Abstract
Photocorrosion, that causes rapid deactivation of Cu(2)O photocatalysts, was addressed by incorporating this oxide in a composite with reduced graphene oxide which acts as an electron acceptor to extract photogenerated electrons from Cu(2)O. Cu(2)O-rGO composite engineering also allows enhancing significantly photocatalytic activities of Cu(2)O for H(2) generation.
摘要
光腐蚀会导致 Cu(2)O 光催化剂迅速失活，通过将这种氧化物与还原氧化石墨烯复合，可以解决这个问题，还原氧化石墨烯可以作为电子受体从 Cu(2)O 中提取光生电子。Cu(2)O-rGO 复合材料的工程设计还可以显著提高 Cu(2)O 用于 H(2)生成的光催化活性。
