水泥基硼掺杂石墨相氮化碳降解NO
Cement-based boron-doped graphite phase carbon nitride material degrades NO
摘要
Abstract
Boron doping modification graphite carbon nitride(BCN)was prepared by high temperature calcination of graphite carbon nitride(g-C3N4)and boron oxide(B2O3),and its microstructure,morphology and optical properties were characterized.The mechanical properties and photocatalytic degradation of NO of cement-based materials doped with g-C3N4 and BCN were studied by using porous cement concrete as photocatalyst carrier.The results showed that the introduction of B element increased the specific surface area of g-C3N4 and improved the absorption of visible light.The degradation rate of NO reached 40.7%.When the content reached 6%of cement content,the 7d strength and 28d strength of cement concrete were the best as 8.25MPa and 14.4MPa,respectively.Under visible light conditions,the photocatalytic degradation performance of 7d and 28d were the best,which were 47%and 63%,respectively.关键词
