摘要: Abstract In this study, hierarchical porous boron nitride nanosheets (hp-BNNSs) were prepared by pyrolyzing the mixture of acid and urea at 1000 °C for 5 h. The hp-BNNSs exhibited structure with pores in range 1.1 nm–40 nm a higher specific surface area 1145 m2/g. showed versatile adsorption capacity to industrial dyes (methylene blue (MB) rhodamine B (RhB)), heavy metal ions (Cu2+ Ni2+), antibiotic (tetracycline (TC)). capacities MB, RhB, Cu2+, Ni2+, TC 201 mg/g, 385 mg/g, 417 mg/g, 280 mg/g, 263 mg/g, respectively. Besides that, also fast rate as 99 % MB RhB removed from solution within 20 min. Significantly, excellent performance demonstrated its great potential water treatment.
