 44.6%, 95.2% and 83.8% were achieved for naphthalene, phenanthrene and pyrene degradation even after 5 times of recycling in the GO/Ag3PO4‐PAHs photocatalysis system. More details are discussed in the article by Bao et al. on page 1549–1558. image
