Bacterial cellulose-assisted hydrothermal synthesis and catalytic performance of La2CuO4 nanofiber for methanol steam reforming

► A novel metathesis route for the synthesis of La2CuO4 was described. ► Shape-Controlled Synthesis of La2CuO4 Nanostructures was investigated. ► The excellent performance of the novel La2CuO4 nanofibers in catalyzing SRM was studied in detail.
