si-oh meaning in English
层状硅酸盐中断键外裸露的
Examples
- Ethanol synthesis ; rh - mn catalyst ; active site ; si - oh
乙醇合成铑锰催化剂活性位硅羟基 - ( 3 ) a lot of si - oh existing in the surface of sio2 improved the hydrophilicity of composite membrane
可见, sio _ 2起到改善膜综合性能的重要作用。 - The experimental results show that the surface si - oh bonds infrared intensity of ultrafine silicon dioxide was decreased and thermogravimetric loss was increased by using fourier infrared ( ftir ) spectroscopy and thermogravimetric ( tg ) analyzer
傅立叶红外光谱和热重分析结果表明,改性后的超细二氧化硅颗粒表面的硅羟基吸收峰明显减小。 - Catalyst for ethanol synthesis . the results show that the reactive metals rh and mn are fixed on the catalyst surface by the interaction with si - oh , which can enhance the stability of highly dispersed metals . rh and mn interact with each other to form the acitve site with high ethanol synthesis activity . the surface si - oh was found to be of significance on the preparation of catalyst with high catalytic activity
的性质,结果表明,活性金属铑及锰经浸渍法担载于载体上后即与表面羟基作用使金属固定在氧化硅的表面上,保证了高度分散活性金属的稳定性高度分散中的铑锰相互结合,构成了乙醇合成中的高活性位研究发现表面硅羟基在催化剂制备过程中起着重要作用。 - In order to low the concentration of oh in material , sio2 and sio2 - zro2 gel glasses were fabricated by non - hydrolytic sol - gel ( nhg ) process . the structures of gel glasses were characterized by ir spectra . the concentration of si - oh in sio2 gel glasses fabricated by nhg was estimated and lower than that by hydrolytic sol - gel
材料中的残余羚基( oh )可强烈碎灭近红外发光,为有效降低材料中的羚基含量,采用无水瘩胶一凝胶工艺制备了5102 、 5102一zro :凝胶玻璃,用红外光谱对其结构进行了表征,并且估算了510 :凝胶玻璃中的si一oh含量。
