纳米氧化铜的制备及其室温脱除 H2S 的性能研究
Preparation of Nano-CuO and Its Removal Performance of H2 S at Room Temperature
摘要
Abstract
Nano-CuO was prepared by methods of liquid-phase precipitation and solid state reaction. The structure of nano-CuO was analyzed by XRD,XPS,TEM and BET techniques,and the effect of the structure of nano-CuO on the removing performance of H2 S was also studied.The results indicate that various crystal size nano-CuO can be prepared by changing preparation process parameters.The desulfurization performance of nano-CuO decreases significantly with the increases of crystal size.The nano-CuO with the crystal size of 9.3 nm exhibits the best desulfurization performance,and the breakthrough time of H2 S can reach 270 min.A small amount cluster caused by small crystal size has a little impact on the desulfurization activity of nano-CuO.However,the appearance of oxygen vacan-cies on the copper oxide surface and the decrease of electron cloud density around the copper are bene-ficial to the improving of desulfurization performance of nano-CuO.When the specific surface area is a little different,the effect on the desulfurization activity of nano-CuO is not obvious.But the removal of H2 S can be improved when the irregular pore formed by grain accumulation distribution is narrow, and the open and contraction pore structures exist at the same time.关键词
