英文摘要: Atomic layer deposition (ALD) thin film coating was applied to improve the hydrophilia of biochar derived from black willow. 2 (2Al, 0.82 wt% Al2O3), 5 (5Al, 1.40 wt% Al2O3), and 10 (10Al, 2.36 wt% Al2O3) cycles of alumina ALD were applied. The biochars were characterized by inductively coupled plasma–atomic emission spectroscopy, nitrogen adsorption and desorption, scanning electron microscopy, and Fourier transform infrared spectroscopy. The adsorbents were utilized for the removal of methylene blue (MB) from an aqueous solution to evaluate their adsorption capacities. The 5Al biochar showed the highest adsorption capacity, compared to the uncoated biochar and other Al2O3 coated biochars, due to its...
