With the depletion of nonrenewable resources such as oil/coal/gas, more and research studies began to focus on high-value utilization residual biomass resources. Herein, for first time, honeycomb nanoporous microspheres fabricated from renewable cellulose were used a carrier fabricate highly dispersed palladium (Pd) nanocatalyst. Various physicochemical characterizations presented convincing pieces evidence good dispersion Pd clusters with mean diameter 1.6 nm. As carrier, an interconnected structure contributed adhesion particles, their rich hydroxyl groups could fix particles. Importantly, matrix in situ induce formation metallic Pd(0) during calcination without reductant. The cellulose/Pd catalyst was applied Suzuki coupling reaction, which exhibited promising catalytic activity compared commercial Pd/C unsupported homogeneous Pd(OAc)2 catalysts, well stability. resource build materials would be important sustainable chemistry.
