title = "Biofilm as a versatile stablizer and promoter for Pd nanoparticle (PdNP) recovery and catalytic denitrification",
abstract = "There is an increasing demand on recycling of palladium from mining waste streams for purposes of resource retrieval and catalytic application. We introduced the novel H2-based membrane biofilm reactor (MBfR) technology to recover Pd in a more sustainable and economic way. The biotic system successfully recovered almost 100% soluble Pd(II) through reductive immobilization under neutral or acidic pH. Compared to an identically established system but without inoculation, the biotic MBfR produced smaller-size nanoparticulate Pd(0), exhibited higher capacity of Pd recovery capacity, lower vulnerability of Pd(0) leaching under higher loadings, and faster denitrification due to the synergetic enzymatic and catalytic processes. Overall, our study gives a promising example of combined Pd recovery and Pd-based catalysis in a single MBfR system for the future application to the practical treatment of the real mining waste streams.",
