A sieve for molecules

Scientists have long tried to use graphene, which is composed of carbon, as a kind of sieve. But this material doesn’t have any pores. Now, a team has found an alternative material which comes with pores from the outset. Researchers from Bielefeld, Bochum and Yale have succeeded in producing a layer of two-dimensional (2D) silicon…

Efficient removal of Cr(VI) by a 3D Z-scheme TiO2-ZnxCd1-xS graphene

https://doi.org/10.1016/j.jes.2021.09.037Get rights and contentAbstractEfficient and robust photocatalysts for environmental pollutants removal with outstanding stability have great significance. Herein, we report a kind of three dimensional (3D) photocatalyst presented as Z-scheme heterojunction, which combining TiO2 and ZnxCd1-xS with graphene aerogel to contrast TiO2-ZnxCd1-xS graphene aerogel (TSGA, x=0.5) through a moderate hydrothermal process. The as-prepared Z-scheme TSGA…
