Abstract A comprehensive understanding of the electronic structure catalytic active centers and their nearby environments is essential for clarifying link activity. This can facilitate design development novel metal‐free carbon‐based materials with desirable properties from industrial lignin waste. In this research, phosphorus (P) or nitrogen (N) atoms are incorporated into sulfur (S)‐doped porous carbon using a highly effective collosol doping carbonization method, which alters configuration sites enhances performance. The P S co‐doped (SPC) demonstrates remarkable effectiveness in oxidation benzyl alcohol (BA), reaching high conversion rate 96.6% within 2 h benzaldehyde (BAD) yield 92.5%, along turnover frequency (TOF) value 8.6 × 10 −3 mol·g −1 ·h . It also exhibits strong selectivity other functionalized alcohols. Density functional theory calculations (DFT) indicate that incorporation N atom S‐doped increases electron density at Fermi level modifies Mulliken charge distributions sites, enhancing cooperative regulation activity, particularly co‐doping structures. These findings offer guidance advanced catalysts.

The development of novel host-guest catalysts with nanoscale active sites provides new opportunities to gain highly efficient catalytic performance for the oxidation aromatic alcohols into high-value compounds. In this work, we develop a green and facile synthesis method incorporate Pd nanoparticles (PdNP) robust hierarchical porous Zr-metal-organic framework (Zr-IPA) through in situ solvent-free wet reduction techniques. optimized PdNP/Zr-IPA catalyst exhibits exceptional benzyl alcohol performance, selectively oxidizing 95.3% benzaldehyde (yield 97.7%) at 70 °C within 12 h. Additionally, demonstrates superior activity various using different oxidants. turnover frequency reaches 82.3 h-1 °C, which is 4.2 times larger than that pre-PdNP/Zr-IPA surpasses most reported MOF-based reactions. Quenching electron paramagnetic resonance tests verified exposed (111) faces PdNP structure can react oxidants generate •O2- radicals, play dominant role benzaldehyde. Our work strategy confining MOFs enhance targeted

The catalytic hydrogen transfer (CHT) cascade reaction coupling alcohols with nitro compounds to synthesize imines is highly significant due its remarkable efficiency and atom economy. However, the complicated multistep process makes single-site catalysts exhibit unsatisfactory performance for CHT reaction. Herein, inspired by findings of DFT calculations that Co nanocluster (CoNC) single (CoSA) can act as optimal active sites alcohol oxidation reduction, respectively, one dual-active site catalyst (CoSA-CoNC/CN), containing CoSA CoNC sites, was synthesized a two-step vacuum pyrolysis strategy. Benefiting from relay-like tandem catalysis CoSA, CoSA-CoNC/CN achieved an impressive 93% nitrobenzene conversion 99% imine selectivity at 160 °C in 4 h, record turnover frequency 20.9 h–1. This work provides insights into functions single-atom sheds light on rational preparation catalysts.
