DOI: 10.1016/j.catcom.2018.01.027
Abstract: Abstract Maintaining high dispersion of palladium is critical for Pd-based catalysts, which suffer from deactivation due to sintering at high temperatures (≥800 °C). Here, we report direct evidence that Pd nanoparticles (~4 nm) of a palladium silica… read more here.

DOI: 10.1021/acs.est.2c05282
Abstract: The aggregation-redispersion behavior of nanomaterials determines their transport, transformation, and toxicity, which could be largely influenced by the ubiquitous natural organic matter (NOM). Nonetheless, the interaction mechanisms of two-dimensional (2D) MoS2 and NOM and the… read more here.
