Abstract Single-atom catalysts (SACs) have emerged as a frontier in heterogeneous catalysis due to the well-defined active site structure and maximized metal atom utilization. Nevertheless, robustness of SACs remains critical concern for practical applications. Herein, we report highly active, selective robust Ru SAC which was synthesized by pyrolysis ruthenium acetylacetonate N/C precursors at 900 °C N 2 followed treatment 800 NH 3 . The resultant 1 -N exhibits moderate capability hydrogen activation even excess , enables effective modulation between transimination hydrogenation activity reductive amination aldehydes/ketones towards primary amines. As consequence, it shows superior amine productivity, unrivalled resistance against CO sulfur, unexpectedly high stability under harsh hydrotreating conditions compared most nanocatalysts. This strategy will open an avenue rational design other demanding transformations.

Semiconductor-based photoredox catalysis brings an innovative strategy for sustainable organic transformation (e.g., C-C/C-X bond formation), via radical coupling under mild conditions. However, since semiconductors interact with photogenerated radicals unselectively, the precise control of selectivity such synthesis by steering conversion is extremely challenging. Here, judicious design a structurally well-defined and atomically dispersed cocatalyst over semiconductor quantum dots, we demonstrate switch on high-performance selective heterogeneous photosynthesis C-C or C-N along hydrogen production Ni-oxo cluster single Pd atom-decorated CdS dots crafted onto SiO2 support. Mechanistic studies unveil that Ph(•CH)NH2 PhCH2NH2•+ act as dominant intermediates divergent coupled vicinal diamines imines, respectively enabled clusters assisted radical-radical atom-assisted addition-elimination. This work overcomes pervasive difficulties regulation in semiconductor-based photochemical synthesis, highlighting vista utilizing cocatalysts active sites to maneuver unselective engineering toward photosynthesis.
