Amino groups are successfully introduced on the surface of BiOBr nanosheets through a facile ammonia functionalization method. The surface morphology of the modified BiOBr hybrids varies on the concentration of applied ammonia solution. The active {001}-facet-exposed feature of nanosheets is well retained after amino-functionalization. With generation of small Bi₂O₄ nanoparticles on the surface of BiOBr nanosheets, the light adsorption of hybrids gradually shifts to the near infrared range. Compared to pure BiOBr with negligible activity, BOB10 hybrids exhibit superior photocatalytic activity for bacterial inactivation, with 7-log cells reduction in 40 min under LED irradiation. Amino functionalization endows BOB10 hybrids excellent adhesion capability towards surface negatively-charged bacterium Escherichia coli, which can significantly shortened access distance of the predominant •O₂⁻ and h⁺ guaranteeing their inactivation ability on cells membrane, thus leading to remarkable bacterial inactivation performance.

通过简便的氨官能化方法将氨基成功地引入到BiOBr纳米片的表面上。改性的BiOBr杂化体的表面形态随所用氨溶液的浓度而变化。在氨基官能化之后，纳米片的活跃的{001}-面暴露特征得以良好保留。随着一代小Bi ₂ O ₄在BiOBr纳米片表面上的纳米颗粒上，杂化物的光吸收逐渐移至近红外范围。与具有可忽略的活性的纯BiOBr相比，BOB10杂种对细菌的灭活表现出优异的光催化活性，在LED照射下40分钟内细胞减少7对数。氨基官能化赋予BOB10杂种优异的粘附能力朝表面带负电荷的细菌大肠杆菌的主要•Ø可显著缩短访问距离₂ ^-和H ⁺保证在细胞上的膜其失活的能力，从而导致显着的失活细菌性能。
