Activated interiors of clay nanotubes for agglomeration-tolerant automotive exhaust remediation
Original language description
Naturally occurring clay nanotubes, halloysite (Al2Si2O5(OH)(4)center dot 2H(2)O), with exterior and interior surfaces, respectively, composed of SiOx and AlOx layers, act as an agglomeration-tolerant exhaust catalyst when copper-nickel alloy nanoparticles (Cu-Ni NPs, 2-3 nm) are immobilized at the AlOx interior. Co-reduction of Cu2+ and Ni2+ (respectively derived from CuCl2 and NiCl2) in the presence of sodium citrate (Na3C6H5O7 center dot 2H(2)O) and halloysite yielded the required nanocomposite, Cu-Ni@halloysite. Cu-Ni@halloysite efficiently catalyzes the purification of simulated motor vehicle exhaust comprising nitrogen monoxide (NO) and carbon monoxide (CO) near the activation temperature of Pt-based exhaust catalysts, {= 400 degrees C, showing its potential as an alternative to Pt-based catalysts. In contrast, a different halloysite nanocomposite with the SiOx exterior decorated with Cu-Ni NPs, Cu-Ni/halloysite, is poorly active even at >400 degrees C because of particle agglome
