Scientists Develop Z-scheme Catalyst For Contaminants In Water In recent years, rapid industrialization has caused increasingly severe environmental pollution. Antibiotics and microbiological contamination in water have become major threats to human health and critical risks to ecosystem security worldwide. Therefore, an effective treatment approach has become an urgent task for elimination of bacterial and antibiotic contamination from the watery environment at present. Recently, a team led by Prof. WU Zhengyan from the Institute of Intelligent Machines of the Hefei Institutes of Physical Science developed a novel Z-scheme photocatalyst to deal with contaminants in water. In a study published in the journal
