开发了一种环境友好且简便的方法,可以在室温下在水溶液中合成氮化硼纳米片/银纳米颗粒杂化物(BNNS/Ag),无需额外的还原剂。 BNNS 用一薄层单宁酸-铁离子 (TA-Fe) 络合物进行修饰。由于TA的强还原性,在改性BNNS的表面原位形成了直径约为7 nm的均匀银纳米粒子。所得纳米杂化物在4-硝基苯酚还原中表现出优异的催化活性。 BNNS/Au 和 BNNS/Pd 纳米杂化物也可以通过这种方法制备,这意味着其在催化、生物医学和传感领域具有广泛的前景。
An environmentally friendly and facile approach was developed to synthesize boron nitride nanosheet/Ag nanoparticle hybrids (BNNS/Ag) in aqueous solution at room temperature without additional reductants. BNNSs were modified with a thin layer of tannic acid–ferric ion (TA–Fe) complex. Silver nanoparticles with a uniform diameter of approximately 7 nm were in situ formed on the surface of the modified BNNSs due to the strong reducibility of TA. The resultant nanohybrids showed excellent catalytic activity in reduction of 4-nitrophenol. BNNS/Au and BNNS/Pd nanohybrids can also be fabricated by this means, implying its extensive promise in catalytic, bio-medical and sensing fields.
