Mesoporous Natural Fiber Welded Cellulose Containing Silver Nanoparticles as a Recyclable Heterogeneous Catalyst

Front cover: In article 2300020 by Nathaniel E. Larm, David P. Durkin, and co-workers, composites of non-derivatized mesoporous fiber-welded cotton and embedded silver nanoparticles (AgNPs) serve as heterogeneous catalysts for recyclable 4-nitrophenol reduction by sodium borohydride. Despite being non-derivatized cellulose, the mesoporous nature of the scaffold entraps the nanoparticles and prevents Ag leaching.
