Abstract

Zinc/platinum (Zn/Pt) bimetallic micromotors have been developed. They moved based on the reduction of fuel compounds such as bromine, p-benzoquinone, and methanol at the surface of the Pt and the oxidation (dissolution) of Zn that occur simultaneously. The redox potential of Zn2+/Zn is very negative and was advantageous to cause the redox reactions. The motion of the motor and the reactions that occurred on the surface were investigated. With test motors containing Ni, it was revealed that the Zn/Pt motors showed almost unidirectional motion to the Zn side. Toxicity of Zn2+ is relatively lower than that of other metal ions. Also, the motor features the use of mild compounds such as methanol that are not harmful to tissues or organisms as their fuels.

生物燃料中自主移动的双金属微电机

锌/铂(Zn/Pt)双金属微电机得到了发展。他们的移动是基于燃料化合物如溴、对苯醌和甲醇在铂表面的还原以及同时发生的锌的氧化(溶解)。Zn2+/Zn的氧化还原电位极负，有利于氧化还原反应的发生。研究了电机的运动和在表面发生的反应。在含Ni的测试电机中，发现Zn/Pt电机向Zn一侧几乎呈单向运动。Zn2+的毒性相对于其他金属离子较低。此外，该发动机的特点是使用温和的化合物，如甲醇，对组织或生物体无害作为燃料。
