PMID: 28212020
J Am Chem Soc. 2017 Mar 08;139(9):3513-3521. doi: 10.1021/jacs.6b12850. Epub 2017 Feb 27.

Selective organic transformation under mild conditions constitutes a challenge in green chemistry, especially for alcohol oxidation, which typically requires environmentally unfriendly oxidants. Here, we report a new plasmonic catalyst of Au supported on BiOCl containing oxygen vacancies. It photocatalyzes...

Marine pollution caused by frequent oil spill accidents has already produced catastrophic influence on marine ecological environments. Even though traditional superhydrophobic/superoleophilic surface-coated materials have demonstrated to be effective for oil/water separation, they still suffer from complicated fabrication procedures, mechanical...
