负载型贵金属离子细菌还原的探索研究傅锦坤于新生林种玉胡荣宗（固体表面物理化学国家重点实验室厦门大学化学系厦门361005）刘月英姚炳新翁绳周（厦门大学生物学系厦门361005）生物化学法制备高分散度贵金属（rH、PT、Pd、Ag、Au）催化剂的研究中...The Gram positive bacteria strain D01 selected From various samples, are possessed of the stronger reducing ability. Its culture was easy. Supported Rh 3+ , Pt 4+ , Pd 2+ , A + g, Au 3+ could be adsorbed and reduced by this bacteria.The results obtained by IR techniques shown that there was the biochemistry action between the bacteria and the noble metal ions. Using the cyclic voltammograph method indicated that the reducing ability of the bacteria were stronger. XPS experiments Further indicated above noble ions could be reduced by this bacteria with diFFerent degree, the reduction did not be inFluenced by the kinds of noble metal ions and supports. The results shown that the properties of redox of above noble metal ions For electron transFer were the same. The preparation of Au catalyst with high dispersion ( Au 0 For nanometer particles ) on (Fe 2O 3)was also studied.国家自然科学基金（风险基金）;固体表面物理化学国家重点实验室基
