平均直径约为 2 nm 的金纳米颗粒 (NP) 可以通过固体研磨方法，使用挥发性乙酰丙酮二甲酯，然后用 H-2 还原，直接沉积在生物聚合物纤维素上。纤维素上的金纳米粒子在 60 摄氏度和 pH 9.5 下对葡萄糖有氧氧化产生葡萄糖酸钠表现出相当高的催化活性，周转频率 (TOF) 为 11 s(-1)。只要 Au 颗粒的尺寸相似，Au/纤维素的催化活性与 Au/C 相当。 (C) 2010 Elsevier B.V. 保留所有权利。
Gold nanoparticles (NPs) with mean diameters of around 2 nm could be deposited directly onto a biopolymer, cellulose, by the solid grinding method with volatile dimethyl Au(III)acetylacetonate followed by the reduction with H-2. Gold NPs on cellulose showed appreciably high catalytic activity with a turnover frequency (TOF) of 11 s(-1) for the aerobic oxidation of glucose to produce sodium gluconate at 60 degrees C and at pH 9.5. The catalytic activity of Au/cellulose was comparable to that of Au/C provided the size of the Au particles was similar. (C) 2010 Elsevier B.V. All rights reserved.
