Polycondensation as a Universal Method for Preparing High-density Single-atom Catalyst Libraries

Paul Joseph Dyson, Mounir Driss Mensi, Pascal Miéville, Laura Piveteau, Xunhui Wang, Xinbang Wu, Daniel Ortiz Trujillo, Miyeon Chang, Ariana Serban, Timo Markus Oskar Felder

Single-atom catalysts (SACs) present a promising subclass of classic heterogeneous catalysts by maximizing metal dispersion and enhancing efficiency. Although high-density SACs (HD-SACs) are reported, their synthesis is typically constrained to specific me ...

Tandem catalysis enables chlorine-containing waste as chlorination reagents

Paul Joseph Dyson, Mingyang Liu, Xinbang Wu

Chlorinated compounds are ubiquitous. However, accumulation of chlorine-containing waste has a negative impact on human health and the environment due to the inapplicability of common disposal methods, such as landfill and incineration. Here we report a su ...

Thermally stable high-loading single Cu sites on ZSM-5 for selective catalytic oxidation of NH3

Paul Joseph Dyson, Xinbang Wu

Rigorous comparisons between single site- and nanoparticle (NP)-dispersed catalysts featuring the same composition, in terms of activity, selectivity, and reaction mechanism, are limited. This limitation is partly due to the tendency of single metal atoms ...

Versatile palladium-catalyzed double carbonylation of aryl bromides

Paul Joseph Dyson, Gabor Laurenczy, Cornel Fink, Xinbang Wu

A versatile palladium-catalyzed double carbonylation of aryl bromides has been developed. Using Pd(OAc)2/BuPAd2 as the catalyst system and DBU as the base, under relatively low CO pressure, various a-ketoamides were produced in good yields. In order to get ...
