摘要: Upcycling Algal blooms (ABs) from eutrophic waters into H2 and CH4 via anaerobic fermentation (AF) demonstrates a substantially promising opportunity to handle environmental issues and achieve a circular economy. However, it is restricted by bottlenecks such as difficult cell harvesting, low biomass hydrolysis and AF efficiencies. Current strengthening measures for these three steps are independent of each other, resulting in a complex technical regulation process and high overall energy consumption. This work demonstrated a trinity strategy to resolve these three limitations with one integral method based on a versatile Chit@Fe catalyst. First, Chit@Fe acts as an absorbent for ABs harvesting resulting in 99 % of ABs cells harvesting within 5 min. Second, Chit@Fe acts as a thermal conductor for biomass hydrothermal hydrolysis and as an electron conductor for AF, improving biomass intracellular composition release to 2-4 folds together with 30 % more small-molecular organics. Third, Chit@Fe acts as electron conductor, triggering a more intensive direct interspecies electron transfer during AF and improved CH4 yields from 403 to 547 mL/g VS. The work provides a paradigm shift of low carbon ABs disposal in eutrophic waters with extra benefits of bioenergy production.
