From harmful Microcystis blooms to multi-functional core-double-shell microsphere bio-hydrochar materials.

ABSTRACT: Harmful algal blooms (HABs) induced by eutrophication is becoming a serious global environmental problem affecting public health and aquatic ecological sustainability. A novel strategy for the utilization of biomass from HABs was developed by converting the algae cells into hollow mesoporous bio-hydrochar microspheres via hydrothermal carbonization method. The hollow microspheres were used as microreactors and carriers for constructing CaO₂ core-mesoporous shell-CaO₂ shell microspheres (OCRMs). The CaO₂ shells could quickly increase dissolved oxygen to extremely anaerobic water in the initial 40 min until the CaO₂ shells were consumed. The mesoporous shells continued to act as regulators restricting the release of oxygen from CaO₂ core
