| 1 | Unlocking the door to highly efficient Ag-based nanoparticles catalysts for NaBH4-assisted nitrophenol reduction显示文摘Ag-based nano particles(NPs)catalysts have recently attracted in creasi ng atte ntion in NaBH4-assisted n itrophe nol reducti on,especially in 4?n itrophe nol(4?NP)reducti on.Moreover,Ag-based NPs catalysts are con sidered to be very promising for practical applicati ons because of their fascinating advantages,e.g.,easy preparation,relatively low cost and less toxicity,high activity and good stability.Basically,the size and shape of Ag NPs are well known as the key factors for achieving highly efficient catalytic reduction of 4-NP.In this review,three highly efficient Ag-based NPs catalysts(supported Ag NPs,anisotropic Ag NPs and bimetallic Ag NPs)are highlighted for the 4-NP reduction,in eluding the catalytic mecha nism and reactio n rate caused by their adjustments in size and shape.Although high catalytic activity has bee n demonstrated by several Ag-based NPs catalysts,further improvement in the catalytic performance is still desired.In terms of the most recent progress in Ag-based NPs catalysts for 4?NP reduction,this review provides a comprehensive assessment on the material selection,synthesis and catalytic characterizations of these catalysts.Moreover,this review aims to correlate the catalytic performance of Ag-based NPs catalysts with their size and shape,guiding the development of novel cost-effective and high-performance catalysts. | Guangfu Liao Yan Gong Liu Zhong Jiasheng Fang Li Zhang Zushun Xu Haiyang Gao Baizeng Fang | 2019 | Nano Research2019，12，10： | 9 |
