Cellulose and nanocellulose were used as carriers to prepare composites with antimicrobial and catalytic properties. In this reported study, di‐aldehyde cellulose (DAC) was used as a raw material to prepare silver nanoparticles (AgNPs)/nano‐DAC (DANC) aerogels. The AgNPs/DANC aerogels were loaded with 24.78% nanosilver. The experimental materials were characterised using ultraviolet–visible, X‐ray diffraction, scanning electron microscopy, transmission electron microscopy, X‐ray photoelectron spectroscopy, and Brunauer–Emmett–Teller analysis. The test results showed that the AgNPs loaded on the DANC had particle sizes ranging from 3 to 14 nm, with an average particle size of 5.8 nm. The materials loaded onto the DANC were found to be elemental Ag. The specific surface area of AgNPs/DANC aerogels was 35.40 m 2 /g and the average pore diameter was 19.62 nm.
