Hybrid Ni@ZnO@ZnS-Microalgae for circular economy: A smart route to the efficient integration of solar photocatalytic water decontamination and bioethanol production

Water remediation and development of carbon-neutral fuels are priority objectives of our evermore industrialized society. The answer to these challenges should be simple, sustainable, and inexpensive. Thus, biomimetic-inspired circular and holistic processes combing water remediation and biofuel pro...
