专利号:US-8314015-B2 优先权日:2010-07-14 标题 :Silicon surface modification for the electrochemical synthesis of silicon particles in suspension 发明人:TU CHANG-CHING; TANG LIANG; VOUTSAS APOSTOLOS T 权利人:TU CHANG-CHING; TANG LIANG; VOUTSAS APOSTOLOS T; SHARP LAB OF AMERICA INC 摘要:A process of silicon (Si) surface modification is provided for the electrochemical synthesis of Si particles in suspension. The process begins with a Si first substrate with a surface, and forms Si particles attached to the surface. Hydrogen-terminated Si particles are created and the first substrate is immersed in a hexane/1-octene (1/1 volume ratio) solution with a catalytic amount of chloroplatinic acid (H 2 PtCl 6 ). 1-octene is bonded with the hydrogen-terminated Si particles, creating modified Si particles, with octane capping ligands, attached to the substrate surface. The first substrate is then exposed to ultrasonication, separating the modified Si particles from the first substrate. After removing the first substrate, a suspension is created of modified Si particles suspended in excess hexane/1-octene.
